Griewank Function

Description

Highly multimodal function with a lot of regularly distributed local minima. The corresponding formula is:

f(\mathbf{x}) = ∑_{i=1}^{n} \frac{\mathbf{x}_i^2}{4000} - ∏_{i=1}^{n} \cos≤ft(\frac{\mathbf{x}_i}{√{i}}\right) + 1

subject to \mathbf{x}_i \in [-100, 100], i = 1, …, n.

Usage

1

Arguments
