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

Definition at line 45 of file GeneticRange.cxx.

◆ ~GeneticRange()

TMVA::GeneticRange::~GeneticRange ( )
virtual

destructor

Definition at line 118 of file GeneticRange.cxx.

Member Function Documentation

◆ Class()

static TClass * TMVA::GeneticRange::Class ( )
static
Returns
TClass describing this class

◆ Class_Name()

static const char * TMVA::GeneticRange::Class_Name ( )
static
Returns
Name of this class

◆ Class_Version()

static constexpr Version_t TMVA::GeneticRange::Class_Version ( )
inlinestaticconstexpr
Returns
Version of this class

Returns
Name of the file containing the class declaration

◆ IsA()

virtual TClass * TMVA::GeneticRange::IsA ( ) const
inlinevirtual
Returns
TClass describing current object

Definition at line 73 of file GeneticRange.h.

◆ 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.
