说明：  粒子群算法（PSO）源代码工具箱。该工具箱将PSO算法的核心部分封装起来，提供给用户的为算法的可调参数，用户只需要定义好有关参数，即可自行优化。
(Particle Swarm Optimization (PSO) source code toolbox. The toolkit will be the core of the PSO algorithm package, and available to users of the adjustable parameters for the algorithm, users only need to define the relevant parameters, can be self-optimizing.)
