A Stochastic Local Search Approach to Vertex Cover

Abstract: Abstract. We introduce a novel stochastic local search algorithm for the vertex cover problem. Compared to current exhaustive search techniques, our algorithm achieves excellent performance on a suite of problems drawn from the field of biology. We also evaluate our performance on the commonly used DIMACS benchmarks for the related clique problem, finding that our approach is competitive with the current best stochastic local search algorithm for finding cliques. On three very large problem instances, our algo… Show more

“…According to the reported results, the overall performance of these heuristics are not competitive compared with recent local search methods. Finally, it is worthwhile to mention that some recent edge weighting local search approaches for the equivalent minimum vertex cover problem, such as COVER (Richter, Helmert, & Gretton, 2007) and EWCC (Cai, Su, & Sattar, 2011), report very good results on the DIMACS and BHOSLIB benchmarks.…”
