all pair shortest path 分布式all pair shortest path分布式 全对最短路径问题(allpairshortestpath)是一个经典的图论问题,其目标是找到任意两个节点之间的最短路径。在分布式系统中,解决全对最短路径问题是十分重要的,因为它可以用于网络拓扑分析、路由协议等应用。 在分布式环境中,由于数据分散在不同的节点上,传统...

All-Pair Almost Shortest Path(APASP) 问题描述 给定一个n个点m条边的无向无权重的图,找出所有点对之间的近似最短距离。 思路 最简单的方法就是从每个点开始跑BFS了。BFS的时间复杂度是O(m)的,那么总的时间复杂度就是O(nm)的。但是如果是稠密图,那O(m)=O(n2),总的时间复杂度就是O(n3)了。所以思路...
As an immediate consequence of our results, we improve by a factor of n the space complexity of the previously best-known sequential all-pair shortest path algorithm for unweighted interval graphs. 1998 John Wiley & Sons, Inc. Networks 31: 249鈥 258, 1998...

Floyd-Warshall algorithm finds all shortest paths between every pair of vertexes in a graph. The algorithms was published by Robert Floyd in [1] (see “References” section for more details). In the same year, Peter Ingerman in [2] described a modern implementation of the algorithm in...
