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 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...
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...

In the final step, we run Dijkstra’s algorithm for each vertex in the graph with the modified edges. After this step, we’ll have the shortest paths for each vertex pair . The shortest path weights are calculated using the modified edge weights. ...
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...
