makeNaryFunctionFitnessFunction: Create a fitness function from a n-ary reference function

Description

Creates a fitness function that calculates an error measure with respect to an arbitrary n-ary reference function based sample points generated by a given designFunction. When an indsizelimit is given, individuals exceeding this limit will receive a fitness of Inf.

Usage

makeNaryFunctionFitnessFunction(func, dim, designFunction = gridDesign, errorMeasure = rmse, indsizelimit = NA, ...)

Arguments

func
The reference function. Its single argument must be numeric vector of length dim and it must return a scalar numeric.
dim
The dimension of the reference function.
designFunction
A function to generate sample points. Its first argument must be dim. Defaults to gridDesign.
errorMeasure
A function to use as an error measure, defaults to RMSE.
indsizelimit
Individuals exceeding this size limit will get a fitness of Inf.
...
Additional arguments to the designFunction.

Value

A fitness function based on the reference function func.
