Hi, Recently,I tried to use Boost.Graph's VF2 implementation and after having played few days with this module, I was wondering if this implementation supports "adjacency_matrix" model as explained by the documentation (cf. http://www.boost.org/doc/libs/1_55_0/libs/graph/doc/vf2_sub_graph_iso.html). To demonstrate my point, you will find hereafter an C++ example extracted from the Boost.Graph's documentation. If the macro "ADJACENCY_LIST_STRUCT" is commented out, this code can't be compiled w/ VS2012 aka VC11 because the static assertion @line 837 of "boost/graph/vf2_sub_graph_iso.hpp" is triggered. My questions are: - Does this VF2 implementation supports "adjacency_matrix" model? - Is there any patch for supporting this model of graph? FYI: If I comment two static assertations in file "boost/graph/vf2_sub_graph_iso.hpp", at line 837 and line 843, the code compiles and runs correctly for "adjacency_matrix" model. #include #include #include using namespace boost; //#define ADJACENCY_LIST_STRUCT int main() { #ifdef ADJACENCY_LIST_STRUCT typedef adjacency_list graph_type; #else typedef adjacency_matrix<undirectedS> graph_type; #endif // Build graph1. const int num_vertices1 = 8; graph_type graph1(num_vertices1); add_edge(0, 6, graph1); add_edge(0, 7, graph1); add_edge(1, 5, graph1); add_edge(1, 7, graph1); add_edge(2, 4, graph1); add_edge(2, 5, graph1); add_edge(2, 6, graph1); add_edge(3, 4, graph1); // Build graph2. const int num_vertices2 = 9; graph_type graph2(num_vertices2); add_edge(0, 6, graph2); add_edge(0, 8, graph2); add_edge(1, 5, graph2); add_edge(1, 7, graph2); add_edge(2, 4, graph2); add_edge(2, 7, graph2); add_edge(2, 8, graph2); add_edge(3, 4, graph2); add_edge(3, 5, graph2); add_edge(3, 6, graph2); // Compute de subgraph isomorphing. vf2_print_callback cb(graph1, graph2); vf2_subgraph_iso(graph1, graph2, cb); } Best regards, Marc
