粒子群算法是一种进化计算技术，来源于对鸟群捕食的思考,最早由Kenney与Eberhart

于1995年提出。在PSO中，寻找最优解被看做群体寻找目标。个体在搜索的过程中具有自己的位置和搜索速度。个体追寻最优个体在解空间中进行搜索。搜索的过程是一个反复的迭代过程。在这个过程中，个体完成的任务一是找寻自己认可的最优解；另个任务是获知群体得到的暂时最优解。

-The particle swarm optimization is an evolutionary computation technique, derived from the thinking of the birds of prey, was first proposed by Kenney and Eberhart in 1995. PSO, to find the optimal solution is seen as a group to find the target.The individual has its own position in the search process and search speed. The individual pursuit of the best individual in the solution space to search. The search process is an iterative process repeated. In this process, individuals complete the task first, find the optimal solution to themselves　another task is informed groups of temporary optimal solution.
