Constructor & Destructor Documentation

◆ GeneticRange()

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

defines the "f" (from) and "t" (to) of the coefficient and takes a randomgenerator

◆ ~GeneticRange()

TMVA::GeneticRange::~GeneticRange ( )
virtual

destructor

◆ GetFrom()

◆ GetTotalLength()

◆ 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.
