10 * Description: *
11 * Class PDEFoamDecisionTreeDensity is a class representing *
12 * n-dimensional real positive integrand function *
13 * The main function is Density() which provides the event density at a *
14 * given point during the foam build-up (sampling). *

This is a concrete implementation of PDEFoam.
virtual Double_t Density(std::vector< Double_t > &Xarg, Double_t &event_density)
This function is not used in the decision tree like PDEFoam, instead FillHist() is used.
virtual void FillHistograms(TMVA::Volume &, std::vector< TH1D * > &, std::vector< TH1D * > &, std::vector< TH1D * > &, std::vector< TH1D * > &)
Fill the given histograms with signal and background events, which are found in the volume.
This is an abstract class, which provides an interface for a PDEFoam density estimator.
Volume for BinarySearchTree.
