Schwefel function
Description
Highly multimodal test function. The cursial thing about this function is, that the global optimum is far away from the next best local optimum. The function is computed via:
f(\mathbf{x}) = \sum_{i=1}^{n} -\mathbf{x}_i \sin\left(\sqrt(|\mathbf{x}_i|)\right)
with \mathbf{x}_i \in [-500, 500], i = 1, \ldots, n.
