First of, it should be suffcient for the solvers, and minimizers with one interface to usersupplied functions and derivatives: f(R^1) -> R^1 f(R^1) -> R^m f(R^n) -> R^1 f(R^n) -> R^m Which can all be handled by an interface as: gsl_(???)_function_f: int (* f) (const gsl_vector * X, void * PARAMS, gsl_vector* F) gsl_(???)_function_df: int (* df) (const gsl_vector * X, void * PARAMS, gsl_matrix * J) gsl_(???)_function_fdf: int (* fdf) (const gsl_vector * X, void * PARAMS, gsl_vector * F,gsl_matrix * J) Currently each optimizing-pakage has it own similar definition, when the interface above clearly should be sufficient. ------- Next up, using the above definition GSL should be able to provide the users with a simplified interface to both solvers, minimizers and maximizers. I.e. use of the interface should only be 3-4 steps: 1. Initialise (alloc) pakage, using usersupplied values or default. 2. Do optimization. (3.) User-controlled iteration. 4. Terminate (free) pakage. Most of the pakage would ofcourse just be a wrapper for the existing solvers in GSL. My point is that little enhancements, and the ability to try functions implemented in gsl, without the need of a big program to setup *all* options, and allocations would greatly improve upon development-time, allthough the pakage might give a performancehit. It can be seen as a higherlevel interface to lowerlevel functions. If users want more direct control, they can offcourse use the lower-level pakages directly. Actually something as simple as a usefull numberingscheme for the number of independent variables in a function and number of returned values would be of great use (n,p are currently used inconsistently): nx = dimension of x - now n, p, m. nf = dimension of function returnvalue, now normally p. What the pakage should be called I don't know - gsl_optim might be a little too close to Matlab ;o) I wouldn't mind doing the framework, when I've finished the "direct search, SIMPLEX", currently underway. ^ permalink raw reply [flat|nested] 5+ messages in thread

The library is oriented towards interfacing to scripting languages, so the routines are low-level and broken down into fundamental components. The structs for gsl_multifit_.., gsl_multiroots_.., etc should be regarded as part of the interface, as a way to pass in a collection of arguments, rather than a mathematical object. The functions correspond to a library, rather than an 'environment'. So from this point of view its natural that the multiroots, multifit and multimin modules use different structs. If you'd like to make a separate higher-level interface for C/C++ programming feel free to do that. ^ permalink raw reply [flat|nested] 5+ messages in thread
