Dear Octave developers,
I just wanted to let you know that I have put together a
free/open-source nonlinear-optimization package called NLopt, which is
callable from C and Fortran and also has Matlab (mex) and Octave (oct)
interfaces. NLopt can be downloaded from:
http://ab-initio.mit.edu/nlopt
It brings together a large number of different optimization algorithms
under a single interface, so that you can switch algorithms just by
changing one parameter. It supports local and global optimization;
unconstrained, bound-constrained, and nonlinearly constrained
optimization; and optimization using function values only or taking
advantage of function gradients if they are provided. It wraps around a
number of free/open-source packages written by various authors, and also
original implementations of several methods.
I'm not sure if there is a good place for you to link to external Octave
plugins, but if you wanted to link to NLopt somewhere that would be
great. (If you wanted to use NLopt more directly in Octave I would be
happy to help with that as well.)
Regards,
Steven G. Johnson
