From OpenOpt
Hello!
Welcome to new OpenOpt home!
We focus on scientific/engineering software development using RAD abilities of Python language, accompanied with free scientific libraries such as NumPy and SciPy. Our mainstream research activity is numerical optimization, including nonsmooth optimization and solving systems of nonlinear equations.

You may be interested in our completely free (license: BSD) cross-platform (Linux, Windows, Mac etc) software, written using Python + NumPy:
- OpenOpt framework - universal numerical optimization package with several own solvers (eg ralg) and connections to lots of other, graphical output of convergence and lots of other goodies
- FuncDesigner - tool to rapidly build functions and get their derivatives via automatic differentiation. Also, you can solve systems of linear/nonlinear equations and numerical optimization problems coded in FuncDesigner by OpenOpt (see some examples in its doc)
- DerApproximator - tool to get (or check user-supplied) derivatives via finite-difference approximation
