摘要
针对基本粒子群优化(Particle Swarm Optimization,PSO)算法的不足,提出动态惯性权重粒子群优化算法,其惯性系数随算法进化而动态减少。仿真结果验证了该改进算法的有效性:算法的收敛速度比基本PSO算法的收敛速度快;同时,算法得到的最优解比基本PSO算法好。
An improved particle swarm optimization algorithm(IPSO) is proposed to improve the performance of standard PSO.The dynamic inertia weight is introduced in IPSO and its value decreases with iterative generation increasing.The algorithm is validated with a set of 6 benchmark functions and compared with standard PSO.Experiment results indicate that the IPSO improves the optimization performance on the benchmark functions significantly.
