Multi-Objective Particle Swarm Optimization Based on Self-Update and Grid Strategy

A multi-objective particle swarm optimization based on self-update and grid strategy was proposed for improving the function of Pareto set. The method chooses \( pBest \) with self-update strategy, uses grid method as the selection mode of \( gBest \). It is tested to compare with the performance of the optimal solution’s evaluation and selection. The results show that algorithm has gained better convergence with even distributing and diversity of Pareto set.
