makeGriewankFunction

Highly multimodal function with a lot of regularly distributed local minima.
The corresponding formula is:
$$f(\mathbf{x}) = \sum_{i=1}^{n} \frac{\mathbf{x}_i^2}{4000} - \prod_{i=1}^{n} \cos\left(\frac{\mathbf{x}_i}{\sqrt{i}}\right) + 1$$
subject to $\mathbf{x}_i \in [-100, 100], i = 1, \ldots, n$.

Provides generators for a high number of both single- and multi-
objective test functions which are frequently used for the benchmarking of
(numerical) optimization algorithms. Moreover, it offers a set of convenient
functions to generate, plot and work with objective functions.
