GeneticRange()

TMVA::GeneticRange::GeneticRange	(	TRandom3 *	rnd,
		Interval *	interval
	)

Random()

Double_t TMVA::GeneticRange::Random	(	Bool_t	near = kFALSE,
		Double_t	value = 0,
		Double_t	spread = 0.1,
		Bool_t	mirror = kFALSE
	)

creates a new random value for the coefficient Parameters:

• Bool_t near : takes a random value near the current value
• double value : this is the current value
• double spread : the sigma of the gaussian which is taken to calculate the new value
• Bool_t mirror : if the new value would be outside of the range, mirror = false maps the value between the constraints by periodic boundary conditions. With mirror = true, the value gets "reflected" on the boundaries.
