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?

The implementation is very straightforward and good based on my opinion. However, the program becomes slow when tested by n_x=30, mu=lambda=100 after a few hundred generations. This may be the problem of Evolutionary Strategy itself not the implementation.
