Hello,
I am trying to run Minuit with 30 free parameters, however only 15 parameters are changed in the process (the others stay with the initial value, error = 1.41421e+00 and step -0.00000e+00).
I have already seen this post More than 25 parameters in Minuit, but it didn’t work for me. My code is based in the example (using TMinuit class): root.cern.ch/root/html534/tutori … fit.C.html.
I have obtained results with Minuit without problems when the fit has less than 15 parameters.
Is this a limitation of Minuit? If it is not, how can I properly use Minuit with more than 15 parameters?
Thanks in advance for the answers.
Best regards,
Paulo
