Webb6 apr. 2024 · Time Complexity: The main steps in the algorithm are Bellman-Ford Algorithm called once and Dijkstra called V times. Time complexity of Bellman Ford is O (VE) and time complexity of Dijkstra is O (VLogV). So overall time complexity is O (V 2 log V + VE).

Webb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。 free paint tool sai full version
