改进的粒子群算法，有更好的性能，提高了算法的搜索能力(Improved particle swarm optimization, better performance, improved search ability of the algorithm)

说明：  详细用MATLAB程序编程灰狼算法，用于求密度函数的最优参数(MATLAB program programming grey Wolf algorithm, for density function to find the optimal parameters)

It is a matlab sourcecodes for the calculation of refrective index of AlGaAs alloy. I think it is useful for the guys who need the accurate value of the refrective index. It can be expanded to the other semiconductor alloy if you have the related parameters.
