I am a mechanical engineer, retired now, and use OpenOffice under Debian Lenny. Sometimes I use an optimizationprogram I have used all my live when in business, to find solutions in my technical work. It could handle all the non-linear problems I have encountered. The program is pretty old, about 30 years. It is free software now, written in Fortran, although I had it translated to Turbo Pascal. The TurboPascal version I still use. The program (MINI) is rather small, about 800 lines of code. It can handle constrains, can handle any amount of variables and is fast (nowadays!). I have both the the sources of course. You may have it, but I can not give much assistance, I am not a programmer. I can explain how it works, give examples and so on. I live in the Netherlands, perhaps there is someone in our country who can do the job of putting it into Calc.
I'm not in the Netherlands, but I'm very interested in that code. We do have an API in Calc for solver extensions, and a colleague is just now working on a different implementation, so we could also try to adapt your code to that API. Are you willing to submit it under the Contributor Agreement (see bottom of http://contributing.openoffice.org/programming.html)?
