1.5 Rastrigin's function 6

Rastrigin's function is based on function 1 with the addition of cosine modulation to produce many local minima. Thus, the test function is highly multimodal. However, the location of the minima are regularly distributed.

function definition

f6(x)=10·n+sum(x(i)^2-10·cos(2·pi·x(i))), i=1:n;
-5.12<=x(i)<=5.12.

global minimum

f(x)=0; x(i)=0, i=1:n.

This function is implemented in objfun6.
