Is bellman ford dynamic programming

WebThe Bellman–Ford algorithm is an algorithm that computes shortest paths from a single source vertex to all of the other vertices in a weighted digraph. It is slower than Dijkstra's algorithm for the same problem, but more versatile, as it is capable of handling graphs in which some of the edge weights are negative numbers. Web因为如果存在负循环,最短路径就不存在,而且Bellman Ford可以检测到负循环,所以您可以说它从未失败过。(类似地,因为你可以检测两个顶点之间没有路径的情况) 没有路径的情况下?Dijkstra在有负边权重的情况下并不总是失败,它只是不总是成功。
