Member Function Documentation

void IG::Num::IPenaltyEvaluator::SetPenaltyFunction	(	int	which,
		IRealFunctionPenalty	function
	)

Sets the penalty function used for evaluation of the specified penalty term.

Parameters:

which	Specifies which conatraint the penalty function applies to (zero based). In order to use one penalty function for all constraints, just set the penalty function with index 0.
function	Function to be used for evaluation of the specified penalty term.

Implemented in IG::Num::PenaltyEvaluator.

void IG::Num::IPenaltyEvaluator::SetPenaltyFunction	(	int	which,
		double	barrierLength,
		double	barrierHeight
	)

Sets the penalty function used for evaluation of the specified penalty term.

Parameters:

which	Specifies which conatraint the penalty function applies to (zero based). In order to use one penalty function for all constraints, just set the penalty function with index 0.
barrierLength	Characteristic barrier length of the created function. This is the length at which function grows from approximately 0 to characteristic height.
barrierHeight	Characteristic barrier height of the created function.

Implemented in IG::Num::PenaltyEvaluator.

void IG::Num::IPenaltyEvaluator::SetPenaltyFunction	(	int	which,
		double	barrierLength,
		double	barrierHeight,
		double	zeroEnd
	)

Sets the penalty function used for evaluation of the specified penalty term.

Parameters:

which	Specifies which conatraint the penalty function applies to (zero based). In order to use one penalty function for all constraints, just set the penalty function with index 0.
barrierLength	Characteristic barrier length of the created function. This is the length at which function grows from approximately 0 to characteristic height.
barrierHeight	Characteristic barrier height of the created function.
zeroEnd	Maximal argumet for which penalty function is still 0.

Implemented in IG::Num::PenaltyEvaluator.

bool IG::Num::IPenaltyEvaluator::CanSetBarrierLength ( int which )
