Trac ticket 693 discusses the inclusion to trunk of the Bron Kerbosch cliques code from SOC 2007: https://svn.boost.org/trac/boost/ticket/693 Is there any documentation for this code in the boost::graph docs? I'm drawing a blank. First problem is that the example code is using typedef undirected_graph<Actor> Graph; which itself seems horribly documented. When I try to use a "real" undirected graph, I get compile errors stating that /usr/include/boost/graph/graph_concepts.hpp:455:13: error: no matching function for call to ‘renumber_vertex_indices(boost::adjacency_list<boost::vecS, boost::vecS, boost::undirectedS, boost::property<boost::vertex_name_t, unsigned int>, boost::property<boost::edge_weight_t, unsigned int> >&)’ Any tips? Thanks! Joel
