select: Universal selection high-level function

In drizztxx/gatbxr: Genetic Algorithm Toolbox Implemented by R

Description

This function performs universal selection. The function handles multiple populations and calls the low level selection function for the actual selection process.

Usage

select(SEL_F=c("sus","rws"),Chrom,FitnV,GGAP=1,SUBPOP=1,...)

Arguments

SEL_F	character string indicating the selection function.
Chrom	a matrix containing the individuals (parents) of the current population. Each row corresponds to one individual.
FitnV	a vector containing the fitness values of the individuals in the population.
GGAP	an optional number indicating rate of individuals to be selected. Default is set to 1.
SUBPOP	an optional number indicating subpopulations. Default is set to 1 subpopulation.
...	ohter aurguments passed on to selection function.

Value

a matrix containing the selected individuals.

The original matlab implementation of mutate was written by Hartmut Pohlheim. The R implementation was written by David Zhao.

Examples

Chrom = crtbp(40,10)$Chrom

#Ojbective function is the sum of individuals
FitnV = ranking(apply(Chrom,1,sum))

Selch = select(SEL_F="sus",Chrom=Chrom,FitnV=FitnV,GGAP=0.9)
