SPFA 算法(Shortest Path Faster Algorithm) 一、算法背景 求单源最短路的SPFA算法的全称是:Shortest Path Faster Algorithm。 SPFA算法是西南交通大学段凡丁于1994年发表的。 有人称spfa算法是最短路的万能算法。 二、适用范围: 给定的图存在负权边,这时类似Dijkstra等算法便没有了用武之地,而Bellman-Ford算法的...
Problem: You want to find the shortest path between two nodes on a weighted graph. Solution:Use Dijkstra’s algorithm to find the shortest path between two nodes.Dijkstra’s algorithm also uses a priority queue, which can be implemented using a min heap. ...
