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...

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 +...
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]=...
One of the most challenging problems in large scale dynamic graphs is the single-source shortest path (SSSP) problem. Traditional solutions (based on Dijkstra's algorithms) to the SSSP problem do not scale to large dynamic graphs with a high change frequency. In this paper, we propose an ...
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...

We show how to solve a single source shortest path problem on a planar network in time O(n 3/2 log n). The algorithm works for arbitrary edge weights (positive and negative) and is based on the planar separator theorem. More generally, the algorithm works in time O(n a+b log n +...
