schwefel_func: Schwefel Function

In EmiR: Evolutionary Minimizer for R

Schwefel Function

Description

\loadmathjax

Implementation of n-dimensional Schwefel function.

Usage

schwefel_func(x)

Arguments

x	numeric or complex vector.

Details

On an n-dimensional domain it is defined by

\mjdeqn

f(\vecx) = \sum_i=1^n \left[ -x_i\sin(\sqrt|x_i|) \right],f(x) = sum_1^n [ -x_i*sin(sqrt(|x_i|) ], and is usually evaluated on \mjeqnx_i \in [ -500, 500 ]x_i in [-500, 500], for all \mjeqni=1,...,ni=1,...,n. The function has one global minimum at \mjeqnf(\vecx) = -418.9829nf(x) = -418.9829n for \mjeqnx_i=420.9687x_i=420.9687 for all \mjeqni=1,...,ni=1,...,n.

Value

The value of the function.
