WebThe Bellman-Ford algorithm does not work on undirected graphs with negative weights, because $(u,v)$ and $(v,u)$ are not allowed on the same path, but the Bellman-Ford algorithm does not handle this constraint. In fact, if the weight of $(u,v)$ is negative, $(u,v)$ and $(v,u)$ form a negative cycle. granite graphicsWebBellman-Ford Algorithm is an algorithm for single source shortest path where edges can be negative (but if there is a cycle with negative weight, then this problem will be NP)..
