Constructor & Destructor Documentation

template<class MOEOT>

moeoFrontByFrontSharingDiversityAssignment< MOEOT >::moeoFrontByFrontSharingDiversityAssignment	(	moeoDistance< MOEOT, double > &	_distance,
		double	_nicheSize = 0.5,
		double	_alpha = 2.0
	)			[inline]

Ctor.

Parameters:

	_distance	the distance used to compute the neighborhood of solutions (can be related to the decision space or the objective space)
	_nicheSize	neighborhood size in terms of radius distance (closely related to the way the distances are computed)
	_alpha	parameter used to regulate the shape of the sharing function

template<class MOEOT>

moeoFrontByFrontSharingDiversityAssignment< MOEOT >::moeoFrontByFrontSharingDiversityAssignment	(	double	_nicheSize = 0.5,
		double	_alpha = 2.0
	)			[inline]

Ctor with an euclidean distance (with normalized objective values) in the objective space is used as default.

Parameters:

	_nicheSize	neighborhood size in terms of radius distance (closely related to the way the distances are computed)
	_alpha	parameter used to regulate the shape of the sharing function

Member Function Documentation

template<class MOEOT>

void moeoFrontByFrontSharingDiversityAssignment< MOEOT >::updateByDeleting	(	eoPop< MOEOT > &	_pop,
		ObjectiveVector &	_objVec
	)			[inline, virtual]

Warning:

NOT IMPLEMENTED, DO NOTHING ! Updates the diversity values of the whole population _pop by taking the deletion of the objective vector _objVec into account.

Parameters:

	_pop	the population
	_objVec	the objective vector

Warning:

NOT IMPLEMENTED, DO NOTHING !

Reimplemented from moeoSharingDiversityAssignment< MOEOT >.
