    + This constructor constructs a graph with numverts + vertices and the edges provided in the iterator range + [edge_begin, edge_end). Its semantics are identical + to the edge range constructor, except + that edge properties are also initialized. The type + EdgePropertyIterator must be a model of the InputIterator + concept whose value_type is convertible to + EdgeProperty. The iterator range [ep_iter, ep_ter + + m) will be used to initialize the properties on the edges + of the graph, where m is distance from + edge_begin to edge_end. This constructor uses extra + memory to save the edge information before adding it to the graph, + avoiding the requirement for the iterator to have multi-pass capability. + (This function is only provided by the new interface.) +

Subject: [PATCH 025/255] Removed x87 floating point precision workarounds as
 this was moved to boost/graph/relax.hpp in r54044.

This commit refs ticket #3134 as it will need to be merged to the release branch.

    + +

    + This algorithm finds all common subgraphs + between graph1 and graph2 and outputs them + to user_callback. The edges_equivalent + and vertices_equivalent predicates are used to + determine edges and vertex equivalence between the two graphs. + To use property maps for equivalence, look at + the make_property_map_equivalent + function. By + default, always_equivalent + tt used, which returns true for any pair of edges or vertices. +

    +

    + McGregor's algorithm does a depth-first search on the space of + possible common subgraphs. At each level, every unvisited pair + of vertices from graph1 and graph2 are checked + to see if they can extend the current subgraph. This is done in + three steps (assume vertex1 is + from graph1 and vertex2 is + from graph2): +

      +
    1. + Verify that the vertex1 and vertex2 are + equivalent using the vertices_equivalent predicate. +
      2. +
    2. + For every vertex pair + (existing_vertex1, existing_vertex2) in + the current subgraph, ensure that any edges + between vertex1 and existing_vertex1 + in graph1 and between vertex2 + and existing_vertex2 in graph2 match + (i.e. either both exist of both don't exist). If both edges + exist, they are checked for equivalence using + the edges_equivalent predicate. +
      3. +
    3. + Lastly (and optionally), make sure that the new subgraph + vertex has at least one edge connecting it to the existing + subgraph. When the only_connected_subgraphs + parameter is false, this step is skipped. +
      4. +
    +

    Where Defined

    + boost/graph/mcgregor_common_subgraphs.hpp + +

    Parameters

    + + IN: const GraphFirst& graph1 +
    + The first graph of the pair to be searched. The + type GraphFirst must be a model of + Vertex List Graph + and Incidence Graph. All + parameters with a "1" + (i.e. vindex_map1, correspondence_map_1_to_2) + use this graph's vertices as keys. +
    + + IN: const GraphSecond& graph2 +
    + The second graph of the pair to be searched. The + type Graphsecond must be a model of + Vertex List Graph + and Incidence Graph. All + parameters with a "2" + (i.e. vindex_map2, correspondence_map_2_to_1) + use this graph's vertices as keys. +
    + + IN: bool only_connected_subgraphs +
    + If true, subgraphs are expanded only when matching vertices + have at least one edge connecting them to the existing subgraph. +
    + + OUT: SubGraphCallback user_callback +
    + A function object that will be invoked when a subgraph has been discovered. The operator() must have the following form: +

    + Both the CorrespondenceMapFirstToSecond + and CorresondenceMapSecondToFirst types are models + of Readable + Property Map and map equivalent vertices across the two + graphs given to mcgregor_common_subgraphs. For + example, if vertex1 is + from graph1, vertex2 is from graph2, + and the vertices can be considered equivalent in the subgraph, + then get(correspondence_map_1_to_2, vertex1) will + be vertex2 and get(correspondence_map_2_to_1, + vertex2) will be vertex1. If any vertex, + say vertex1 in graph1, doesn't match a vertex + in the other graph (graph2 in this example), + then get(correspondence_map_1_to_2, vertex1) will + be graph_traits<GraphSecond>::null_vertex(). + Likewise for any un-matched vertices from graph2, + get(correspondence_map_2_to_1, vertex2) will + be graph_traits<GraphFirst>::null_vertex(). +

    The subgraph_size parameter is the number + of vertices in the subgraph, or the number of matched vertex + pairs contained in the correspondence maps. This can be used to + quickly filter out subgraphs whose sizes do not fall within the + desired range.

    Returning false from the + callback will abort the search immediately. Otherwise, the + entire search space will be explored [1]. +

    Named Parameters

    + Default: get(vertex_index, graph2) +
    + + IN: edges_equivalent(EdgeEquivalencePredicate edges_equivalent) +
    + This function is used to determine if edges + between graph1 and graph2 are equivalent. + The EdgeEquivalencePredicate type must be a model + of Binary + Predicate and have argument types + of graph_traits<GraphFirst>::edge_descriptor + and graph_traits<GraphSecond>::edge_descriptor. + A return value of true indicates that the edges are + equivalent.
    + Default: always_equivalent +

    + +

    Complexity

    +

    + The time complexity is O(?). +

    + +

    Examples

    +

    + Before calling any of the mcregor_common_subgraphs + algorithms, you must create a function object to act as a callback: +

    + 
    +template <typename GraphFirst,
+          typename GraphSecond>
+struct print_callback {
+
+  print_callback(const GraphFirst& graph1,
+                 const GraphSecond& graph2) :
+    m_graph1(graph1), m_graph2(graph2) { }
+
+template <typename CorrespondenceMapFirstToSecond,
+          typename CorrespondenceMapSecondToFirst>
+  bool operator()(CorrespondenceMapFirstToSecond correspondence_map_1_to_2,
+                  CorrespondenceMapSecondToFirst correspondence_map_2_to_1,
+                  typename graph_traits<GraphFirst>::vertices_size_type subgraph_size) {
+
+    // Print out correspondences between vertices
+    BGL_FORALL_VERTICES_T(vertex1, m_graph1, GraphFirst) {
+
+      // Skip unmapped vertices
+      if (get(correspondence_map_1_to_2, vertex1) != graph_traits<GraphSecond>::null_vertex()) {
+        std::cout << vertex1 << " <-> " << get(correspondence_map_1_to_2, vertex1) << std::endl;
+      }
+
+    }
+
+    std::cout << "---" << std::endl;
+
+    return (true);
+  }
+
+  private:
+    const GraphFirst& m_graph1;
+    const GraphSecond& m_graph2;
+
+};
+
+// Assuming the graph types GraphFirst and GraphSecond have already been defined
+GraphFirst graph1;
+GraphSecond graph2;
+
+print_callback<GraphFirst, GraphSecond> my_callback(graph1, graph2);
+
    + +

    Example 1

    +

    + If all the vertices and edges in your graph are identical, you + can start enumerating subgraphs immediately: +

    + 
    +// Print out all connected common subgraphs between graph1 and graph2.
+// All vertices and edges are assumed to be equivalent and both graph1 and graph2
+// have implicit vertex index properties.
+mcgregor_common_subgraphs(graph1, graph2, true, my_callback);
+
    + +

    Example 2

    +

    + If the vertices and edges of your graphs can be differentiated + with property maps, you can use + the make_property_map_equivalent function to create a + binary predicate for vertex or edge equivalence: +

    + + 
    +// Assume both graphs were defined with implicit vertex name,
+// edge name, and vertex index properties
+property_map<GraphFirst, vertex_name_t> vname_map1 = get(vertex_name, graph1);
+property_map<GraphSecond, vertex_name_t> vname_map1 = get(vertex_name, graph2);
+
+property_map<GraphFirst, edge_name_t> ename_map1 = get(edge_name, graph1);
+property_map<GraphSecond, edge_name_t> ename_map1 = get(edge_name, graph2);
+
+// Print out all connected common subgraphs between graph1 and graph2.
+mcgregor_common_subgraphs(graph1, graph2, true, my_callback,
+  edges_equivalent(make_property_map_equivalent(ename_map1, ename_map2)).
+  vertices_equivalent(make_property_map_equivalent(vname_map1, vname_map2)));
+
    + +

    Example 3

    +

    + There are some helper functions that can be used to obtain a + filtered graph from the correspondence maps given in your + callback: +

    + 
    +// Assuming we're inside the operator() of the callback with a member variable m_graph1 representing the first graph passed to mcgregor_common_subgraphs.
+// ...
+
+// Step 1: Transform a correspondence map into a membership map. Any vertex -> bool property map will work
+typedef shared_array_property_map MembershipMap;      
+MembershipMap membership_map1(num_vertices(m_graph1), get(vertex_index, m_graph1));
+
+// Fill the membership map for m_graph1. GraphSecond is the type of the second graph given to mcgregor_common_subgraphs.
+fill_membership_map<GraphSecond>(m_graph1, correspondence_map_1_to_2, membership_map1);
+
+// Step 2: Use the membership map from Step 1 to obtain a filtered graph
+typedef typename membership_filtered_graph_traits<GraphFirst, MembershipMap>::graph_type
+  MembershipFilteredGraph;
+
+MembershipFilteredGraph subgraph1 = make_membership_filtered_graph(m_graph1, membership_map1);
+
+// The filtered graph can be used like a regular BGL graph...
+BGL_FORALL_VERTICES_T(vertex1, subgraph1, MembershipFilteredGraph) {
+  std::cout << vertex1 << " is present in the subgraph of graph1" << std::endl;
+}
+
    + +

    Notes

    +

    + [1] + NOTE: For mcgregor_common_subgraphs_maximum + and mcgregor_common_subgraphs_maximum_unique the entire + search space is always explored, so the return value of the + callback has no effect. +

    -The maximum_cycle_ratio() function calculates the maximum cycle ratio of a weighted directed multigraph g=(V,E,W1,W2), where V is a vertex set, E is an edge set, W1 and W2 are edge weight functions, W2 is nonnegative.

    Let every edge e have two weights W1(e) and W2(e). Let c be a cycle of a graph g. The cycle ratio (cr(c)) is defined as:

    Cycle ratio definition


    -The maximum (minimum) cycle ratio (mcr) is the maximum (minimum) cycle ratio of all cycles of the graph. -Cycle calls critical if its ratio is equal to mcr.

    If the pcc parameter is not zero then one critical cycle will be written to the corresponding std::vector of edge descriptors. The edges in the vector stored in the way that *pcc[0], *ppc[1],...,*ppc[n] is a correct path.

    - -For a graph G=(V,E,W1,W2) let G'=(V,E,-W1,W2) be a graph with opposite W1 function, then the minimum cycle ratio of G is the opposite maximum cycle ratio of G'. -The minimum_cycle_ratio() function just calls the maximum_cycle_ratio() with the opposite W1 function, so if the type value of the W1 weight is integral then it must be signed. + +The maximum_cycle_ratio() function calculates the maximum cycle ratio of a +weighted directed multigraph G=(V,E,W1,W2), where V is a vertex set, +E is an edge set, W1 and W2 are edge weight functions, W2 is nonnegative. +As a multigraph, G can have multiple edges connecting a pair of vertices. +

    Let every edge e has two weights W1(e) and W2(e). +Let c be a cycle of the graphg. Then, the cycle ratio, cr(c), is defined as:

    +Cycle ratio definition +

    + +The maximum (minimum) cycle ratio (mcr) is the maximum (minimum) cycle ratio +of all cycles of the graph. A cycle is called critical if its ratio is equal +to the mcr. The calculated maximum cycle ratio will be the return value +of the function. The maximum_cycle_ratio()/minimum_cycle_ratio() returns +-FloatTraits::infinity()/FloatTraits::infinity() if graph has no cycles. +If the pcc parameter is not zero then one critical cycle will be written +to the corresponding std::vector of edge descriptors.

    The algorithm is due to Howard's iteration policy algorithm, descibed in [1]. Ali Dasdan, Sandy S. Irani and Rajesh K.Gupta in their paper Efficient Algorithms for Optimum Cycle Mean and Optimum Cost to Time Ratio Problemsstate that this is the most efficient algorithm to the time being (1999).

    IN: FloatTraits

    +
    +The FloatTrats encapsulates customizable limits-like information for +floating point types. This type must provide an associated type, +value_type for the floating point type. + +The default value is boost::mcr_float<>which has the following +definition:
    +
    + template <typename Float = double>

+    static Float infinity()
+    { return (std::numeric_limits<value_type>::max)(); }
+
+    static Float epsilon()
+    { return Float(-0.005); }
+  };
+
    +The value FloatTraits::epsilon() controls the "tolerance" of the +algorithm. By increasing the absolute value of epsilon you may slightly decrease +the execution time but there is a risk to skip a global optima. By decreasing +the absolute value you may fall to the infinite loop. The best option is to +leave this parameter unchanged. +

    + grid_graph +

    + +     + +

    Overview

    +

    + A grid_graph represents a multi-dimensional, + rectangular grid of vertices with user-defined dimension lengths + and wrapping. + +

    +

    + grid_graph models: +

    +

    +

    + Defined in + boost/graph/grid_graph.hpp + with all functions in the boost namespace. All examples are available in a single program file in libs/graph/example/grid_graph_example.cpp +

    + +

    Template Parameters

    + 
    +template <typename std::size_t Dimensions,
+          typename VertexIndex = std::size_t,
+          typename EdgeIndex = VertexIndex>
+  class grid_graph;
+
    +
      +
    • + Dimensions - Number of dimensions in the graph, must be greater than 2 +
      • +
    • + VertexIndex - Type used for vertex indices, defaults to std::size_t +
      • +
    • + EdgeIndex - Type used for edge indices, defaults to the same type as VertexIndex +
      • +
    + +

    Creating a Grid Graph

    +

    + The constructor to grid_graph has several overloads to aid in configuring each dimension: +

    + 
    +// Defines a grid_graph that does not wrap.
+grid_graph<...>(boost:array<VertexIndex, Dimensions> dimension_lengths);
+
+// Defines a grid_graph where all dimensions are either wrapped or unwrapped.
+grid_graph<...>(boost:array<VertexIndex, Dimensions> dimension_lengths,
+                bool wrap_all_dimensions);
+
+// Defines a grid_graph where the wrapping for each dimension is specified individually.
+grid_graph<...>(boost:array<VertexIndex, Dimensions> dimension_lengths,
+                boost:array<bool, Dimensions> wrap_dimension);
+
    + +

    Example

    + 
    +// Define dimension lengths, a 3x3 in this case
+boost::array<int, 2> lengths = { { 3, 3 } };
+
+// Create a 3x3 two-dimensional, unwrapped grid graph (Figure 1)
+grid_graph<2> graph(lengths);
+
+// Create a 3x3 two-dimensional, wrapped grid graph (Figure 2)
+grid_graph<2> graph(lengths, true);
+
+
    +

    + +
    + Figure 1: A 3x3 two-dimensional, unwrapped grid graph +

    +
    +

    + +
    + Figure 2: A 3x3 two-dimensional, wrapped grid graph +

    +
    + +

    Indexing

    +

    + The grid_graph supports addressing vertices and edges + by index. The following functions allow you to convert between + vertices, edges, and their associated indices: +

    + + 
    +typedef grid_graph<...> Graph;
+typedef graph_traits<Graph> Traits;
+
+// Get the vertex associated with vertex_index
+Traits::vertex_descriptor
+vertex(Traits::vertices_size_type vertex_index,
+       const Graph& graph);
+
+// Get the index associated with vertex
+Traits::vertices_size_type
+get(boost::vertex_index_t,
+    Traits::vertex_descriptor vertex,
+    const Graph& graph);
+
+// Get the edge associated with edge_index
+Traits::edge_descriptor
+edge_at(Traits::edges_size_type edge_index,
+        const Graph& graph);
+
+// Get the index associated with edge
+Traits::edges_size_type
+get(boost::edge_index_t,
+    Traits::edge_descriptor edge,
+    const Graph& graph);
+
+
    + +

    Example

    + 
    +typedef grid_graph<2> Graph;
+typedef graph_traits<Graph> Traits;
+
+// Create a 3x3, unwrapped grid_graph (Figure 3)
+boost::array<int, 2> lengths = { { 3, 3 } };
+Graph graph(lengths);
+
+// Do a round-trip test of the vertex index functions
+for (Traits::vertices_size_type v_index = 0;
+     v_index < num_vertices(graph); ++v_index) {
+
+  // The two indices should always be equal
+  std::cout << "Index of vertex " << v_index << " is " <<
+    get(boost::vertex_index, graph, vertex(v_index, graph)) << std::endl;
+
+}
+
+// Do a round-trip test of the edge index functions
+for (Traits::edges_size_type e_index = 0;
+     e_index < num_edges(graph); ++e_index) {
+
+  // The two indices should always be equal
+  std::cout << "Index of edge " << e_index << " is " <<
+    get(boost::edge_index, graph, edge_at(e_index, graph)) << std::endl;
+
+}
+
    + +

    Member Functions

    +

    + There are several grid_graph specific member functions available: +

    + 
    +typedef grid_graph<...> Graph;
+typedef graph_traits<Graph> Traits;
+
+// Returns the number of dimensions
+std::size_t dimensions();
+
+// Returns the length of a dimension
+Traits::vertices_size_type length(std::size_t dimension);
+
+// Returns true if the dimension wraps, false if not
+bool wrapped(std::size_t dimension);
+
+// Returns the "next" vertex in a dimension at a given distance. If the dimension
+// is unwrapped, next will stop at the last vertex in the dimension.
+Traits::vertex_descriptor next(Traits::vertex_descriptor vertex,
+                               std::size_t dimension,
+                               Traits::vertices_size_type distance = 1);
+
+// Returns the "previous" vertex in a dimension at a given distance. If the
+// dimension is unwrapped, previous will stop at the beginning vertex in the dimension.
+Traits::vertex_descriptor previous(Traits::vertex_descriptor vertex,
+                                   std::size_t dimension,
+                                   Traits::vertices_size_type distance = 1); 
+
    + +

    Example

    + 
    +typedef grid_graph<3> Graph;
+typedef graph_traits<Graph> Traits;
+
+// Define a 3x5x7 grid_graph where the second dimension doesn't wrap
+boost::array<std::size_t, 3> lengths = { { 3, 5, 7 } };
+boost::array<bool, 3> wrapped = { { true, false, true } };
+Graph graph(lengths, wrapped);
+
+// Print number of dimensions
+std::cout << graph.dimensions() << std::endl; // prints "3"
+
+// Print dimension lengths (same order as in the lengths array)
+std::cout << graph.length(0) << "x" << graph.length(1) <<
+  "x" << graph.length(2) << std::endl; // prints "3x5x7"
+
+// Print dimension wrapping (W = wrapped, U = unwrapped)
+std::cout << graph.wrapped(0) ? "W" : "U" << ", " <<
+  graph.wrapped(1) ? "W" : "U" << ", " <<
+  graph.wrapped(2) ? "W" : "U" << std::endl; // prints "W, U, W"
+
+// Define a simple function to print vertices
+void print_vertex(Traits::vertex_descriptor vertex_to_print) {
+  std::cout << "(" << vertex_to_print[0] << ", " << vertex_to_print[1] <<
+    ", " << vertex_to_print[2] << ")" << std::endl;
+}
+
+// Start with the first vertex in the graph
+Traits::vertex_descriptor first_vertex = vertex(0, graph);
+print_vertex(first_vertex); // prints "(0, 0, 0)"
+
+// Print the next vertex in dimension 0
+print_vertex(graph.next(first_vertex, 0)); // prints "(1, 0, 0)"
+
+// Print the next vertex in dimension 1
+print_vertex(graph.next(first_vertex, 1)); // prints "(0, 1, 0)"
+
+// Print the 5th next vertex in dimension 2
+print_vertex(graph.next(first_vertex, 2, 5)); // prints "(0, 0, 5)"
+
+// Print the previous vertex in dimension 0 (wraps)
+print_vertex(graph.previous(first_vertex, 0)); // prints "(2, 0, 0)"
+
+// Print the previous vertex in dimension 1 (doesn't wrap, so it's the same)
+print_vertex(graph.previous(first_vertex, 1)); // prints "(0, 0, 0)"
+
+// Print the 20th previous vertex in dimension 2 (wraps around twice)
+print_vertex(graph.previous(first_vertex, 2, 20)); // prints "(0, 0, 1)"

If the reader +has some previous acquaintance with graph algorithms, this chapter should be +enough to get started. If the reader has no previous background in graph +algorithms we suggest a more thorough introduction such as /Introduction to +Algorithms/ by Cormen, Leiserson, and Rivest. + +[h2 The Graph Abstraction] +A graph is a mathematical abstraction that is useful for solving many kinds of +problems. Fundamentally, a graph consists of a set of vertices, and a set of +edges, where an edge is something that connects two vertices in the graph. More +precisely, a graph is a pair (V,E), where V is a finite set and E is a binary +relation on V. V is called a vertex set whose elements are called vertices. E +is a collection of edges, where an edge is a pair (u,v) with u,v in V. In a +directed graph, edges are ordered pairs, connecting a source vertex to a target +vertex. In an undirected graph edges are unordered pairs and connect the two +vertices in both directions, hence in an undirected graph (u,v) and (v,u) are +two ways of writing the same edge. + +This definition of a graph is vague in certain respects; it does not say what a +vertex or edge represents. They could be cities with connecting roads, or +web-pages with hyperlinks. These details are left out of the definition of a +graph for an important reason; they are not a necessary part of the graph +abstraction. By leaving out the details we can construct a theory that is +reusable, that can help us solve lots of different kinds of problems. + +Back to the definition: a graph is a set of vertices and edges. For purposes of +demonstration, let us consider a graph where we have labeled the vertices with +letters, and we write an edge simply as a pair of letters. Now we can write down +an example of a directed graph as follows: + + G = (V, E) + V = {v, b, x, z, a, y } + E = { (b,y), (b,y), (y,v), (z,a), (x,x), (b,x), (x,v), (a,z) } + +Figure 1 gives a pictorial view of this graph. The edge (x,x) is called a +self-loop. Edges (b,y) and (b,y) are parallel edges, which are allowed in a +multigraph (but are normally not allowed in a directed or undirected graph). + +[$../../images/review_figure_1.png] + +Next we have a similar graph, though this time it is undirected. Figure 2 gives +the pictorial view. Self loops are not allowed in undirected graphs. This graph +is the undirected version(b,y)), meaning it has the same vertices and the same +edges with their directions removed. Also the self edge has been removed, and +edges such as (a,z) and (z,a) are collapsed into one edge. One can go the other +way, and make a directed version of an undirected graph be replacing each edge +by two edges, one pointing in each direction. + + G = (V, E) + V = {v, b, x, z, a, y } + E = { (b,y), (y,v), (z,a), (b,x), (x,v) } + +[$../../images/review_figure_2.png] + +Now for some more graph terminology. If some edge (u,v) is in graph , then +vertex v is adjacent to vertex u. In a directed graph, edge (u,v) is an out-edge +of vertex u and an in-edge of vertex v. In an undirected graph edge (u,v) is +incident on vertices u and v. + +In Figure 1, vertex y is adjacent to vertex b (but b is not adjacent to y). The +edge (b,y) is an out-edge of b and an in-edge of y. In Figure 2, y is adjacent +to b and vice-versa. The edge (y,b) is incident on vertices y and b. + +In a directed graph, the number of out-edges of a vertex is its out-degree and +the number of in-edges is its in-degree. For an undirected graph, the number of +edges incident to a vertex is its degree. In Figure 1, vertex b has an +out-degree of 3 and an in-degree of zero. In Figure 2, vertex b simply has a +degree of 2. + +Now a path is a sequence of edges in a graph such that the target vertex of each +edge is the source vertex of the next edge in the sequence. If there is a path +starting at vertex u and ending at vertex v we say that v is reachable from u. A +path is simple if none of the vertices in the sequence are repeated. The path +<(b,x), (x,v)> is simple, while the path <(a,z), (z,a)> is not. Also, the path +<(a,z), (z,a)> is called a cycle because the first and last vertex in the path +are the same. A graph with no cycles is acyclic. + +A planar graph is a graph that can be drawn on a plane without any of the edges +crossing over each other. Such a drawing is called a plane graph. A face of a +plane graph is a connected region of the plane surrounded by edges. An important +property of planar graphs is that the number of faces, edges, and vertices are +related through Euler's formula: |F| - |E| + |V| = 2. This means that a simple +planar graph has at most O(|V|) edges. + +[h2 Graph Data Structures] +The primary property of a graph to consider when deciding which data structure +to use is sparsity - the number of edges relative to the number of vertices in +the graph. A graph where E is close to V2 is a /dense graph/, whereas a graph +where E = alpha V and alpha is much smaller than V is a /sparse graph/. For +dense graphs, the adjacency-matrix representation is usually the best choice, +whereas for sparse graphs the adjacency-list representation is a better choice. +Also the edge-list representation is a space efficient choice for sparse graphs +that is appropriate in some situations. + +[h3 Adjacency Matrix Representation] +An adjacency-matrix representation of a graph is a 2-dimensional V x V array. +Each element in the array auv stores a Boolean value saying whether the edge +(u,v) is in the graph. Figure 3 depicts an adjacency matrix for the graph in +Figure 1 (minus the parallel edge (b,y)). The ammount of space required to store +an adjacency-matrix is O(V2). Any edge can be accessed, added, or removed in +O(1) time. To add or remove a vertex requires reallocating and copying the whole +graph, an O(V2) operation. The `adjacency_matrix<>` class implements the +Boost.Graph interface in terms of the adjacency-matrix data structure. + +[$../images/review_adjacency_matrix.gif] + +[h3 Adjacency List Representation] +An adjacency-list representation of a graph stores an out-edge sequence for each +vertex. For sparse graphs this saves space since only O(V + E) memory is +required. In addition, the out-edges for each vertex can be accessed more +efficiently. Edge insertion is O(1), though accessing any given edge is +O(alpha), where alpha is the sparsity factor of the matrix (which is equal to +the maximum number of out-edges for any vertex in the graph). Figure 4 depicts +an adjacency-list representation of the graph in Figure 1. The adjacency_list +class is an implementation of the adjacency-list representation. + +[$../images/review_adjacency_list.gif] + +[h3 Edge List Representation] +An edge-list representation of a graph is simply a sequence of edges, where each +edge is represented as a pair of vertex ID's. The memory required is only O(E). +Edge insertion is typically O(1), though accessing a particular edge is O(E) +(not efficient). Figure 5 shows an edge-list representation of the graph in +Figure 1. The edge_list adaptor class can be used to create implementations of +the edge-list representation. + +[$../images/review_edge_list.gif] + +[h3 Other Respresentations] +Add something here to discuss optimized storage options for the graph. +Specifically, we might mention the compressed-sparse-row graph representation +and its possible uses. + +[h2 Graph Algorithms] +Like all data structures, there are numerous algorithms that operate on them to +solve various problems. In fact, there are often several different approaches to +solving the same problem, each with different properties and complexities when +running on graphs with different properties (e.g., directed vs. undirected or +sparse vs. dense). The following sections briefly discuss a few such problems +and algorithms. + +[h3 Graph Search Algorithms] +Tree edges are edges in the search tree (or forest) constructed (implicitly or +explicitly) by running a graph search algorithm over a graph. An edge (u,v) is a +tree edge if v was first discovered while exploring (corresponding to the +visitor explore() method) edge (u,v). Back edges connect vertices to their +ancestors in a search tree. So for edge (u,v) the vertex v must be the ancestor +of vertex u. Self loops are considered to be back edges. Forward edges are +non-tree edges (u,v) that connect a vertex u to a descendant v in a search tree. +Cross edges are edges that do not fall into the above three categories. + +[h4 Breadth-First Search] +Breadth-first search (BFS) is a traversal through a graph that touches all of +the vertices reachable from a particular source vertex. In addition, the order +of the traversal is such that the algorithm will explore all of the neighbors of +a vertex before proceeding on to the neighbors of its neighbors. One way to +think of breadth-first search is that it expands like a wave emanating from a +stone dropped into a pool of water. Vertices in the same "wave" are the same +distance from the source vertex. A vertex is discovered the first time it is +encountered by the algorithm. A vertex is finished after all of its neighbors +are explored. Here's an example to help make this clear. A graph is shown in +Figure 6 and the BFS discovery and finish order for the vertices is shown below. + +[$../images/review_bfs.gif] + + order of discovery: s r w v t x u y + order of finish: s r w v t x u y + +We start at vertex , and first visit r and w (the two neighbors of ). Once both +neighbors of are visited, we visit the neighbor of r (vertex v), then the +neighbors of w (the discovery order between r and w does not matter) which are t +and x. Finally we visit the neighbors of t and x, which are u and y. + +For the algorithm to keep track of where it is in the graph, and which vertex to +visit next, BFS needs to color the vertices (see the section on Property Maps +for more details about attaching properties to graphs). The place to put the +color can either be inside the graph, or it can be passed into the algorithm as +an argument. + +[h4 Depth-First Search] +A depth-first search (DFS) visits all the vertices in a graph. When choosing +which edge to explore next, this algorithm always chooses to go "deeper" into +the graph. That is, it will pick the next adjacent unvisited vertex until +reaching a vertex that has no unvisited adjacent vertices. The algorithm will +then backtrack to the previous vertex and continue along any as-yet unexplored +edges from that vertex. After DFS has visited all the reachable vertices from a +particular source vertex, it chooses one of the remaining undiscovered vertices +and continues the search. This process creates a set of depth-first trees which +together form the depth-first forest. A depth-first search categorizes the edges +in the graph into three categories: tree-edges, back-edges, and forward or +cross-edges (it does not specify which). There are typically many valid +depth-first forests for a given graph, and therefore many different (and equally +valid) ways to categorize the edges. + +One interesting property of depth-first search is that the discover and finish +times for each vertex form a parenthesis structure. If we use an +open-parenthesis when a vertex is discovered, and a close-parenthesis when a +vertex is finished, then the result is a properly nested set of parenthesis. +Figure 7 shows DFS applied to an undirected graph, with the edges labeled in the +order they were explored. Below we list the vertices of the graph ordered by +discover and finish time, as well as show the parenthesis structure. DFS is used +as the kernel for several other graph algorithms, including topological sort and +two of the connected component algorithms. It can also be used to detect cycles +(see the Cylic Dependencies section of the File Dependency Example). + +[$../images/review_dfs.gif] + + order of discovery: a b e d c f g h i + order of finish: d f c e b a + parenthesis: (a (b (e (d d) (c (f f) c) e) b) a) (g (h (i i) h) g) + +[h4 Minimum Spanning Tree Problem] +The minimum-spanning-tree (MST) problem is defined as follows: Given a graph +/G=(V,E)/ find an acyclic subset /T/ of /E/ that connects all of the vertices in +the graph and whose total weight is minimized, where the total weight is given +by + +/w(T)/ = sum of /w(u,v)/ over all /(u,v)/ in T, where /w(u,v)/ is the weight on +the edge /(u,v)/. + +/T/ is called the minimum spanning tree of /G/. It is important to note that a +graph may have multiple MSTs. + +[h4 Shortest-Paths Algorithms] +One of the classic problems in graph theory is to find the shortest path between +two vertices in a graph. Formally, a path is a sequence of vertices + in a graph G = (V, E) such that each vertex is connected to the +next vertex in the sequence (the edges (vi,vi+1) for i=0,1,...,k-1 are in the +edge set E). In the shortest-path problem, each edge is given a real-valued +weight. We can therefore talk about the weight of a path + +/w(p)/ = sum from /i=1..k/ of /w(vi-1,vi)/ + +The shortest path weight from vertex /u/ to /v/ is then + +/delta(u,v)/ = min /{ w(p) : u --> v }/ if there is a path from u to v +/delta(u,v)/ = infinity otherwise. + +A shortest path is any path who's path weight is equal to the shortest path +weight. So there may be several shortest paths within the same graph. + +There are several variants of the shortest path problem. Above we defined the +single-pair problem, but there is also the single-source problem (all shortest +paths from one vertex to every other vertex in the graph), the equivalent +single-destination problem, and the all-pairs problem. It turns out that there +are no algorithms for solving the single-pair problem that are asymptotically +faster than algorithms that solve the single-source problem. + +A shortest-paths tree rooted at vertex in graph /G=(V,E)/ is a directed subgraph + where /V'/ is a subset of /V/ and /E'/ is a subset of /(E, V')/ is the set of +vertices reachable from , /G'/ forms a rooted tree with root , and for all /v/ +in /V'/ the unique simple path from to /v/ in /G'/ is a shortest path from to +/v/ in /G/. The result of a single-source algorithm is a shortest-paths tree. + +[h4 Network Flow Algorithms] +A flow network is a directed graph /G=(V,E)/ with a source vertex /s/ and a sink +vertex /t/. Each edge has a positive real valued capacity function c and there +is a flow function f defined over every vertex pair. The flow function must +satisfy three contraints: + +* /f(u,v) <= c(u,v)/ for all /(u,v)/ in /V/x /V/ (Capacity constraint) +* /f(u,v) = -f(v,u)/ for all /(u,v)/ in /V/ x /V/ (Skew symmetry) +* sum /v/ in /V/ /f(u,v)/ = 0 for all /u/ in /V/ - /{s,t}/ (Flow conservation) + +The flow of the network is the net flow entering the sink vertex t (which is +equal to the net flow leaving the source vertex s). + +/|f|/ = sum /u/ in /V/ /f(u,t)/ = sum /v/ in /V/ /f(s,v)/ + +The residual capacity of an edge is /r(u,v)/ = /c(u,v) - f(u,v)/. The edges with +/r(u,v) > 0/ are residual edges /Ef/ which induce the residual graph /Gf = (V, +Ef)/. An edge with /r(u,v) = 0/ is saturated. + +The maximum flow problem is to determine the maximum possible value for |/f/| +and the corresponding flow values for every vertex pair in the graph.

If the reader has some previous -acquaintance with graph algorithms, this chapter should be enough to get started. If the reader -has no previous background in graph algorithms we suggest a more thorough introduction such as -/Introduction to Algorithms/ by Cormen, Leiserson, and Rivest. - -[h2 The Graph Abstraction] -A graph is a mathematical abstraction that is useful for solving many kinds of problems. Fundamentally, -a graph consists of a set of vertices, and a set of edges, where an edge is something that connects two -vertices in the graph. More precisely, a graph is a pair (V,E), where V is a finite set and E is a binary -relation on V. V is called a vertex set whose elements are called vertices. E is a collection of edges, -where an edge is a pair (u,v) with u,v in V. In a directed graph, edges are ordered pairs, connecting a -source vertex to a target vertex. In an undirected graph edges are unordered pairs and connect the two -vertices in both directions, hence in an undirected graph (u,v) and (v,u) are two ways of writing the same -edge. - -This definition of a graph is vague in certain respects; it does not say what a vertex or edge represents. -They could be cities with connecting roads, or web-pages with hyperlinks. These details are left out of -the definition of a graph for an important reason; they are not a necessary part of the graph abstraction. -By leaving out the details we can construct a theory that is reusable, that can help us solve lots of -different kinds of problems. - -Back to the definition: a graph is a set of vertices and edges. For purposes of demonstration, let us -consider a graph where we have labeled the vertices with letters, and we write an edge simply as a pair -of letters. Now we can write down an example of a directed graph as follows: - - G = (V, E) - V = {v, b, x, z, a, y } - E = { (b,y), (b,y), (y,v), (z,a), (x,x), (b,x), (x,v), (a,z) } - -Figure 1 gives a pictorial view of this graph. The edge (x,x) is called a self-loop. Edges (b,y) and (b,y) -are parallel edges, which are allowed in a multigraph (but are normally not allowed in a directed or -undirected graph). - -[$../images/review_figure_1.png] - -Next we have a similar graph, though this time it is undirected. Figure 2 gives the pictorial view. -Self loops are not allowed in undirected graphs. This graph is the undirected version(b,y)), meaning it -has the same vertices and the same edges with their directions removed. Also the self edge has been -removed, and edges such as (a,z) and (z,a) are collapsed into one edge. One can go the other way, -and make a directed version of an undirected graph be replacing each edge by two edges, one pointing -in each direction. - - G = (V, E) - V = {v, b, x, z, a, y } - E = { (b,y), (y,v), (z,a), (b,x), (x,v) } - -[$../images/review_figure_2.png] - -Now for some more graph terminology. If some edge (u,v) is in graph , then vertex v is adjacent to vertex u. -In a directed graph, edge (u,v) is an out-edge of vertex u and an in-edge of vertex v. In an undirected graph -edge (u,v) is incident on vertices u and v. - -In Figure 1, vertex y is adjacent to vertex b (but b is not adjacent to y). The edge (b,y) is an out-edge -of b and an in-edge of y. In Figure 2, y is adjacent to b and vice-versa. The edge (y,b) is incident on -vertices y and b. - -In a directed graph, the number of out-edges of a vertex is its out-degree and the number of in-edges is -its in-degree. For an undirected graph, the number of edges incident to a vertex is its degree. In Figure 1, -vertex b has an out-degree of 3 and an in-degree of zero. In Figure 2, vertex b simply has a degree of 2. - -Now a path is a sequence of edges in a graph such that the target vertex of each edge is the source vertex -of the next edge in the sequence. If there is a path starting at vertex u and ending at vertex v we say -that v is reachable from u. A path is simple if none of the vertices in the sequence are repeated. The -path <(b,x), (x,v)> is simple, while the path <(a,z), (z,a)> is not. Also, the path <(a,z), (z,a)> is called -a cycle because the first and last vertex in the path are the same. A graph with no cycles is acyclic. - -A planar graph is a graph that can be drawn on a plane without any of the edges crossing over each other. -Such a drawing is called a plane graph. A face of a plane graph is a connected region of the plane -surrounded by edges. An important property of planar graphs is that the number of faces, edges, and -vertices are related through Euler's formula: |F| - |E| + |V| = 2. This means that a simple planar graph -has at most O(|V|) edges. - -[h2 Graph Data Structures] -The primary property of a graph to consider when deciding which data structure to use is sparsity - the -number of edges relative to the number of vertices in the graph. A graph where E is close to V2 is a -/dense graph/, whereas a graph where E = alpha V and alpha is much smaller than V is a /sparse graph/. For -dense graphs, the adjacency-matrix representation is usually the best choice, whereas for sparse graphs -the adjacency-list representation is a better choice. Also the edge-list representation is a space efficient -choice for sparse graphs that is appropriate in some situations. - -[h3 Adjacency Matrix Representation] -An adjacency-matrix representation of a graph is a 2-dimensional V x V array. Each element in the array -auv stores a Boolean value saying whether the edge (u,v) is in the graph. Figure 3 depicts an adjacency -matrix for the graph in Figure 1 (minus the parallel edge (b,y)). The ammount of space required to store -an adjacency-matrix is O(V2). Any edge can be accessed, added, or removed in O(1) time. To add or remove -a vertex requires reallocating and copying the whole graph, an O(V2) operation. The `adjacency_matrix<>` -class implements the Boost.Graph interface in terms of the adjacency-matrix data structure. - -[$../images/review_adjacency_matrix.gif] - -[h3 Adjacency List Representation] -An adjacency-list representation of a graph stores an out-edge sequence for each vertex. For sparse -graphs this saves space since only O(V + E) memory is required. In addition, the out-edges for each -vertex can be accessed more efficiently. Edge insertion is O(1), though accessing any given edge is -O(alpha), where alpha is the sparsity factor of the matrix (which is equal to the maximum number of -out-edges for any vertex in the graph). Figure 4 depicts an adjacency-list representation of the -graph in Figure 1. The adjacency_list class is an implementation of the adjacency-list representation. - -[$../images/review_adjacency_list.gif] - -[h3 Edge List Representation] -An edge-list representation of a graph is simply a sequence of edges, where each edge is represented -as a pair of vertex ID's. The memory required is only O(E). Edge insertion is typically O(1), though -accessing a particular edge is O(E) (not efficient). Figure 5 shows an edge-list representation of the -graph in Figure 1. The edge_list adaptor class can be used to create implementations of the edge-list -representation. - -[$../images/review_edge_list.gif] - -[h3 Other Respresentations] -Add something here to discuss optimized storage options for the graph. Specifically, we might -mention the compressed-sparse-row graph representation and its possible uses. - -[h2 Graph Algorithms] -Like all data structures, there are numerous algorithms that operate on them to solve various problems. -In fact, there are often several different approaches to solving the same problem, each with different -properties and complexities when running on graphs with different properties (e.g., directed vs. undirected -or sparse vs. dense). The following sections briefly discuss a few such problems and algorithms. - -[h3 Graph Search Algorithms] -Tree edges are edges in the search tree (or forest) constructed (implicitly or explicitly) by running a -graph search algorithm over a graph. An edge (u,v) is a tree edge if v was first discovered while -exploring (corresponding to the visitor explore() method) edge (u,v). Back edges connect vertices to -their ancestors in a search tree. So for edge (u,v) the vertex v must be the ancestor of vertex u. Self -loops are considered to be back edges. Forward edges are non-tree edges (u,v) that connect a vertex u -to a descendant v in a search tree. Cross edges are edges that do not fall into the above three categories. - -[h4 Breadth-First Search] -Breadth-first search (BFS) is a traversal through a graph that touches all of the vertices reachable -from a particular source vertex. In addition, the order of the traversal is such that the algorithm -will explore all of the neighbors of a vertex before proceeding on to the neighbors of its neighbors. -One way to think of breadth-first search is that it expands like a wave emanating from a stone dropped -into a pool of water. Vertices in the same ``wave'' are the same distance from the source vertex. A -vertex is discovered the first time it is encountered by the algorithm. A vertex is finished after -all of its neighbors are explored. Here's an example to help make this clear. A graph is shown in -Figure 6 and the BFS discovery and finish order for the vertices is shown below. - -[$../images/review_bfs.gif] - - order of discovery: s r w v t x u y - order of finish: s r w v t x u y - -We start at vertex , and first visit r and w (the two neighbors of ). Once both neighbors of are visited, -we visit the neighbor of r (vertex v), then the neighbors of w (the discovery order between r and w does -not matter) which are t and x. Finally we visit the neighbors of t and x, which are u and y. - -For the algorithm to keep track of where it is in the graph, and which vertex to visit next, BFS needs -to color the vertices (see the section on Property Maps for more details about attaching properties to -graphs). The place to put the color can either be inside the graph, or it can be passed into the algorithm -as an argument. - -[h4 Depth-First Search] -A depth-first search (DFS) visits all the vertices in a graph. When choosing which edge to explore next, -this algorithm always chooses to go ``deeper'' into the graph. That is, it will pick the next adjacent -unvisited vertex until reaching a vertex that has no unvisited adjacent vertices. The algorithm will then -backtrack to the previous vertex and continue along any as-yet unexplored edges from that vertex. After DFS -has visited all the reachable vertices from a particular source vertex, it chooses one of the remaining -undiscovered vertices and continues the search. This process creates a set of depth-first trees which together -form the depth-first forest. A depth-first search categorizes the edges in the graph into three categories: -tree-edges, back-edges, and forward or cross-edges (it does not specify which). There are typically many -valid depth-first forests for a given graph, and therefore many different (and equally valid) ways to -categorize the edges. - -One interesting property of depth-first search is that the discover and finish times for each vertex form -a parenthesis structure. If we use an open-parenthesis when a vertex is discovered, and a close-parenthesis -when a vertex is finished, then the result is a properly nested set of parenthesis. Figure 7 shows DFS applied -to an undirected graph, with the edges labeled in the order they were explored. Below we list the vertices of -the graph ordered by discover and finish time, as well as show the parenthesis structure. DFS is used as the -kernel for several other graph algorithms, including topological sort and two of the connected component -algorithms. It can also be used to detect cycles (see the Cylic Dependencies section of the File Dependency -Example). - -[$../images/review_dfs.gif] - - order of discovery: a b e d c f g h i - order of finish: d f c e b a - parenthesis: (a (b (e (d d) (c (f f) c) e) b) a) (g (h (i i) h) g) - -[h4 Minimum Spanning Tree Problem] -The minimum-spanning-tree (MST) problem is defined as follows: Given a graph /G=(V,E)/ find an acyclic -subset /T/ of /E/ that connects all of the vertices in the graph and whose total weight is minimized, where -the total weight is given by - -/w(T)/ = sum of /w(u,v)/ over all /(u,v)/ in T, where /w(u,v)/ is the weight on the edge /(u,v)/. - -/T/ is called the minimum spanning tree of /G/. It is important to note that a graph may have multiple MSTs. - -[h4 Shortest-Paths Algorithms] -One of the classic problems in graph theory is to find the shortest path between two vertices in a graph. -Formally, a path is a sequence of vertices in a graph G = (V, E) such that each vertex is -connected to the next vertex in the sequence (the edges (vi,vi+1) for i=0,1,...,k-1 are in the edge set E). -In the shortest-path problem, each edge is given a real-valued weight. We can therefore talk about the weight -of a path - -/w(p)/ = sum from /i=1..k/ of /w(vi-1,vi)/ - -The shortest path weight from vertex /u/ to /v/ is then - -/delta(u,v)/ = min /{ w(p) : u --> v }/ if there is a path from u to v -/delta(u,v)/ = infinity otherwise. - -A shortest path is any path who's path weight is equal to the shortest path weight. So there may be several -shortest paths within the same graph. - -There are several variants of the shortest path problem. Above we defined the single-pair problem, but there -is also the single-source problem (all shortest paths from one vertex to every other vertex in the graph), -the equivalent single-destination problem, and the all-pairs problem. It turns out that there are no -algorithms for solving the single-pair problem that are asymptotically faster than algorithms that solve -the single-source problem. - -A shortest-paths tree rooted at vertex in graph /G=(V,E)/ is a directed subgraph where /V'/ is a subset of -/V/ and /E'/ is a subset of /(E, V')/ is the set of vertices reachable from , /G'/ forms a rooted tree with -root , and for all /v/ in /V'/ the unique simple path from to /v/ in /G'/ is a shortest path from to /v/ in -/G/. The result of a single-source algorithm is a shortest-paths tree. - -[h4 Network Flow Algorithms] -A flow network is a directed graph /G=(V,E)/ with a source vertex /s/ and a sink vertex /t/. Each edge has -a positive real valued capacity function c and there is a flow function f defined over every vertex pair. -The flow function must satisfy three contraints: - -* /f(u,v) <= c(u,v)/ for all /(u,v)/ in /V/x /V/ (Capacity constraint) -* /f(u,v) = -f(v,u)/ for all /(u,v)/ in /V/ x /V/ (Skew symmetry) -* sum /v/ in /V/ /f(u,v)/ = 0 for all /u/ in /V/ - /{s,t}/ (Flow conservation) - -The flow of the network is the net flow entering the sink vertex t (which is equal to the net flow leaving -the source vertex s). - -/|f|/ = sum /u/ in /V/ /f(u,t)/ = sum /v/ in /V/ /f(s,v)/ - -The residual capacity of an edge is /r(u,v)/ = /c(u,v) - f(u,v)/. The edges with /r(u,v) > 0/ are residual -edges /Ef/ which induce the residual graph /Gf = (V, Ef)/. An edge with /r(u,v) = 0/ is saturated. - -The maximum flow problem is to determine the maximum possible value for |/f/| and the corresponding flow -values for every vertex pair in the graph. A flow network is shown in Figure 8. Vertex A is the source -vertex and H is the target vertex. - -[$../images/review_flow.gif] - -Edges are labeled with the flow and capacity values. There is a long history of algorithms for solving the -maximum flow problem, with the first algorithm due to Ford and Fulkerson. The best general purpose algorithm -to date is the push-relabel algorithm of Goldberg which is based on the notion of a preflow introduced by -Karzanov. - -[endsect] \ No newline at end of file From a04721f0ed7faa18b12667b045baeca134ed7dd1 Mon Sep 17 00:00:00 2001 From: Andrew Sutton Date: Thu, 3 Sep 2009 13:44:54 +0000 Subject: [PATCH 072/255] Added partial content for edge_list.

    + +

    +The find_odd_cycle function tests a given graph for bipartiteness +using a DFS-based coloring approach. +

    + +

    +An undirected graph is bipartite if one can partition its set of vertices +into two sets "left" and "right", such that each edge goes from either side +to the other. Obviously, a two-coloring of the graph is exactly the same as +a two-partition. is_bipartite() tests whether such a two-coloring +is possible and can return it in a given property map. +

    + +

    +Another equivalent characterization is the non-existance of odd-length cycles, +meaning that a graph is bipartite if and only if it does not contain a +cycle with an odd number of vertices as a subgraph. +find_odd_cycle() does nearly the same as +is_bipartite(), +but additionally constructs an odd-length cycle if the graph is found to be +not bipartite. +

    + +

    +The bipartition is recorded in the color map partition_map, +which will contain a two-coloring of the graph, i.e. an assignment of +black and white to the vertices such that no edge is monochromatic. +The odd-length cycle is written into the Output Iterator result if +one exists. The final final iterator is returned by the function. +

    + +

    Where Defined

    + +

    +boost/graph/bipartite.hpp +

    + +

    Parameters

    + +

    +IN: const Graph& graph +

    +

    +An undirected graph. The graph type must be a model of Vertex List Graph and Incidence Graph.
    +

    + +

    +IN: const IndexMap index_map +

    +

    +This maps each vertex to an integer in the range [0, +num_vertices(graph)). The type VertexIndexMap +must be a model of Readable Property +Map. The value type of the map must be an integer type. The +vertex descriptor type of the graph needs to be usable as the key +type of the map.
    +

    + + +

    +OUT: PartitionMap partition_map +

    +

    +The algorithm tests whether the graph is bipartite and assigns each +vertex either a white or a black color, according to the partition. +The PartitionMap type must be a model of +Readable Property +Map and +Writable Property +Map. The value type must model ColorValue. +

    + +

    +OUT: OutputIterator result +

    +

    +The find_odd_cycle function finds an odd-length cycle if the graph is +not bipartite. The sequence of vertices producing such a cycle is written +into this iterator. The OutputIterator type must be a model of + +OutputIterator. The graph's vertex descriptor type must be in the set +of value types of the iterator. The final value is returned by the +function. If the graph is bipartite (i.e. no odd-length cycle exists), nothing +is written, thus the given iterator matches the return value. +

    + + +

    Complexity

    + +

    +The time complexity for the algorithm is O(V + E). +

    Summary

    + +

    Various topologies are provided that +produce different, interesting results for graph layout algorithms. The square topology can be used for normal +display of graphs or distributing vertices for parallel computation on +a process array, for instance. Other topologies, such as the sphere topology (or N-dimensional ball topology) make sense for different +problems, whereas the heart topology is +just plain fun. One can also define a +topology to suit other particular needs.
    + +

    Topologies

    +A topology is a description of a space on which layout can be +performed. Some common two, three, and multidimensional topologies +are provided, or you may create your own so long as it meets the +requirements of the Topology concept. + +

    Topology Concept

     Let +Topology be a model of the Topology concept and let +space be an object of type Topology. p1 and +p2 are objects of associated type point_type (see +below). The following expressions must be valid: + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    ExpressionTypeDescription
    Topology::point_typetypeThe type of points in the space.
    space.random_point()point_typeReturns a random point (usually uniformly distributed) within + the space.
    space.distance(p1, p2)doubleGet a quantity representing the distance between p1 + and p2 using a path going completely inside the space. + This only needs to have the same < relation as actual + distances, and does not need to satisfy the other properties of a + norm in a Banach space.
    space.move_position_toward(p1, fraction, p2)point_typeReturns a point that is a fraction of the way from p1 + to p2, moving along a "line" in the space according to + the distance measure. fraction is a double + between 0 and 1, inclusive.
    + +

    Class template convex_topology

     + +

    Class template convex_topology implements the basic +distance and point movement functions for any convex topology in +Dims dimensions. It is not itself a topology, but is intended +as a base class that any convex topology can derive from. The derived +topology need only provide a suitable random_point function +that returns a random point within the space. + +

    +template<std::size_t Dims>
+class convex_topology 
+{
+  struct point 
+  {
+    point() { }
+    double& operator[](std::size_t i) {return values[i];}
+    const double& operator[](std::size_t i) const {return values[i];}
+
+  private:
+    double values[Dims];
+  };
+
+ public:
+  typedef point point_type;
+
+  double distance(point a, point b) const;
+  point move_position_toward(point a, double fraction, point b) const;
+};
+
    + +

    Class template hypercube_topology

     + +

    Class template hypercube_topology implements a +Dims-dimensional hypercube. It is a convex topology whose +points are drawn from a random number generator of type +RandomNumberGenerator. The hypercube_topology can +be constructed with a given random number generator; if omitted, a +new, default-constructed random number generator will be used. The +resulting layout will be contained within the hypercube, whose sides +measure 2*scaling long (points will fall in the range +[-scaling, scaling] in each dimension). + +

    +template<std::size_t Dims, typename RandomNumberGenerator = minstd_rand>
+class hypercube_topology : public convex_topology<Dims>
+{
+public:
+  explicit hypercube_topology(double scaling = 1.0);
+  hypercube_topology(RandomNumberGenerator& gen, double scaling = 1.0);
+  point_type random_point() const;
+};
+
    + +

    Class template square_topology

     + +

    Class template square_topology is a two-dimensional +hypercube topology. + +

    +template<typename RandomNumberGenerator = minstd_rand>
+class square_topology : public hypercube_topology<2, RandomNumberGenerator>
+{
+ public:
+  explicit square_topology(double scaling = 1.0);
+  square_topology(RandomNumberGenerator& gen, double scaling = 1.0);
+};
+
    + +

    Class template cube_topology

     + +

    Class template cube_topology is a two-dimensional +hypercube topology. + +

    +template<typename RandomNumberGenerator = minstd_rand>
+class cube_topology : public hypercube_topology<3, RandomNumberGenerator>
+{
+ public:
+  explicit cube_topology(double scaling = 1.0);
+  cube_topology(RandomNumberGenerator& gen, double scaling = 1.0);
+};
+
    + +

    Class template ball_topology

     + +

    Class template ball_topology implements a +Dims-dimensional ball. It is a convex topology whose points +are drawn from a random number generator of type +RandomNumberGenerator but reside inside the ball. The +ball_topology can be constructed with a given random number +generator; if omitted, a new, default-constructed random number +generator will be used. The resulting layout will be contained within +the ball with the given radius. + +

    +template<std::size_t Dims, typename RandomNumberGenerator = minstd_rand>
+class ball_topology : public convex_topology<Dims>
+{
+public:
+  explicit ball_topology(double radius = 1.0);
+  ball_topology(RandomNumberGenerator& gen, double radius = 1.0); 
+  point_type random_point() const;
+};
+
    + +

    Class template circle_topology

     + +

    Class template circle_topology is a two-dimensional +ball topology. + +

    +template<typename RandomNumberGenerator = minstd_rand>
+class circle_topology : public ball_topology<2, RandomNumberGenerator>
+{
+ public:
+  explicit circle_topology(double radius = 1.0);
+  circle_topology(RandomNumberGenerator& gen, double radius = 1.0);
+};
+
    + +

    Class template sphere_topology

     + +

    Class template sphere_topology is a two-dimensional +ball topology. + +

    +template<typename RandomNumberGenerator = minstd_rand>
+class sphere_topology : public ball_topology<3, RandomNumberGenerator>
+{
+ public:
+  explicit sphere_topology(double radius = 1.0);
+  sphere_topology(RandomNumberGenerator& gen, double radius = 1.0);
+};
+
    + +

    Class template heart_topology

     + +

    Class template heart_topology is topology in the shape of +a heart. It serves as an example of a non-convex, nontrivial topology +for layout. + +

    +template<typename RandomNumberGenerator = minstd_rand>
+class heart_topology 
+{
+ public:
+  typedef unspecified point_type;
+
+  heart_topology();
+  heart_topology(RandomNumberGenerator& gen);
+  point_type random_point() const;
+  double distance(point_type a, point_type b) const;
+  point_type move_position_toward(point_type a, double fraction, point_type b) const;
+};

    The boykov_kolmogorov_max_flow() function calculates the maximum +flow of a network. See Section Network +Flow Algorithms for a description of maximum flow. The calculated +maximum flow will be the return value of the function. The function +also calculates the flow values f(u,v) for all (u,v) in +E, which are returned in the form of the residual capacity +r(u,v) = c(u,v) - f(u,v). +

    +

    Requirements:
    The directed graph G=(V,E) that +represents the network must include a reverse edge for every edge in +E. That is, the input graph should be Gin = +(V,{E U ET}). The ReverseEdgeMap argument rev +must map each edge in the original graph to its reverse edge, that is +(u,v) -> (v,u) for all (u,v) in E. +

    + +

    Remarks: While the push-relabel method states that each edge in ET +has to have capacity of 0, the reverse edges for this algorithm ARE +allowed to carry capacities. If there are already reverse edges in +the input Graph G, +those can be used. This can halve the amount of edges and will +noticeably increase the performance.

    + +

    +Algorithm description:
    The Boykov-Kolmogorov max-flow (or often +BK max-flow) algorithm is a variety of the augmenting-path algorithm. Standard +augmenting path algorithms find shortest paths from source to sink vertex and +augment them by substracting the bottleneck capacity found on that path from the +residual capacities of each edge and adding it to the total flow. Additionally +the minimum capacity is added to the residual capacity of the reverse edges. If +no more paths in the residual-edge tree are found, the algorithm terminates. +Instead of finding a new shortest path from source to sink in the graph in each +iteration, Kolmogorov's version keeps the already found paths as follows:

    + +

    The algorithm builds up two search trees, a source-tree and a +sink-tree. Each vertex has a label (stored in ColorMap) to +which tree it belongs and a status-flag if this vertex is active or +passive. In the beginning of the algorithm only the source and the +sink are colored (source==black, sink==white) and have active status. +All other vertices are colored gray. The algorithm consists of three +phases:

    +

    grow-phase: In this phase active vertices are allowed to +acquire neighbor vertices that are connected through an edge that has +a capacity-value greater than zero. Acquiring means that those vertices +become active and belong now to the search tree of the current +active vertex. If there are no more valid connections to neighbor +vertices, the current vertex becomes passive and the grow phase +continues with the next active vertex. The grow phase terminates if +there are no more active vertices left or a vertex discovers a vertex +from the other search tree through an unsaturated edge. In this case +a path from source to sink is found.

    +

    augment-phase: This phase augments the path that was found +in the grow phase. First it finds the bottleneck capacity of the +found path, and then it updates the residual-capacity of the edges +from this path by substracting the bottleneck capacity from the +residual capacity. Furthermore the residual capacity of the reverse +edges are updated by adding the bottleneck capacity. This phase can +destroy the built up search trees, as it creates at least one +saturated edge. That means, that the search trees collapse to +forests, because a condition for the search trees is, that each +vertex in them has a valid (=non-saturated) connection to a terminal.

    +

    adoption-phase: Here the search trees are reconstructed. A +simple solution would be to mark all vertices coming after the first +orphan in the found path free vertices (gray). A more sophisticated +solution is to give those orphans new parents: The neighbor vertices +are checked if they have a valid connection to the same terminal like +this vertex had (a path with unsaturated edges). If there is one, +this vertex becomes the new parent of the current orphan and this +forest is re-included into the search tree. If no new valid parent is +found, this vertex becomes a free vertex (marked gray), and it's +children become orphans. The adoption phase terminates if there are +no more orphans.

    +


    Details:

    +
      +

    • Marking heuristics: A timestamp is stored for each vertex + which shows in which iteration of the algorithm the distance to the + corresponding terminal was calculated. +

      +
        +

      • This distance is used and gets calculated in the + adoption-phase. In order to find a valid new parent for an orphan, + the possible parent is checked for a connection to the terminal to + which tree it belongs. If there is such a connection, the path is + tagged with the current time-stamp, and the distance value. If + another orphan has to find a parent and it comes across a vertex + with a current timestamp, this information is used.

        +

      • The distance is also used in the grow-phase. If a vertex + comes across another vertex of the same tree while searching for + new vertices, the other's distance is compared to its distance. If + it is smaller, that other vertex becomes the new parent of the + current. This can decrease the length of the search paths, and so + amount of adoptions.

        +
      +

    • Ordering of orphans: As described above, the augment-phase + and the adoption phase can create orphans. The orphans the + augment-phase generates, are ordered according to their distance to + the terminals (smallest first). This combined with the + distance/timestamp heuristics results in the possibility for not + having to recheck terminal-connections too often. New orphans which + are generated in adoption phase are processed before orphans from + the main queue for the same reason.

      +
    +


    Implementation notes:

    +

    The algorithm is mainly implemented as described by Boykov and Kolmogorov in +[69]. An extended version +can be found in the PhD Thesis of Kolmogorov [68]. +The following changes are made to improve performance:

    +
      +
    • initialization: the algorithm first augments all paths from + source->sink and all paths from source->VERTEX->sink. This + improves especially graph-cuts used in image vision where nearly + each vertex has a source and sink connect. During this step, all + vertices that have an unsaturated connection from source are added + to the active vertex list and so the source is not.
      • +
    • active vertices: Kolmogorov uses two lists for active nodes + and states that new active vertices are added to the rear of the + second. Fetching an active vertex is done from the beginning of the + first list. If the first list is empty, it is exchanged by the + second. This implementation uses just one list.
      • +
    • grow-phase: In the grow phase the first vertex in the + active-list is taken and all outgoing edges are checked if they are + unsaturated. This decreases performance for graphs with high-edge + density. This implementation stores the last accessed edge and + continues with it, if the first vertex in the active-list is the + same one as during the last grow-phase.

    + +

    +The random_spanning_tree() function generates a random spanning tree +on a directed or undirected graph. The algorithm used is Wilson's algorithm (73, based on loop-erased random walks. There must +be a path from every non-root vertex of the graph to the root; +the algorithm typically enters an infinite loop when +given a graph that does not satisfy this property, but may also throw the +exception loop_erased_random_walk_stuck if the search reaches a vertex +with no outgoing edges. Both weighted and unweighted versions of +random_spanning_tree() are +implemented. In the unweighted version, all spanning trees are equally likely. +In the weighted version, the probability of a particular spanning tree being +selected is the product of its edge weights. +In the non-named-parameter +version of the algorithm, the unweighted version can be selected by passing an +object of type static_property_map<double> as the weight map. +In the named-parameter version, leaving off the weight_map parameter +has the same effect. +

    + +

    Where Defined

    + +

    +boost/graph/random_spanning_tree.hpp + +

    Parameters

    + +IN: const Graph& g +
    + An undirected graph. The graph type must + be a model of Incidence Graph + and Vertex List Graph.
    +
    + +IN: Gen& gen +
    + A random number generator. The generator type must + be a model of Uniform + Random Number Generator or a pointer or reference to such a type.
    +
    + + +

    Named Parameters

    + +IN: root_vertex(vertex_descriptor root) +
    + This parameter, whose type must be the vertex descriptor type of + Graph, gives the root of the tree to be generated. The default is + *vertices(g).first.
    +
    + +UTIL: color_map(ColorMap color) +
    + This is used by the algorithm to keep track of its progress through + the graph. The type ColorMap must be a model of Read/Write + Property Map and its key type must be the graph's vertex + descriptor type and the value type of the color map must model + ColorValue.
    + Default: a two_bit_color_map of size + num_vertices(g) and using the i_map for the index + map.
    +
    + +IN: vertex_index_map(VertexIndexMap i_map) +
    + This maps each vertex to an integer in the range [0, + num_vertices(g)). This parameter is only necessary when the + default color property map is used. The type VertexIndexMap + must be a model of Readable Property + Map. The value type of the map must be an integer type. The + vertex descriptor type of the graph needs to be usable as the key + type of the map.
    +
    + +OUT: predecessor_map(PredMap pred) +
    + This map, on output, will contain the predecessor of each vertex in the graph + in the spanning tree. The value + graph_traits<Graph>::null_vertex() will be used as the + predecessor of the root of the tree. The type PredMap must be a + model of + Read/Write Property + Map. The key and value types of the map must both be the graph's vertex type.
    +
    + +IN: weight_map(WeightMap weight) +
    + This map contains the weight of each edge in the graph. The probability of + any given spanning tree being produced as the result of the algorithm is + proportional to the product of its edge weights. If the weight map is + omitted, a default that gives an equal weight to each edge will be used; a + faster algorithm that relies on constant weights will also be invoked. + The type WeightMap must be a + model of + Readable Property + Map. The key type of the map must be the graph's edge type, and the value + type must be a real number type (such as double).

    UpdatableQueue

    + +

    An UpdatableQueue is a refinement of the Buffer concept that additionally requires that the Buffer be updatable. + +

    Implicit in the definition is an ordering of values. Though access to the order is not required, types that model UpdatableQueue must document how an object of the type orders values so that a program may change the position of a given value in the ordering. For example, an UpdatableQueue may choose to order values by using a property map, and a value v1 is considered less than a value v2 if get(pm, v1) < get(pm, v2). A program can update the properties of values, thus changing the order of values in the UpdatableQueue, and notify the UpdatableQueue of the specific values that have a different position in the ordering by calling the update member of the UpdatableQueue on each. + +

    A program that modifies the order must notify the UpdatableQueue of values that may have different positions in the ordering since they were inserted or last updated. + +

    T is the value type of Q.

    UpdatablePriorityQueue

    +

    An UpdatablePriorityQueue is a slight refinement of UpdatableQueue +that imposes the requirement that a program may not increase the position of a value that is held in the queue. That is, +if a value v had position n in the ordering, a program may update the position of v only to 0, 1, ..., n - 1, or n, where 0 is the top of the queue. + +

    The behavior when a program attempts to increase a value's position in the ordering is undefined. + +

    stoer_wagner_min_cut

    + + + +

    +

+weight_type
+stoer_wagner_min_cut(const UndirectedGraph& g, WeightMap weights,
+    const bgl_named_params<P, T, R>& params = all defaults);
+
    + +

    The stoer_wagner_min_cut function determines a min-cut and the min-cut weight of a connected, undirected graph. + +

    A cut of a graph G is a partition of the vertices into two, non-empty sets. The weight of such a partition is the number of edges between the two sets if G is unweighted, or the sum of the weights of all edges between the two sets if G is weighted. A min-cut is a cut having the least weight. + +

    Sometimes a graph has multiple min-cuts, but all have the same weight. The stoer_wagner_min_cut function determines exactly one of the min-cuts as well as its weight. + +

    Where Defined

    +

    boost/graph/stoer_wagner_min_cut.hpp + +

    Parameters

    + +

    IN: const UndirectedGraph& g +

    + A connected, undirected graph. The graph type must be a model of + Vertex List Graph + and Incidence Graph. +
    + +

    IN: WeightMap weights +

    + The weight or length of each edge in the graph. The WeightMap type must be a model + of Readable + Property Map and its value type must be Less Than + Comparable and summable. The key type of this map needs to be the graph's + edge descriptor type. +
    + +

    Named Parameters

    + +

    OUT: parity_map(ParityMap parities) +

    + The algorithm computes a min-cut, which divides the set of vertices into two, + non-empty sets. The stoer_wagner_min_cut function records which of + the two sets that each vertex belongs to by setting the parity to true + (representing one set) or false (for the other). ParityMap + must be a model of a Writable + Property Map and its value type should be a bool type. The + key type must be the graph's vertex descriptor type.
    + Default: boost::dummy_property_map +
    + +

    Expert Parameters

    + +

    IN: vertex_index_map(VertexIndexMap vertexIndices) +

    + This maps each vertex to an integer in the range [0, num_vertices(g)). This + is only necessary if the default is used for the assignment, index-in-heap, or distance maps. + VertexIndexMap must be a model of Readable Property + Map. The value type of the map must be an integer type. The + key type must be the graph's vertex descriptor type.
    + Default: get(boost::vertex_index, g) +
    + +

    UTIL: assignment_map(AssignmentMap assignments) +

    + AssignmentMap must be a model of Read/Write Property + Map. The key and value types must be the graph's vertex descriptor type.
    + Default: A boost::iterator_property_map using a std::vector + of num_vertices(g) vertex descriptors and vertexIndices for + the index map. +
    + +

    UTIL: max_priority_queue(MaxPriorityQueue& pq) +

    + MaxPriorityQueue must be a model of Keyed Updatable Queue + and a max-Updatable Priority Queue. + The value type must be the graph's vertex descriptor and the key type must be + the weight type. + Default: A boost::d_ary_heap_indirect using a default index-in-heap + and distance map. +
    + +

    UTIL: index_in_heap_map(IndexInHeapMap indicesInHeap) +

    + This parameter only has an effect when the default max-priority queue is used.
    + IndexInHeapMap must be a model of Read/Write Property + Map. The key type must be the graph's vertex descriptor type. The value type + must be a size type (typename std::vector<vertex_descriptor>::size_type).
    + Default: A boost::iterator_property_map using a std::vector + of num_vertices(g) size type objects and vertexIndices for + the index map. +
    + +

    UTIL: distance_map(DistanceMap wAs) +

    + This parameter only has an effect when the default max-priority queue is used.
    + DistanceMap must be a model of Read/Write Property + Map. The key type must be the graph's vertex descriptor type. The value type + must be the weight type (typename boost::property_traits<WeightMap>::value_type).
    + Default: A boost::iterator_property_map using a std::vector + of num_vertices(g) weight type objects and vertexIndices for + the index map. +
    + +

    Returns

    +

    The weight of the min-cut + +

    Throws

    + +

    bad_graph +

    + If num_vertices(g) is less than 2 +
    + +

    std::invalid_argument +

    + If a max-priority queue is given as an argument and it is not empty +
    + +

    Complexity

    + +

    The time complexity is O(V·E + V2 log V). + +

    Example

    + +

    The file examples/stoer_wagner.cpp contains an example of calculating a min-cut of a weighted, undirected graph and its min-cut weight. + +
