Hi, I have two graphs and I want to know if they are isomorphic. I adjunct the graphs in .png. I read the documentation but i can't figure out how i must define the vertex invariant correctly. what I want is to consider that two graph are not isomorphic taking count of the vertices ids (the unsigned int value that they have). In the example i give I want the function isomorphism to return false. actually it return true. Thank you ! //////////////////////////////////////////////////////////////////////////////////////////// Graph graph1; Graph::vertex_descriptor aA = add_vertex(graph1); Graph::vertex_descriptor bA = add_vertex(graph1); Graph::vertex_descriptor cA = add_vertex(graph1); Graph::edge_descriptor edA1 = (add_edge(aA, bA, graph1)).first; Graph::edge_descriptor edA2 = (add_edge(bA, cA, graph1)).first; graph1[edA1].weight = 1; graph1[edA2].weight = 2; //////////////////////////////////////////////////////////////////////////////////////////// Graph graph2; Graph::vertex_descriptor aB = add_vertex(graph2); Graph::vertex_descriptor bB = add_vertex(graph2); Graph::vertex_descriptor cB = add_vertex(graph2); Graph::edge_descriptor edB1 = (add_edge(bB, aB, graph2)).first; Graph::edge_descriptor edB2 = (add_edge(aB, cB, graph2)).first; graph2[edB1].weight = 1; graph2[edB2].weight = 2; /////////////////////////////////////////////////////////////////////////////////////////// bool isIso = boost::isomorphism(graph1, graph2);
