OK, thanks. Now how do I declare a graph that does not allow parallel edges? ---------- Forwarded message ---------- From: moritz Hilger <moritz.hilger@gmail.com> Date: Sep 7, 2006 2:18 AM Subject: Re: [Boost-users] Why am I not hearing that my edge has already been added? To: boost-users@lists.boost.org The problem is that add_edge() never clears boolvar - it is always true,
even when I coerce redundant edges, as in the following code:
the problem is that your graph allows parallel edges, therefor the adding always succeeds. you would have to check for existing edges via out_edges(va). cheers, moritz _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
