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

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)
