چکیده

We present a distributed 2-approximation algorithm for the minimum vertex cover problem. The algorithm is deterministic, and it runs in (∆+ 1) synchronous communication rounds, where ∆ is the maximum degree of the graph. For ∆ = 3, we give a 2-approximation algorithm also for the weighted version of the problem.

Improved Approximation Algorithm for the Combination of Parallel Machine Scheduling and Vertex Cover

This paper studies a combination of parallel machine scheduling and the vertex cover problem. Given some weighted vertices in an undirected graph, a set of vertices is called a vertex cover if for each edge at least one endpoint belongs to this set. Our problem is to schedule a set of weighted vertices on m identical parallel machines such that the set of vertices is a vertex cover and the make...

Vertex Cover in Graphs with Locally Few Colors

In [13], Erdős et al. defined the local chromatic number of a graph as the minimum number of colors that must appear within distance 1 of a vertex. For any ∆ ≥ 2, there are graphs with arbitrarily large chromatic number that can be colored so that (i) no vertex neighborhood contains more than ∆ different colors (bounded local colorability), and (ii) adjacent vertices from two color classes indu...

A 2-approximation NC algorithm for connected vertex cover and tree cover

The connected vertex cover problem is a variant of the vertex cover problem, in which a vertex cover is additional required to induce a connected subgraph in a given connected graph. The problem is known to be NP-hard and to be at least as hard to approximate as the vertex cover problem is. While several 2-approximation NC algorithms are known for vertex cover, whether unweighted or weighted, n...

Distributed Vertex Cover in Network Graphs

Vertex cover, a minimal set of nodes to cover all edges in a graph, is an abstraction of coverage problems in sensor networks, transportation networks, etc, and is a well-konwn NP-hard problem. Minimum weighted vertex cover (MWVC) problem asks for further minimizing the cumulative weight of a vertex cover. We present new distributed k-hop algorithms for MWVC problem with theoretical and practic...

A 2-Approximation Algorithm for the Undirected Feedback Vertex Set Problem

A feedback vertex set of a graph is a subset of vertices that contains at least one vertex from every cycle in the graph. The problem considered is that of finding a minimum feedback vertex set given a weighted and undirected graph. We present a simple and efficient approximation algorithm with performance ratio of at most 2, improving previous best bounds for either weighted or unweighted case...
