Module Description
Multi-Objective Sphere
The multi-objective sphere function f is a set of quadratic functions. More precisely, each fi is computed as the square of all continuous variables.
fi(x) = (xi - 1)2 + sumj, j~=i (xj2)
For example f1(x) = (x1 - 1)2 + x22 + x32 + ... f2(x) = x1 2 + (x2 - 1)2 + x32 + ... ...
