seltour2: Tournament Selection 2

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

Tournament Selection 2

Description

Each individual is given a chance to participate in the tournament at least once in selection by tournament in this function. For this reason, individuals participating in the tournament cannot participate in another tournament, but after the tournament of all individuals is completed, they can get a chance to participate in another tournament (Nicolau, 2009).

Usage

seltour2(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.

Examples

selt = 2                    # Size of tournament
fitvals = c(6, -1, 2, 4, 5) # Fitness values
cnames = paste0("C",1:length(fitvals)) # Chromosome names
matpool = seltour2(fitvals, selt=selt)
cat(cnames[matpool],"\n")
