makeSixHumpCamelFunction function

Three-Hump Camel Function

Two dimensional single-objective test function with six local minima oh which two are global. The surface is similar to the back of a camel. That is why it is called Camel function. The implementation is based on the formula: [REMOVE_ME]$f(\mathbf{x}) = \left(4 - 2.1\mathbf{x}_1^2 + \mathbf{x}_1^{0.75}\right)\mathbf{x}_1^2 + \mathbf{x}_1 \mathbf{x}_2 + \left(-4 + 4\mathbf{x}_2^2\right)\mathbf{x}_2^2 [REMOVE_ME_2]$

with box constraints $\mathbf{x}_1 \in [-3, 3]$ and $\mathbf{x}_2 \in [-2, 2]$.
