WebFeb 13, 2024 · The Complexity of Bellman-Ford Algorithm. The Bellman-Ford algorithm emulates the shortest paths from a single source vertex to all other vertices in a weighted digraph. It is slower than Dijkstra's algorithm for the same problem but more versatile because it can handle graphs with some edge weights that are negative numbers. Web最短路径的4个常用算法是Floyd、Bellman-Ford、SPFA、Dijkstra。不同应用场景下，应有选择地使用它们： 图的规模小，用Floyd。若边的权值有负数，需要判断负圈。 图的规 …
