TMinuit with constraint

ROOT
1

Hi ROOTer,

I am trying to minimize my FCN using the TMinuit with parameters x1, x2, and x3. The x1, x2, and x3 themselves have no constraints, but x1 + x2 + x3 > 0.

My question is: How to impose this constraint during the minimization? Should I manually set the FCN to infinity when x1 + x2 + x3 < 0 is satisfied?

With the best respect,
Boan
