Dijkstra 算法是求解有向图中单源最短距离(Single Source Shortest Path,简称为 SSSP)的经典算法。 最短距离:对一个有权重的有向图 G=(V,E),从一个源点 s 到汇点 v 有很多路径,其中边权和最小的路径,称从 s 到 v 的最短距离。 算法基本原理,如下所示: 初始化:源点 s 到 s 自身的距离(d[s]=...

Abstract:In undirected graphs with real non-negative weights, we give a new randomized algorithm for the single-source shortest path (SSSP) problem with running timeO(m⋅sqrt(logn⋅loglogn))in the comparison-addition model....
