I am working on incorporating variance reduction into a Geant4 program. More specifically, I would like to assign a weight to a particle at the very beginning (and adjusting the weight depending on the initial direction).
What is the difference between
G4PrimaryVertex* vert; vert->SetWeight(w1);
G4PrimaryParticle* part; part->SetWeight(w2);
And more specifically:
- Are both weights independent? Or does this result in a weight of w=w1*w2?
- Is the weight "transported", i.e. is it being accounted for during calculation of deposited energy?
BTW: A very similar question was already asked http://hypernews.slac.stanford.edu:5090/HyperNews/geant4/get/particles/93.html in 2004 but nobody replied.
