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，它也是通过适应度来评价解的品质-PSO algorithm is a kind of evolutionary algorithms，Similar and simulated annealing algorithm，It is also starting　the random solution，To find the optimal solution by iteration，It is also through the fitness to　uate the quality of the solution
