select {adana}

Select parents for the mating pool

Description

The select function is a function that wraps all parent selection algorithms. It is coded for call purposes from adana main function.

Usage

select(selfunc, fitvals, ns, selb, selbc,
                  selc, selk, sells, selns, selps, sels, selt, 
                  selt0, selw, selg, selgmax, fmin, reptype, ...)

Arguments

selfunc

Name of selection function

fitvals

Vector of fitness values belonging to individuals

ns

Number of individuals to be selected

selb

Exponent coefficent, (selb >= 0.0)

selbc

Base of exponent

selc

Scaling parameter

selk

Power factor

sells

Scaling factor

selns

Number of Selection pressure

selps

Percentage of Selection, (0.0 <= selps <= 1.0)

sels

Selection pressure, (1.0 <= sels <= 2.0)

selt

Number of tournament size

selt0

Number, Initial temperature

selw

Number, Window Size

selg

Current generation number

selgmax

Maximum generation number

fmin

The number to subtract from all fitness values.

reptype

Type of Sampling, TRUE : without repetitions, FALSE : with repetitions

...

Further arguments passed to or from other methods.

Value

The indices of randomly selected individuals are returned.

Examples

# Create population
population = initialize(initfunc=initbin, n=10, m=8)
head(population, 5)
# Calculate fitness values
m = ncol(population)-2
fitvals = evaluate(maxone, population[,1:m])
population[,"fitval"] = fitvals
head(population, 5)
# Select parents by RWS
selidx = select(selfunc=selrws, fitvals=fitvals)
matpool = population[selidx,]
head(matpool, 5)
# Selected chromosomes
table(rownames(matpool))
