Detailed Description

This class is interface for selection operation which selects chromosomes from population which are going to be used as parents in production of new chromosomes.

This class has no built-in synchronizator, so LOCK_OBJECT and LOCK_THIS_OBJECT macros cannot be used with instances of this class. No public or private methods are thread-safe.

virtual void GACALL Population::GaSelectionOperation::operator()	(	const GaPopulation &	population,
		const GaSelectionParams &	parameters,
		GaSelectionResultSet &	result
	)			const [pure virtual]

operator () performs replacement operation.

Parameters:

	population	reference to population from which chromosomes are selected.
	parameters	reference to parameters of selection operation.
	result	pointer to result set which is used to store selected chromosomes.

Implemented in Population::SelectionOperations::GaSelectBest, Population::SelectionOperations::GaSelectRandom, Population::SelectionOperations::GaSelectRandomBest, Population::SelectionOperations::GaSelectRouletteWheel, Population::SelectionOperations::GaSelectTournament, and Population::SelectionOperations::GaSelectWorst.

virtual GaSelectionResultSet* GACALL Population::GaSelectionOperation::MakeResultSet	(	GaPopulation *	population,
		const GaSelectionParams &	parameters
	)			const [inline, virtual]

MakeResultSet method makes result set used by selection operation for storing chromosomes indices. Caller is responsible for memory allocated by this method for result set object.

This method is thread-safe.

Parameters:

	population	pointer to population to which result set is bound.
	parameters	reference to parameters of selection operation.

Returns:

Method returns pointer to newly created result set.
