Description

A modified version of the Rastrigin function following the formula:

f(\mathbf{x}) = ∑_{i=1}^{n} 10≤ft(1 + \cos(2π k_i \mathbf{x}_i)\right) + 2 k_i \mathbf{x}_i^2.

The box-constraints are given by \mathbf{x}_i \in [0, 1] for i = 1, …, n and k is a numerical vector. Deb et al. (see references) use, e.g., k = (2, 2, 3, 4) for n = 4. See the reference for details.
