griewank_func: Griewank Function

In EmiR: Evolutionary Minimizer for R

Griewank Function

Description

\loadmathjax

Implementation of n-dimensional Griewank function.

Usage

griewank_func(x)

Arguments

x	numeric or complex vector.

Details

On an n-dimensional domain it is defined by

\mjdeqn

f(\vecx) = 1 + \sum_i=1^n \fracx_i^24000 - \prod_i=1^n\cos\left(\fracx_i\sqrti\right),f(x) = 1 + \sum_i=1^n \fracx_i^24000 - \prod_i=1^ncos(\fracx_i\sqrti), and is usually evaluated on \mjeqnx_i \in [ -600, 600 ]x_i in [-600, 600], for all \mjeqni=1,...,ni=1,...,n. The function has global minima at \mjeqnf(\vecx) = 0f(x) = 0 for \mjeqnx_i=0x_i = 0 for all \mjeqni=1,...,ni=1,...,n.

Value

The value of the function.
