Options

The options are the number of discrete and continuous variables and an optional time delay for per evaluation.

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) = x12 + (x2 - 1)2 + x32 + ...

...

The Pareto front for the two-objective case is given in the following picture:
