Chaotic hybrid particle swarm optimization algorithm based on Tent map

Aiming to improve the performance of standard particle swarm optimization algorithm,a new method-chaotic hybrid particle swarm optimization(CHPSO) algorithm is introduced through the technique of algorithm hybrid.By integrating eugenic strategy and chaotic optimization into particle swarm optimization algorithm,it greatly enhances the local searching efficiency and global searching performance.Furthermore,the particles are divided into two classes and perform different operations to co-evolve.Simulation results on standard test functions show that CHPSO is pretty efficient to solve high dimensional complex problems.It has high optimization efficiency,good global performance,and stable optimization outcomes.The performance of CHPSO is evidently better than PSO and SGA.
