Shubert Function


Description:

Dimensions: 2

The Shubert function has several local minima and many global minima. The second plot shows the the function on a smaller input domain, to allow for easier viewing.

Input Domain:

The function is usually evaluated on the square xi ∈ [-10, 10], for all i = 1, 2, although this may be restricted to the square xi ∈ [-5.12, 5.12], for all i = 1, 2.

Global Minimum:
