Hi,

Thanks for the messsage.  I'm not aware of anyone else working on
constrained optimisation so you're welcome to work on that.  We can
sort out any documentation problems.

An important step is to see if there is an interface which can support
a large class of algorithms as in the multifit/ and multmin/
directories.  I wrote some notes in the document doc/gsl-design.texi
which might be helpful there.

best regards,
