Abstract: Constraint handling is one of the most difficult parts encountered in practical engineering design optimizations. Different kinds of methods were proposed for handling constraints namely, genetic algorithm, self-adaptive penalty approach and other evolutionary algorithms. Particle Swarm Optimization (PSO) efficiently solved most nonlinear optimization problems with inequity constraints. This study hybridizes PSO with a meta-heuristic algorithm called Tabu Search (TS) to solve the same engineering design problems. The algorithm starts with a population of particles or solution generated randomly and is updated using the update equations of PSO. The updated particles are then subjected to Tabu Search for further refinement. The PSO algorithm handles the global search for the solution while TS facilitates the local search. With embedded hyrbridization, this study which we call PSO-TS, showed better results compared to algorithms reported in Hu et al's study as applied!
to four benchmark engineering problems. Specifically, this study beat the results of Coello, Deb and Hu.
