边支配集的参数化新算法

New parameterized algorithms for edge dominating set

Mingyu Xiao, Ton Kloks, Sheung-Hung Poon

摘要:

图G=(V,E)的边支配集是图G中的边的子集M,使得E-M中的每条边与M中的至少一条边关联。在参数化边支配集问题的一个例子中,我们给定一个图G=(V,E)和一个整数k,我们被要求决定G是否有一个大小不超过k的边支配集。本文证明了参数化边支配集控制问题可以在O^*(2.3147^k)时间和多项式空间中求解。我们证明了这个问题可以归结为一个具有O(k^3)边的二次核。

英文摘要:

An edge dominating set of a graph G=(V,E) is a subset M of edges in the graph such that each edge in E-M is incident with at least one edge in M. In an instance of the parameterized edge dominating set problem we are given a graph G=(V,E) and an integer k and we are asked to decide whether G has an edge dominating set of size at most k. In this paper we show that the parameterized edge dominating set problem can be solved in O^*(2.3147^k) time and polynomial space. We show that this problem can be reduced to a quadratic kernel with O(k^3) edges.
