说明：  该程序为完整的粒子群算法，粒子群算法，也称粒子群优化算法或鸟群觅食算法（Particle Swarm Optimization），缩写为 PSO， 是由J. Kennedy和R. C. Eberhart等开发的一种新的进化算法(Evolutionary Algorithm - EA)。PSO 算法属于进化算法的一种，和模拟退火算法相似，它也是从随机解出发，通过迭代寻找最优解。
(The program is a complete particle swarm algorithm, particle swarm optimization, also known as particle swarm optimization or bird swarm optimization, abbreviated as PSO, a new evolutionary algorithm developed by J. Kennedy and R. C. Eberhart (Evolutionary algorithm - EA). PSO algorithm belongs to evolutionary algorithm, which is similar to simulated annealing algorithm. It also starts from random solution and searches for the optimal solution through iteration.)
