In this paper we present a novel local search for improving the ability of multiobjective evolutionary algorithms when finding repeated patterns -motifs- in DNA sequences. In the metaheuristic design, two competing goals must be taken into account: exploration and exploitation. Exploration is needed to cover most of the optimization problem search space and provide a reliable estimation of the global optimum. In turn, exploitation is also important since normally the solutions refinement allows the achievement of better results. In this work we take advantage of both concepts by combining the exploration capabilities of a population-based evolutionary algorithm and the power of a local search, especially designed to optimize the Motif Discovery Problem (MDP). For doing this, we have implemented a new hybrid multiobjective metaheuristic based on Artificial Bee Colony (ABC). After analyzing the results achieved by this algorithm, named Hybrid-MOABC (H-MOABC), and comparing them with those achieved by three multiobjective evolutionary algorithms and thirteen well-known biological tools, we prove that the hybridization computes accurate biological predictions on real genetic instances in an optimum way. In fact, to the best of our knowledge, the results presented in this paper improve those presented in the literature.
