MutationRateFactory {xegaPopulation}

Configure the mutation rate function of a genetic algorithm.

Description

The MutationRateFactory() implements selection of one of the crossover rate functions in this package by specifying a text string. The selection fails ungracefully (produces a runtime error), if the label does not match. The functions are specified locally.

Current support:

1. "Const" returns ConstMRate() (Default).

2. "IV" returns IAMrate(). This function gives bad genes a higher mutation rate.

Usage

MutationRateFactory(method = "Const")

Arguments

method

A string specifying a function for the mutation rate.

Value

A mutation rate function.

Examples

f<-MutationRateFactory("Const")
f(10, list(MutationRate1=function() {0.2}))
