The Weighted Set Covering Problem is a formal model for many practical optimization problems. In this problem the goal is to choose a subset of columns of minimal cost covering every row. Here, we present a novel application of the Artificial Bee Colony algorithm to solve the Weighted Set Covering Problem. The Artificial Bee Colony algorithm is a recent Swarm Metaheuristic technique based on the intel- ligent foraging behavior of honey bees. Experimental results show that our Artificial Bee Colony algorithm is competitive in terms of solution quality with other recent metaheuristic approaches.

Different solving methods have been pro- posed in the literature for the Weighted Set Covering Problem. Exact algorithms are mostly based on Branch-and-Bound and Branch-and-Cut techniques [2,15,4], Linear Programing and Heuristic methods [6]. However, these algorithms are rather time consuming and can only solve instances of very limited size. For this reason, many research efforts have been focused on the development of meta- heuristics to find as result good or near-optimal solutions within a reasonable period of time. An incomplete list of metaheuristics for the WSCP includes Genetic Algorithms [1,3], Simulated Annealing [5], Tabu Search [7], Cultural Al- gorithms [11,10] and Ant Colony Optimization [8]. For a deeper comprehension of most of the effective algorithms for the WSCP in the literature, we refer the C.
