Tournament Selection

Description

The best one is selected in the group consisting of t individuals selected by random sampling with or without replacement from the current population (Smith et.al, 1991).

Usage

seltour(fitvals, ns, selt, reptype, ...)

Arguments

fitvals	Vector of fitness values belonging to individuals
ns	Number of individuals to be selected
selt	Number of tournament size
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.

fitvals = c(6, -1, 2, 4, 5)            # Fitness values
cnames = paste0("C",1:length(fitvals)) # Chromosome names
matpool = seltour(fitvals, selt=selt)
cat(cnames[matpool],"\n")
