Minimum augmentation of local edge-connectivity between vertices and vertex subsets in undirected graphs
Given an undirected multigraph G = (V,E), a family W of sets W ⊆ V of vertices (areas), and a requirement function r : W → Z+ (where Z+ is the set of nonnegative integers), we consider the problem of augmenting G by the smallest number of new edges so that the resulting graph has at least r(W ) edge-disjoint paths between v and W for every pair of a vertex v ∈ V and an area W ∈ W. So far this p...
متن کاملIndependence Free Graphs and Vertex Connectivity Augmentation
Given an undirected graph G and a positive integer k, the k-vertex-connectivity augmentation problem is to find a smallest set F of new edges for which G + F is k-vertex-connected. Polynomial algorithms for this problem have been found only for k≤ 4 and a major open question in graph connectivity is whether this problem is solvable in polynomial time in general. In this paper we develop an algo...
متن کاملOn shredders and vertex connectivity augmentation
We consider the following problem: given a k-(node) connected graph G find a smallest set F of new edges so that the graph G + F is (k + 1)-connected. The complexity status of this problem is an open question. The problem admits a 2approximation algorithm. Another algorithm due to Jordán computes an augmenting edge set with at most d(k− 1)/2e edges over the optimum. C ⊂ V (G) is a k-separator (...
متن کاملUndirected Vertex-Connectivity Structure and Smallest Four-Vertex-Connectivity Augmentation
In this paper we study properties for the structure of an undirected graph that is not vertex connected We also study the evolution of this structure when an edge is added to optimally increase the vertex connectivity of the underlying graph Several properties reported here can be extended to the case of a graph that is not k vertex connected for an arbitrary k Using properties obtained here we...
متن کاملMinimum Weight Connectivity Augmentation for Planar Straight-Line Graphs
Connectivity augmentation is a classical problem in combinatorial optimization (see [4, 5]). Given a graph G = (V,E) and a parameter τ ∈ N, add a set of new edges E+ such that the augmented graph G′ = (V,E ∪ E+) is τ -connected (resp., τ -edge-connected). Over planar straightline graphs (PSLGs), it is NP-complete to find the minimum number of edges for τ -connectivity or τ -edge-connectivity au...
