二部图最大$k$ -点覆盖的0.821-比率纯组合算法

Edouard Bonnet, Bruno Escoffier, Vangelis Paschos, Georgios Stamoulis

摘要:

我们在本文中的目标是提出一个\textit{combinatorial algorithm},击败了唯一这样的算法,贪婪的。我们研究了多项式近似的最大顶点覆盖问题的二分图的纯组合算法,并提出了一个计算机辅助分析,发现最坏情况下的近似保证,是有界的~0.821。

英文摘要:

Our goal in this paper is to propose a \textit{combinatorial algorithm} that beats the only such algorithm known previously, the greedy one. We study the polynomial approximation of the Maximum Vertex Cover Problem in bipartite graphs by a purely combinatorial algorithm and present a computer assisted analysis of it, that finds the worst case approximation guarantee that is bounded below by~0.821.
