Description

Highly multimodal single-objective test function. The mathematical formula is given by

f(\mathbf{x}) = ∑_{i = 1}^{n - 1} (\mathbf{x}_i^2 + 2 \mathbf{x}_{i + 1}^2 - 0.3\cos(3π\mathbf{x}_i) - 0.4\cos(4π\mathbf{x}_{i + 1}) + 0.7)

with box-constraints \mathbf{x}_i \in [-100, 100] for i = 1, …, n. The multimodality will be visible by “zooming in” in the plot.
