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]=...
Dijkstra's algorithm 用于求解节点间权重为正的图网络中任意两个节点间的最短路径。即从图网络的所有还未进行边松弛(Edge Relaxtion)的节点中选取最靠近原始节点的节点。 边松弛的概念如下: if ( distance[相邻节点序号]>(相邻节点的边长+distance[起始节点序号]) ) { distance[相邻节点序号]=相邻节点的边长 +...
The .sssp.bellmanFord algorithm computes the shortest path distances from a single source vertex to all other vertices in the graph using the Bellman-Ford algorithm. Neptune Analytics implements the algorithm such that: Positive edge weights must be provided using the edgeWeightProperty field Negative...
Single-source shortest path (SSSP) is a well-known graph computation that has been studied for more than half a century. It is one of the most common graph analytical analyses in many research areas such as networks, communication, transportation, electronics, and so on. In this chapter, we...

Our experiments have established abstract results with the intention that the proposed algorithm can consistently dominate other existing algorithms for Single Source Shortest Path Problems. A comparison study is also shown among Dijkstra's algorithm, Bellman-Ford algorithm, and our algorithm....
We present a simple parallel algorithm for the single-source shortest path problem in planar digraphs with nonnegative real edge weights. The algorithm runs on the EREW PRAM model of parallel computation in O((n 2ε + n 1−ε) log n) time, performing O
