nsga_Crossover {rmoo}

Crossover operators in non-dominated genetic algorithms

Description

Functions implementing crossover non-dominated genetic operator.

Usage

  nsga_spCrossover(object, parents)

  nsgabin_spCrossover(object, parents)

  nsgareal_spCrossover(object, parents)
  nsgareal_sbxCrossover(object, parents, nc = 20)

  nsgaperm_oxCrossover(object, parents)

Arguments

object

An object of class "nsga", "nsga2" and "nsga3", usually resulting from a call to function nsga, nsga2 and nsga3.

parents

A two-rows matrix of values indexing the parents from the current population.

nc

Parameters of non-dominated 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.
