Rastrigin Function
Description
One of the most popular single-objective test functions consists of many local optima and is thus highly multimodal with a global structure. The implementation follows the formula
f(\mathbf{x}) = 10n + \sum_{i=1}^{n} \left(\mathbf{x}_i^2 - 10 \cos(2\pi \mathbf{x}_i)\right).
The box-constraints are given by \mathbf{x}_i \in [-5.12, 5.12]
for
i = 1, \ldots, n
.
