WebThe best package I'm aware of for general nonlinear optimization is IPOPT[1]. Apparently Matthew Xu maintains a set of Python bindings to IPOPT, so this might be somewhere to start. UPDATE: the current maintained Python bindings for IPOPT seems to be ipyopt [1]: Andreas Wachter is a personal friend, so I may be a bit biased.

WebAs a convenient feature, Ipopt provides the option to run a simple derivative checker, based on finite differences, before the optimization is started. To use the derivative checker, you need to use the option derivative_test.
