Re: [Boost-users] prim_minimum_spanning_tree

Well Prims is not supposed to have problems with negative cycles. However Dijkstra does. I believe the problem lies in prim_minimum_spanning_tree use of Dijkstra.

Have done thanks. Was just wondering if it had been fixed in newer versions.

I think it fundamentally cannot be fixed, as the algorithm doesn't provide a way to detect the problematic conditions. ~ Scott
