The Shortest Path Faster Algorithm (SPFA) is an improvement of the Bellman-Ford algorithm. It computes the shortest paths from a single source vertex to all other vertices in a weighted directed graph. The SPFA has a worst-case runtime equal to that of the Bellman-Ford algorithm, but in practice it has been observed to be much faster.
Webspfa就是队列优化的bellman_ford算法 使用spfa判断图中是否存在负环的话,有两种方法 判断一个点是不是已经进入队列了n次,由bellman_ford算法可以知道,如果不存在负环最多经过n次迭代就可以得到1到任何一个点的最短距离,一个点最多被更新n-1次 判断到当前点的最短路径长度是不是大于等于n了! 如果是的话,就说明存在一条路径有n的长度,那么该 … WebContribute to fengchen321/ACwing_Basic_Algorithm_Course development by creating an account on GitHub.
