Hello All, I am getting little confused in defining the predicate for filtered graph since my properties are bundled. I need to compare two bundled property inside the predicate, I am not getting any idea of how to access this property there. Bundled property is declared as: struct Edgep { int edge_index; int edge_w; std::string edge_name; int capacity; int residual_capcity; int bandwidth_used; }; typedef subgraph< adjacency_list<vecS, vecS, undirectedS, Vertexp, property< edge_index_t, unsigned int, Edgep > > > Graph; I am creating the edge bundled property map as typedef bundle_property_map<Graph, Graph::edge_descriptor, Edgep, int> EM; I need to filter those edges whose bandwidth_used < residual_capacity. According to my understanding, I need to create a map to bandwidth_used and residual_capacity and pass this to predicate function. But can I define a predicate to take 2 different input maps or what is the better way to do this? I need some help at this part. Your suggestions would be of great help for me to proceed. -- Regards, Giridhar
