Description

Unimodal function with its global optimum in the center of the search space. The attraction area of the global optimum is very small in relation to the search space:

f(\mathbf{x}) = -\cos(\mathbf{x}_1)\cos(\mathbf{x}_2)\exp≤ft(-≤ft((\mathbf{x}_1 - π)^2 + (\mathbf{x}_2 - pi)^2\right)\right)

with \mathbf{x}_i \in [-100, 100], i = 1,2.
