Re: is TMinuit still a FORTRAN implementation?

Hi William,

   TMinuit is a C++ version of minuit (no Fortran involved). However, 
currently there is still some global state which prevents multiple 
instances of TMinuit. We are planning a complete overhaul of TMinuit 
to make it behave like a proper C++ class. Scheduled for early next
year.

Cheers, Fons.
