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...
In this paper, we consider one graph problem, the all pair shortest path problem and its implementation in OpenMP 3.0. We show that for large number of vertices, the algorithm running on OpenMP 3.0 surpasses the one on OpenMP 2.5 by 1.6 times. 展开 关键词: OpenMP 3.0 All Pair Shortest ...

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...

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....
