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]=0),其
步骤1:初始化起始节点(source node)到自身的距离为0,到其他所有节点的距离为无穷大。 将包含所有节点的数据对 <节点号,和起始节点的距离>组成字典。即<0,0>为起始节 点0和起始节点0到其自身的距离0。见下图。 步骤2:从字典移除数据对<0,0>并松弛连接起始点0和相邻节点的边。这样可得到距离起始点 0最近...

Single Source Shortest Path (SSSP) is one of the widely occurring graph problems where the paths are discovered from an origin vertex to all other vertices in the graph. In this paper, we discuss our experience parallelizing SSSP using OpenSHMEM. We start with the...Aderholdt, Ferrol...

In this paper, a faster single-source shortest path algorithm for nonnegative weight graph is proposed. The time complexity interval of the algorithm is (O(m+n),O(m+nlgn)) where m is the number of edges and n is the number of nodes. Based on the theoretical analyses, we demonstrate ...
