Could I set a few groups of parameters combination in one code script?

Hi，all
I come across a practical problems，that when I would like to try different paramter values in BDT algorithm（such as setting the maxdepth between 5~20）I have to run the code many times when I change the maxdepth value one by one.I wonder there is a directly way to set a few groups of parameters combination in one code script.And after once running I could obtain all the results conviniently.Thanks so much!!

Hi,

There is something foreseen in MethodBDT in the function MethodBDT::OptimizeTuningParameters, see (ROOT: TMVA::MethodBDT Class Reference)
The function can be used also with the class HyperParameterOptimization (ROOT: TMVA::HyperParameterOptimisation Class Reference)

This is not well documented and still experimental .The parameters that are changed and their ranges are hard-coded in the implementation of MethodBDT::OptimizeTuningParameters.
