void TMVA::PDEFoamDecisionTree::Explore ( PDEFoamCell * cell )

protectedvirtual

Internal subprogram used by Create.

It explores newly defined cell with according to the decision tree logic. The separation set via the 'sepType' option in the constructor.

The optimal division point for eventual future cell division is determined/recorded. Note that links to parents and initial volume = 1/2 parent has to be already defined prior to calling this routine.

Note, that according to the decision tree logic, a cell is only split, if the number of (unweighted) events in each dautghter cell is greater than fNmin.

Reimplemented from TMVA::PDEFoam.
