1.3 Rotated hyper-ellipsoid function

An extension of the axis parallel hyper-ellipsoid is Schwefel's function1.2. With respect to the coordinate axes, this function produces rotated hyper-ellipsoids. It is continuos, convex and unimodal.

function definition

f1b(x)=sum(sum(x(j)^2), j=1:i), i=1:n;
-65.536<=x(i)<=65.536.

global minimum

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

This function is implemented in objfun1b.
