Re: [Boost-users] [graph] Bug - add_edge (adjacency_list) does not report if edge already exists as stated in documentation

Hi Dmitry,

thanks for your reply. Yes this might fix the problem. But than the documentation of "add_edge" is missleading because it should hold for vecS too.

Unfortunately I have to stick to vecS due to some other reasons like automatic vertex indexing via properties etc. So I used the workaround with first checking for the presence of the edge via "edge(..).second". Remember, that first template argument of an boost::adjacency_list<> determines OutEdgeList container.

boost::adjacency_list
