Shekel function

From Wikipedia, the free encyclopedia
(Redirected from Shekel's foxholes)
A Shekel function in 2 dimensions and with 10 maxima

The Shekel function or also Shekel's foxholes is a multidimensional, multimodal, continuous, deterministic function commonly used as a test function for testing optimization techniques.[1]

The mathematical form of a function in dimensions with maxima is:

or, similarly,

Global minima

[edit]

Numerically certified global minima and the corresponding solutions were obtained using interval methods for up to .[2]
