Minuit implementation in IGOR (or minuit-based XOP)

Share icon

I would greatly love if CERN's chi-square minimization routines (Minuit package) could be used in conjunction with IGOR fitting functions. I tested them and in almost all cases they revealed to be faster and more efficient than Levenberg-Marquardt. Minuit is also available in C. If somebody could write an XOP (as the one implementing genetic optmisation) to use Minuit inside IGOR, it would be fantastic.

I think that C-Minuit is licensed under the GPL which means that it couldn't be linked with the XOP toolkit _and_ distributed. However, one could make such an XOP and only distribute the source code, leaving it up to the end user to build it.

Yeah, that is what I meant. I know that Minuit has already been used as a minimization tool for data analysis software (non IGOR-based) at ESRF (light source in France), so I think it is feasible...
