Description

Multimodal single-objective test function. The implementation is based on the mathematical formulation

f(\mathbf{x}) = (\mathbf{x}_1 - \mathbf{x}_2)^2 + \exp((1 - \sin(\mathbf{x}_1))^2)\cos(\mathbf{x}_2) + \exp((1 - \cos(\mathbf{x}_2))^2)\sin(\mathbf{x}_1).

The function is restricted to two dimensions with \mathbf{x}_i \in [-2π, 2π], i = 1, 2.

Usage

1

Value

[smoof_single_objective_function]
