Is > there any suggestion ? 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, Brian Gough
