[Gretl-devel] Feature requests regarding gretl 's minimization algorithms

I have some feature requests regarding gretl's minimization algorithms, which are useful for user-written functions: As I understand it from the User's guide, gretl uses several numerical optimization algorithms, e.g. the Frisch-Newton interior point solver and the Barrodale-Roberts simplex algorithm for quantile esitmation, the Levenberg-Marquardt algorithm for NLS estimation and the BFGS algorithm for MLE. Of these algorithms only the BFGS method is available for user-written functions. Would it be hard to also make the other methods available for user-writen functions, just as the BFGSmax method is avaialble? If not I hope they could be made available. Secondly, if it is not too much work, I would like to see the Nelder-Mead numerical optimization algorithm implemented in gretl and available for user-written functions. Andreas
