This paper presents a novel algorithm named HPSODE for constrained optimization problems. The proposed algorithm integrates particle swarm optimization (PSO) with differential evolution (DE) on the basis of an optimal information sharing mechanism firstly, which avoids premature convergence defects of the single algorithm. Then under the guidance of the feasibility rules, the algorithm quickly finds better feasible solution. Finally, HPSODE is tested on two engineering design problems. Comparisons show that HPSODE has higher computational precision, better robustness and is more effective for solving constrained optimization problem.
