Re: [ROOT] minimization class within ROOT

Hi Sebastien,

Currently, we have only two classes of minimizers (The Minuit family
and TFumili).
We are currently working on a linear fitter that could be used
to fit distributions with a combination of linear functions.
Instead of a conventional minimisation, this implies only a matrix
inversion.
A RobustFitter algorithm is also in the pipeline.

Could you indicate the rationale behind your question?
