ROOT::Minuit2::MnSimplex Class Reference

API class for minimization using the Simplex method, which does not need and use the derivatives of the function, but only function values.

More information on the minimization method is available here.

It allows for user interaction: set/change parameters, do minimization, change parameters, re-do minimization etc.;
