6D sphere function
Description
6D Shifted and rotated weighted sphere test function.
Usage
sphere6(x)
Arguments
x |
a 6-dimensional vector specifying the location where the function is to be evaluated. |
Details
The 6D Shifted and rotated weighted sphere (standardized version) function
is here defined over the domain [0,1]^6
. It has 1 global minimizer :
x* = c(1,0.8,0.6,0.4,0.2,0), ), with minimum f(x*) = -1.941389. It has no
further local minima.
Value
A real number equal to the sphere6 function values at x
