I am trying to understand some Minuit2 output. If I do the following:
ROOT::Math::MinimizerOptions::SetDefaultTolerance(0.01); ROOT::Math::MinimizerOptions::SetDefaultMinimizer("Minuit2"); ROOT::Math::MinimizerOptions::SetDefaultPrintLevel(2);
and then start minimization, I get approximately the following:
It correctly reports in the beginning that the requested tolerance is 0.01 but then for some reason says “start iterating until Edm is < 2e-05”
Could you please let me know which of the two tolerances is actually used during minimization? My impression (judging by the subsequent output) is that Minuit2 does not respect the change of the default tolerance value. If so, how could I set the minimization tolerance for Minuit2?
