In mathematics, the Griewank function is often used in testing of optimization. It is defined as follows:[1]
The following paragraphs display the special cases of first, second and third order Griewank function, and their plots.
First-order Griewank function
The first order Griewank function has multiple maxima and minima.[2]
Let the derivative of Griewank function be zero:
Find its roots in the interval [−100..100] by means of numerical method,
In the interval [−10000,10000], the Griewank function has 6365 critical points.
