In this paper, an improved Multi-Modal Optimization (MMO) algorithm, called LSEPSO, has been proposed. LSEPSO combined Electrostatic Particle Swarm Optimization (EPSO) algorithm and a local search method and then made some modification on them. It has been shown to improve global and local optima finding ability of the algorithm. This algorithm used a modified local search to improve particle's personal best, which used n-nearest-neighbor instead of nearest-neighbor. Then, by creating n new points among each particle and n nearest particles, it tried to find a point which could be the alternative of particle's personal best. This method prevented particle's attenuation and following a specific particle by its neighbors.
