很实用的群优化智能算法，计算粒子群算法的源代码，所需优化的目标函数命名为fitness即可。-a partical swarm algorithm

Particle swarm optimization (PSO) is a population based stochastic optimization technique developed by Dr. Eberhart and Dr. Kennedy in 1995, inspired by social behavior of bird flocking or fish schooling. Each particle keeps track of its coordinates

根据机器人工作空间，利用粒子群算法计算关节型机器人各个机械臂尺寸，包含了目标函数，适应度函数等(According to the robot workspace, the particle swarm algorithm (PSO) is used to calculate the dimensions of each robot arm, including the objective function and the fitness function)
