Shekel function

Shekel function

Shekel function is a multidimensional, multimodal, continuous, deterministic function commonly used as a test function for testing optimization techniques.

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

f(underline{x}) = sum_{i = 1}^{m} frac{1}{c_{i} + sum_{j = 1}^{n} (x_{j} - a_{ji})^2 }
