Description Usage Value References


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.
