说明：  结合LPSO和GPSO的优点，该MATLAB程序实现一种时变参数的改进粒子群优化（IPSO） 算法。在IPSO中，粒子在向全局最优和局部最优粒子学习的同时，还向种群中最优粒子学习，因此具有较强的全局寻优能力。
(Combined with the advantages of LPSO and GPSO, the MATLAB program implements a modified particle swarm optimization (IPSO) algorithm with time-varying parameters. In IPSO, when the particle is learning the global optimum and the local optimal particle, it also has the ability of global optimization.)
