Hi Jeremiah, Thanks for the quick responses. But since I am still a BGL newbie. I don't get what the predefined types are that I can use for my property map. What you seem to be suggesting sounds like a binary bitmap, which I have to check to set the filter or not for a vertex? So in the definition below for example, what would I replace "edge_weight_t" with? typedef property_map<Graph, edge_weight_t>::type EdgeWeightMap; (Example at http://www.boost.org/doc/libs/1_51_0/libs/graph/example/filtered_graph.cpp ) Could you maybe show me a quick example of just the property map ?
