Abstract: An new chaotic simplified particle swarm optimization algorithm based on logistic mapping (CIW-SPSO) is proposed to tackle the problems of basic PSO algorithm, such as easy to fall into local optimum, slow convergence, and low accuracy. The algorithm introduces chaos theory make inertia weight with chaotic search ability, and make learning factor changing with sine function optimization process, reduce the probability of algorithm falling into local optimum. Six classical test functions are used for simulation. The results show that the CIW-SPSO algorithm has faster convergence speed and higher accuracy, and can avoid local optimum and improve the algorithm optimization performance effectively.
