Abstract: An improved particle swarm optimization algorithm (CRPSO) is proposed to improve the premature convergence of particle swarm optimization algorithm (PSO). The particles of basic PSO are called as main particles in the improved algorithm. When the improved algorithm finds a better globally optimal extreme value point, it produces several points named resident particles around the global optimization point. The two kinds of particles work in cooperation that main particles are responsible for global research and resident particles for local search. Resident particles will help main particles to avoid falling into local extremum easily and improve the diversity of the whole particle swarm. The simulation results have validated its feasibility and effectiveness.

Key words: PSO, premature convergence, main particles, resident particles
