This study presents the Malatya vertex-cover algorithm, which provides an efficient solution and a robust approach based on the Malatya centrality value algorithm for MVCP. Although MVCP is an NP-complete problem that cannot be solved in polynomial time, the proposed meth...

Now we need to prove that it's exactly of maximum matching size, therefore we need to show a correct algorithm that's given a maximum matching, is able to construct a vertex cover of the same size as the matching. Going by the same logic, then, for each edge in the maximum matching,...
问题描述:就是在图中找最小的点集,使得覆盖所有边。 和独立集等价:独立集问题:在图中找最大的点集,使得点集内的所有点互不相连。 引理:顶点覆盖集和独立集互补。 上面这个引理使得这两个问题可以相互规约,从而这两个问题等价。 等价问题:给定图G和数k, 问G包含大小至少为k的独立集吗? 为什么等价:如果我们能...
heuristic algorithmMinimum vertex cover problem(Min-VC) on a graph is a NP-hard problem. The neighborhoods of a vertex are analyzed in this paper, and so are the information they hold for judging whether the vertex is belong to Min-VC or not. Then, the concept of Max-I share degree ...

The first algorithm EWLS is an iterated local search algorithm that works with a partial vertex cover, and utilizes an edge weighting scheme which updates edge weights when getting stuck in local optima. Nevertheless, EWLS has an instance-dependent parameter. Further, we propose a strategy called ...
