| - | '''NLopt''' is a free/open-source nonlinear optimization library that we have been using internally, and plan to release by the end of 2008. It provides a common interface for a number of different optimization algorithms, both by other authors (where available as free software) and original implementations by us, and is designed to make it easy to switch between different algorithms to see which ones work best for your problem. It includes both local and global optimization algorithms, for functions either with or without derivatives supplied, and supports unconstrained, box-constrained, and nonlinear-inequality constrained problems. | + | [[Image:Nlopt-logo.png|center|800px]] |

NLopt
NLopt is a free/open-source library for nonlinear optimization, providing a common interface for a number of different free optimization routines available online as well as original implementations of various other algorithms. Its features include:
- Callable from C, C++, Fortran, w:GNU Octave, and Matlab.
- A common interface for many different algorithms—try a different algorithm just by changing one parameter.
- Both global and local optimization algorithms.
- Both derivative-free and gradient-based optimization algorithms.
- Algorithms for unconstrained optimization, bound-constrained optimization, and general nonlinear inequality constraints.
- Free/open-source software under the GNU LGPL (and looser licenses for some portions of NLopt).
Download and installation
Version 1.0 of NLopt is currently available from our web site:
See the NLopt release notes for the release history. NLopt is designed to be installed on any Unix-like system (GNU/Linux is fine) with a C compiler, using the standard
./configure && make && su -c 'make install'
procedure. See the NLopt installation instructions for more information.
