Abstract. Many interesting results that improve on the exponential running times of exact algorithms for NP-hard problems have been obtained in recent years.

One example that has attracted quite some at- tention of late is t-Vertex Cover, the problem of finding k nodes that cover at least t edges in a graph.

Nov 21, 2024 · In this paper we study partial cover problems defined on graphs namely Partial Vertex Cover and Partial r-Dominating Set from the view point of ...

Dec 5, 2017 · Vertex Cover: We begin by showing that there is an approximation algorithm for vertex cover with a ratio bound of 2, that is, this algorithm ...

In the optimization version of VERTEX-COVER, we are given as input an undirected graph G and the output is a vertex cover of minimum size. We refer to this ...

An unweighted vertex cover algorithm will never k-approximate a minimal weighted vertex cover. Unweighted algorithms behave as if all vertices have the same ...

Nov 3, 2012 · Intuitively, vertices in T are added if they are in R and subtracted if they are in L to obtain the minimum vertex cover. Thus, the Hopcroft– ...

Apr 23, 2021 · Abstract. In the classical partial vertex cover problem, we are given a graph G and two positive integers.

While intuitive, the algorithm actually performs poorly on many classes of graphs and has no fixed performance bounds. An alternative algorithm is focused on ...
