二维粒子群算法的matlab源程序，注释很详细，主要求解函数的极大、极小值。-Two dimensional particle swarm algorithm matlab source, annotation is very detailed, mainly to solve the function of the maximum and minimum.

使用粒子群优化算法实现函数最优值的求解，并对参数进行优化。(The particle swarm optimization algorithm is used to solve the optimal value of the function, and the parameters are optimized.)
