A memetic algorithm for the weighted feedback vertex set problem
Abstract
Given an undirected and vertex weighted graph , the Weighted Feedback Vertex Set Problem consists of finding the subset
of vertices, with minimum weight, whose removal results in an acyclic graph. Finding the minimum feedback vertex set in a graph is an important combinatorial problem that has a variety of real applications. In this article, we introduce a memetic algorithm for this problem. We propose an efficient greedy procedure that quickly generates chromosomes with specific characteristics and a wise application of recent local search procedures based on k-diamonds. Computational results show that the proposed algorithm outperforms the effectiveness of two other metaheuristics recently proposed in the literature for this problem. © 2014 Wiley Periodicals, Inc.
