Fully Dynamic All Pairs All Shortest Paths

We consider the all pairs all shortest paths (APASP) problem, which maintains all of the multiple shortest paths for every vertex pair in a directed graph G = (V,E) with a positive real weight on each edge. We present a fully dynamic algorithm for this problem in which an update supports either weight increases or weight decreases on a subset of edges incident to a vertex. Our algorithm runs in...

All Pairs Shortest Paths Algorithms

Given a communication network or a road network one of the most natural algorithmic question is how to determine the shortest path from one point to another. In this paper we deal with one of the most fundamental problems of Graph Theory, the All Pairs Shortest Path (APSP) problem. We study three algorithms namely The FloydWarshall algorithm, APSP via Matrix Multiplication and the Johnson’s alg...

Average Update Times for Fully-Dynamic All-Pairs Shortest Paths

We study the fully-dynamic all pairs shortest path problem for graphs with arbitrary non-negative edge weights. It is known for digraphs that an update of the distance matrix costs Õ(n) worst-case time [Thorup, STOC ’05] and Õ(n) amortized time [Demetrescu and Italiano, J.ACM ’04] where n is the number of vertices. We present the first average-case analysis of the undirected problem. For a rand...

Fully Dynamic All Pairs Shortest Paths with Real Edge Weights

We present the first fully dynamic algorithm for maintaining all pairs shortest paths in directed graphs with real-valued edge weights. Given a dynamic directed graph G such that each edge can assume at most S different real values, we show how to support updates in O(n2.5 √ S log n ) amortized time and queries in optimal worst-case time. No previous fully dynamic algorithm was known for this p...

All - Pairs Shortest Paths ÆÆÆ

In the previous chapter, we saw algorithms to find the shortest path from a source vertex s to a target vertex t in a directed graph. As it turns out, the best algorithms for this problem actually find the shortest path from s to every possible target (or from every possible source to t) by constructing a shortest path tree. The shortest path tree specifies two pieces of information for each no...
