[ANN] NLopt, a nonlinear optimization library, now with Guile interface

[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/inequality constraints.

NLopt is written in C, but now includes a Guile interface (as well as 
interfaces for C++, Fortran, Matlab, Octave, and Python).

It is free software under the GNU LGPL.
