Hartmann 4-Dimensional Function


Description:

Dimensions: 4

The 4-dimensional Hartmann function is multimodal. It is given here in the form of Picheny et al. (2012), having a mean of zero and a variance of one. The authors also add a small Gaussian error term to the output.

Input Domain:

The function is evaluated on the hypercube xi ∈ [0, 1], for all i = 1, 2, 3, 4.
