Thanks Reza Ahmadzadeh for your suggestion. It's been a while since I uploaded these codes. I updated the files.

Dear Gilberto,
Thank you very much. Please, what about (1+1) CMA-ES. I think there is not a library for (1+1) CMA-ES
Best wishes

Actually in the main file you are doing double size of required function evaluations. You can move the fx=f(xkm1); before the while loop. and add fx=fy; inside the if statement after xkm1=y;
this way you evaluate each function as it many times that it needs not more.

Hello

sorry, in this code which variable represents optimal decision vector?
