ga_Selection: Selection operators in genetic algorithms

Description

Functions implementing selection genetic operator.

Usage

ga_lrSelection(object, r = 2/(object@popSize * (object@popSize - 1)),
                       q = 2/object@popSize, …)
ga_nlrSelection(object, q = 0.25, …)
ga_rwSelection(object, …)
ga_tourSelection(object, k = 3, …)

gabin_lrSelection(object, r = 2/(object@popSize * (object@popSize - 1)), q = 2/object@popSize, …) gabin_nlrSelection(object, q = 0.25, …) gabin_rwSelection(object, …) gabin_tourSelection(object, k = 3, …)

gareal_lrSelection(object, r = 2/(object@popSize * (object@popSize - 1)), q = 2/object@popSize, …) gareal_nlrSelection(object, q = 0.25, …) gareal_rwSelection(object, …) gareal_tourSelection(object, k = 3, …) gareal_lsSelection(object, …) gareal_sigmaSelection(object, …)

gaperm_lrSelection(object, r = 2/(object@popSize * (object@popSize - 1)), q = 2/object@popSize, …) gaperm_nlrSelection(object, q = 0.25, …) gaperm_rwSelection(object, …) gaperm_tourSelection(object, k = 3, …)

gareal_de(object, F = 0.8, p = 0.5, …)

Arguments

object

An object of class "ga", usually resulting from a call to function ga.

r

A tuning parameter for the GA selection operator.

q

A tuning parameter for the GA selection operator.

k

A tuning parameter for the GA selection operator.

F, p

Tuning parameters for the DE selection operator.

Further arguments passed to or from other methods.

Value

Return a list with two elements:

population

a matrix of dimension object@popSize times the number of decision variables containing the selected individuals or strings;

fitness

a vector of length object@popSize containing the fitness values for the selected individuals.
