nsga_Selection function

Selection operators in non-dominated genetic algorithms

Functions implementing selection non-dominated genetic operator.

nsga_lrSelection(object, r, q)
  nsga_tourSelection(object, k = 3, ...)

  nsgabin_lrSelection(object, r, q)
  nsgabin_tourSelection(object, k = 3, ...)

  nsgareal_lrSelection(object, r, q)
  nsgareal_tourSelection(object, k = 3, ...)

  nsgaperm_lrSelection(object, r, q)
  nsgaperm_tourSelection(object, k = 3, ...)

Arguments

• object: An object of class "nsga", "nsga2" or "nsga3", usually resulting from a call to function nsga, nsga2 or nsga3.
• r: A tuning parameter for the specific selection operator.
• q: A tuning parameter for the specific selection operator.
• k: A tuning parameter for the specific selection operator.
• ...: Further arguments passed to or from other methods.

Returns

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.
