说明：  粒子群优化算法的基本思想是通过群体中个体之间的协作和信息共享来寻找最优解． PSO的优势在于简单容易实现并且没有许多参数的调节。目前已被广泛应用于函数优化、神经网络训练、模糊系统控制以及其他遗传算法的应用领域。
(The basic idea of Particle Swarm Optimization (PSO) is to find the optimal solution by cooperating and sharing information among individuals. The advantage of PSO is that it is simple and easy to implement and does not have many parameters to adjust. Has been widely used in function optimization, neural network training, fuzzy system control and other genetic algorithm applications.)
