How to use DBS, BCSE and other variance reduction techniques in egs++?

[CQUswl]

I'd like to make full use of the variance reduction techniques in the egs++ code, but I haven't found instructions on how to use DBS, BCSE, etc.

I don't know if these variance reduction tricks from BEAMnrc are available in egs++.

The egs_chamber application has a variety of VRTs built in, I would start there. Uniform brems splitting can be done using:

We are currently working on DBS (#974) but it's not ready for use yet.

Thank you very much for your help. I see in egs_radiative_splitting.h that in addition to URS, there are DRS and DRSf, is there any difference between these three?

[rtownson]

The references to DRS and DRSf are just placeholders, they are not used anywhere yet.

Note that radiative splitting recently had a bug fix: #1011

If the radiative splitting is needed, you may want to checkout that PR to get the changes.
