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...
的边(u, v)构成的边集。 令 为将每个 中的点连接到一个 中的点的边构成的集合。 思路:从i = 1到k,每次求出 中每个点对的误差为2(i-1)的最短路径长度,算完到i = k后,就把 中每个点对的误差为2(k-1)的最短路径长度给算出来了,这就是我们要求的。 i = 1的情况,直接在原图上(即 )对每个...

In this paper, we study the following all-pair shortest path query problem: Given the interval model of an unweighted interval graph of n vertices, build a data structure such that each query on the shortest path (or its length) between any pair of vertices of the graph can be processed...

摘要: A new algorithm for finding all the shortest paths has been put forward in this paper.All the shortest paths from one node to all the other nodes can be derived quickly by using the algorithm.The algorithm is verified by a C program....
