粒子群优化算法（Particle Swarm Optimization，简称为PSO），粒子群算法是近年来发展起来的一种新的进化算法，和遗传算法相似，它也是从随机解出发，通过迭代寻找最优解，通过适应度来评价解的品质(Particle swarm optimization algorithm (Particle Swarm Optimization, referred to as PSO), particle swarm algorithm is a new evolutionary algorithm developed in recent years, similar to genetic algorithm, it is also from the random equation through iterative search for the optimal solution, the fitness to evaluate the quality of the solution)
