Dear experts

I wonder what is the number of MaxFunctionCalls() in ROOT::Math::Minimizer and should I set it manually?

std::cout << MaxFunctionCalls() << std::endl;

This will return 0 and in the source code it says “Remain default” but I don’t know what number is the “default”

Thank you for pointing to some experts! And in addition I wonder what is the default value of ROOT::Math::Minimizer::Precision(), maybe some experts can point me to some page that explains every default value.

Any suggestions…?

Did you try with:

MinimizerOptions::Print(cout) ?
