Linear-time approximation schemes for planar minimum three-edge connected and three-vertex connected spanning subgraphs

چکیده
We present the first polynomial-time approximation schemes, i.e., (1 + )-approximation algorithm for any constant > 0, for the minimum three-edge connected spanning subgraph problem and the minimum three-vertex connected spanning subgraph problem in undirected planar graphs. Both the approximation schemes run in linear time. This material is based upon work supported by the National Science Foundation under Grant No. CCF1252833. ar X iv :1 70 1. 08 31 5v 1 [ cs .D S] 2 8 Ja n 20 17

Approximation Schemes for Minimum 2-Connected Spanning Subgraphs in Weighted Planar Graphs
We present new approximation schemes for various classical problems of finding the minimum-weight spanning subgraph in edgeweighted undirected planar graphs that are resistant to edge or vertex removal. We first give a PTAS for the problem of finding minimum-weight 2-edge-connected spanning subgraphs where duplicate edges are allowed. Then we present a new greedy spanner construction for edge-w...
متن کاملApproximate Minimum 2-Connected Subgraphs in Weighted Planar Graphs
We consider the problems of finding the minimum-weight 2-connected spanning subgraph in edge-weighted planar graphs and its variations. We first give a PTAS for the problem of finding minimum-weight 2-edge-connected spanning subgraphs where duplicate edges are allowed. Then we present a new greedy spanner construction for edge-weighted planar graphs. From this we derive quasi-polynomial time ap...
متن کاملMinimum Weight 2-Edge-Connected Spanning Subgraphs in Planar Graphs
We present a linear time algorithm exactly solving the 2-edge connected spanning subgraph (2-ECSS) problem in a graph of bounded treewidth. Using this with Klein’s diameter reduction technique [15], we find a linear time PTAS for the problem in unweighted planar graphs, and the first PTAS for the problem in weighted planar graphs.
متن کاملMinimum Face-Spanning Subgraphs of Plane Graphs
A plane graph is a planar graph with a fixed embedding. Let G = (V,E) be an edge weighted connected plane graph, where V and E are the set of vertices and edges, respectively. Let F be the set of faces of G. For each edge e ∈ E, let w(e) ≥ 0 be the weight of the edge e of G. A face-spanning subgraph of G is a connected subgraph H induced by a set of edges S ⊆ E such that the vertex set of H con...
متن کاملApproximation Algorithms for k-Connected Graph Factors
Finding low-cost spanning subgraphs with given degree and connectivity requirements is a fundamental problem in the area of network design. We consider the problem of finding d-regular spanning subgraphs (or d-factors) of minimum weight with connectivity requirements. For the case of k-edge-connectedness, we present approximation algorithms that achieve constant approximation ratios for all d ≥...
