From the release notes, in v9r1p1, gtlike has the DRMNFB and NEWMINUIT optimizers available. DRMNFB may converge better than DRMNGB and NEWMINUIT is a C++ translation (by Pat) of the MINUIT minimizer - and should be the same as MINUIT but fasteruses many of the same subroutines as DRMNGB but handles the derivative information differently and seems not to suffer from some of the convergence problems that Jean encountered with DRMNGB and binned analyses in the Catalog work. NEWMINUIT is an interface to the C++ version of MINUIT that is supported by CERN and shipped with ROOT. Both the DRMNFB and NEWMINUIT interfaces were implemented by Pat.
