Cross-in-Tray Function

Description:

Dimensions: 2

The Cross-in-Tray function has multiple global minima. It is shown here with a smaller domain in the second plot, so that its characteristic "cross" will be visible.

Input Domain:

The function is usually evaluated on the square x_i ∈ [-10, 10], for all i = 1, 2.

Global Minima:
