An Improved Harmony Search Algorithms Based on Particle Swarm Optimizer

An improved harmony search algorithms based on particle swarm optimizer (HSPSO) is presented. The new heuristic optimization algorithm hybridizes HS and PSO, and it is based on the principles of those two methods with some differences. Comparisons with improved HS (IHS) , PSO algorithm (PSO), and it variants on a set of benchmark functions indicate that the HSPSO is capable of alleviating the problems of premature convergence.
