Two New Upper Bounds for the Maximum k-plex Problem

Jiongzhi Zheng, Mingming Jin, Kun He

A k-plex in a graph is a vertex set where each vertex is non-adjacent to at most k vertices (including itself) in this set, and the Maximum k-plex Problem (MKP) is to find the larg…

Incorporating Multi-armed Bandit with Local Search for MaxSAT

Jiongzhi Zheng, Kun He, Jianrong Zhou +3

Partial MaxSAT (PMS) and Weighted PMS (WPMS) are two practical generalizations of the MaxSAT problem. In this paper, we propose a local search algorithm for these problems, called…

A memetic algorithm for the minimum sum coloring problem

Yan Jin, Jin-Kao Hao, Jean-Philippe Hamiez

Given an undirected graph , the Minimum Sum Coloring problem (MSCP) is to find a legal assignment of colors (represented by natural numbers) to each vertex of such that the…
