Hi Luis! Glad to hear Minuit is still in use. If it were removed from main PDL, it would only be to make it available separately on CPAN as PDL::Minuit (somewhat similar to PDL::FFTW3).
I’m afraid I’m not very knowledgeable about mathematical optimisation, but I am aware of other options for PDL somewhat in that sphere: * https://metacpan.org/pod/PDL::Opt::NonLinear * https://metacpan.org/pod/PDL::Opt::QP * https://metacpan.org/pod/PDL::Opt::Simplex (in main PDL) * https://metacpan.org/pod/PDL::Fit::LM (in main PDL) * https://metacpan.org/pod/PDL::Fit::Levmar Also, once the OpenCV stuff is cracked, that will be an example of a PDL library using C++, which would then hopefully make a Minuit 2 interface much easier. While I think of it, any chance to look at https://github.com/wlmb/Photonic/pull/23? :-) Best regards, Ed From: Luis Mochan<mailto:moc...@icf.unam.mx> Sent: 11 April 2022 20:41 To: pdl-general@lists.sourceforge.net<mailto:pdl-general@lists.sourceforge.net> Subject: Re: [Pdl-general] PDL 2.078 On Mon, Apr 11, 2022 at 04:12:43PM +0000, Ed . wrote: > ... > ...The Fortran code in those submodules (Minuit and Slatec) are > written in Fortran 77, and are dramatically obsolete.

I do... :( What would be the recommended modules, alternative to minuit, to optimize multiparameter functions using the current PDL? Regards, Luis -- o W.
