Hi All, I want to print a Boost Graph having custom(string) vertex labels instead of the default vertex numbering label 0,1,2... I have initialized the graph as : typedef adjacency_list > Graph; Graph g; set<string> names; map vertex ; for(auto it = names.begin() ; it != names.end(); ++it ) vertex[*it] = add_vertex(*it,g) ; Now how should I print this graph such that I get edges of the form abc -> xyz; instead of 1->2; Thanks and Regards, Shambwaditya
