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,传统的单机算法难以有效解决全对最...
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...

Our algorithm is new in the following respect. It computes the distance μ( v, w) between each pair v, w of vertices even in the presence of negative cycles, where μ( v, w) is defined as the infimum of the costs of all directed paths from v to w....
Although an O(n^2)-algorithm for the incremental all-pairs shortest paths problem is known, previous experimental analysis has shown that algorithms with worse complexities perform significantly better and are therefore preferred in practice. In this paper, we propose a new incremental algorithm with...
