Genetic::OpSelection(3User Contributed Perl DocumentatiGenetic::OpSelection(3)

NAME
       AI::Genetic::OpSelection	- A class that implements various selection
       operators.

SYNOPSIS
       See AI::Genetic.

DESCRIPTION
       This package implements a few selection mechanisms that can be used in
       user-defined strategies.	The methods in this class are to be called as
       static class methods, rather than instance methods, which means you
       must call them as such:

	 AI::Genetic::OpSelection::MethodName(arguments)

SELECTION OPERATORS AND	THEIR METHODS
       The following selection operators are defined:

       Roulette	Wheel
	   Here, the probability of an individual being	selected is
	   proportional	to its fitness score. The following methods are
	   defined:

	   initWheel(population)
	       This method initializes the roulette wheel. It expects an
	       anonymous list of individuals, as returned by the people()
	       method as described in "CLASS METHODS" in AI::Genetic.  This
	       must be called only once.

	   roulette(?N?)
	       This method selects N individuals. N defaults to	2. Note	that
	       the same	individual can be selected multiple times.

	   rouletteUnique(?N?)
	       This method selects N unique individuals. N defaults to 2. Any
	       individual can be selected only once per	call to	this method.

       Tournament
	   Here, N individuals are randomly selected, and the fittest one of
	   them	is returned. The following method is defined:

	   tournament(?N?)
	       N defaults to 2.	Note that only one individual is returned per
	       call to this method.

       Random
	   Here, N individuals are randomly selected and returned.  The
	   following method is defined:

	   random(?N?)
	       N defaults to 1.

       Fittest
	   Here, the fittest N individuals of the whole	population are
	   returned.  The following method is defined:

	   topN(?N?)
	       N defaults to 1.
