makeDeflectedCorrugatedSpringFunction

Scalable single-objective test function based on the formula
$$f(\mathbf{x}) = 0.1 \sum_{i = 1}^{n} (x_i - \alpha)^2 - \cos\left(K \sqrt{\sum_{i = 1}^{n} (x_i - \alpha)^2}\right)$$
with $\mathbf{x}_i \in [0, 2\alpha], i = 1, \ldots, n$ and $\alpha = K = 5$
by default.

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.
