sellrs3: Linear Ranking Selection 3

In adana: Adaptive Nature-Inspired Algorithms for Hybrid Genetic Optimization

Linear Ranking Selection 3

Description

The LRS operator selects through probabilities obtained using ordered numbers according to their fitness values. In this algorithm, the selection pressure can be adjusted with the s parameter.

Usage

sellrs3(fitvals, ns, sels, ...)

Arguments

fitvals	Vector of fitness values belonging to individuals
ns	Number of individuals to be selected
sels	Selection pressure, (1.0 <= sels <= 2.0)
...	Further arguments passed to or from other methods.

Value

The indices of randomly selected individuals are returned.

Examples

fitvals = c(6.1, 3.5, 6.2, 4.4, 5.2)
cnames = paste0("C",1:length(fitvals)) 
matpool = sellrs3(fitvals)
cat(cnames[matpool],"\n")
matpool = sellrs3(fitvals, sels=2)
cat(cnames[matpool],"\n")
