Web7 de jun. de 2004 · This paper addresses sensitivity analysis questions concerning the shortest path problem and the maximum capacity path problem in an undirected network. For both problems, we determine the maximum and minimum weights that each edge can have so that a given path remains optimal. For both problems, we show how to … Webpath whose bottleneck edge weight is equal to the maximum of the bottleneck edge weights of all paths from u to v. 3 The dominance approach We begin by revisiting an approach used by Chan [3] and Vassilevska and Williams [28] to find im-proved algorithms for all pairs shortest paths and maximum node-weighted triangles, respectively. In
WebA problem related both to APSP and APBP is the all pairs bottleneck shortest paths problem (APBSP), first considered by [21]. Consider a scenario in which we want to get from location u to location v in as few hops as possible, and subject to this, we wish to maximize the flow that we can route from u to v. WebThis paper presents a new heuristic algorithm tailored to solve large instances of an NP-hard variant of the shortest path problem, denoted the cost-balanced path problem, recently proposed in the literature. The problem consists in finding the origin–destination path in a direct graph, having both negative and positive weights associated with the arcs, such …
WebChoose the augmenting path with largest bottleneck value. It’s a fairly easy to show that the maximum-bottleneck (s,t)-path in a directed graph can be computed in O(ElogV)time using a variant of Jarník’s minimum-spanning-tree algorithm, or of Dijkstra’s shortest path algorithm. Simply grow a directed spanning tree T, rooted at s. Webcontrast, the s-t bottleneck path has algorithm with running time O(mβ(m,n)) [Chechik et al. 2016],whereβ(m,n) = min{k≥1 : log(k) n≤m n}. 2012ACMSubjectClassification Theoryofcomputation→Designandanalysisofalgorithms Keywordsandphrases GraphAlgorithm,BottleneckPath,CombinatorialOptimization DigitalObjectIdentifier …
