longest path between two nodes for directed acyclic graph? - Google Groups Maximum flow doesn't work like that. It should distinguish the problem of "Longest Path" and the "Maximum Sum Path". Longest simple path with u as the end node ( V 1 u) will be m a x ( w ( u, u j) + V 1 u j) 1 j i which will be calculated in the O ( i) time. The problem is that a graph can admit multiple topological sorts.
