[Boost-users] [Graph] Disjoint Sets and Incremental Components with VertexList=listS

Hi all, I am quite new to boost and would appreciate a hint on the following matter. My doubt is related to what exactly does the API expects in terms of a ReadWriteProperty and currently I am not amble to figure it out how to instantiate a disjoint_set for a graph of type adjacency_list . The example (to a vecS graph) shows: std::vector rank(num_vertices(G)); std::vector<Vertex> parent(num_vertices(G)); typedef size_type* Rank; typedef Vertex* Parent; disjoint_sets ds(&rank[0], &parent[0]); I just spent some time trying different combinations of map and map but it does not work. Also tried boost::property_map::type for parent, but it didn't work either. Can anyone shed some light? thanks! Pedro
