Crossover operators in genetic algorithms

Description

Functions implementing crossover genetic operator.

Usage

ga_spCrossover(object, parents, ...)

gabin_spCrossover(object, parents, ...)
gabin_uCrossover(object, parents, ...)

gareal_spCrossover(object, parents, ...)
gareal_waCrossover(object, parents, ...)
gareal_laCrossover(object, parents, ...)
gareal_blxCrossover(object, parents, a = 0.5, ...)
gareal_laplaceCrossover(object, parents, a = 0, b = 0.15, ...)

gaperm_cxCrossover(object, parents, ...)
gaperm_pmxCrossover(object, parents, ...)
gaperm_oxCrossover(object, parents, ...)
gaperm_pbxCrossover(object, parents, ...)

Arguments

object	An object of class "ga", usually resulting from a call to function ga.
parents	A two-rows matrix of values indexing the parents from the current population.
...	Further arguments passed to or from other methods.
a, b	Parameters of genetic operators.

Value

Return a list with two elements:

children	a matrix of dimension 2 times the number of decision variables containing the generated offsprings;
fitness	a vector of length 2 containing the fitness values for the offsprings. A value NA is returned if an offspring is different (which is usually the case) from the two parents.
