Module Description

Multi-Objective Sphere

The multi-objective sphere function f is a set of quadratic functions. More precisely, each f_i is computed as the square of all continuous variables.

f_i(x) = (x_i - 1)² + sum_{j, j~=i} (x_j²)

For example

f₁(x) = (x₁ - 1)² + x₂² + x₃^{2 + ...}

f₂(x) = x₁² + (x₂ - 1)² + x₃^{2 + ...}

...

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