Hi Steven, this sounds like the library I was looking for. Would you mind reading my post [SciPy-User] Global Curve Fitting of 2 functions to 2 sets of data-curves http://mail.scipy.org/pipermail/scipy-user/2010-June/025674.html ? I got many interesting answers, where apparently the agreement wa

2010-06-16 Thread Steven G. Johnson
The NLopt library, available from http://ab-initio.mit.edu/nlopt provides a common interface for a large number of algorithms for both global and local nonlinear optimizations, both with and without gradient information, and including both bound constraints and nonlinear equality/inequali
