NLopt is a library for nonlinear local and global optimization, for
functions with and without gradient information. It is designed as
a simple, unified interface and packaging of several free/open-source
nonlinear optimization libraries.

The latest release can be downloaded from the [NLopt releases](https://github.com/stevengj/nlopt/releases) page on Github, and the
[NLopt manual](https://nlopt.readthedocs.io/en/latest/) is hosted on readthedocs.

To build it refer to the [installation instructions](https://nlopt.readthedocs.io/en/latest/#download-and-installation).

To use in your C/C++ programs see the [C reference manual](https://nlopt.readthedocs.io/en/latest/NLopt_Reference/).

There are also interfaces for [C++](https://nlopt.readthedocs.io/en/latest/NLopt_C-plus-plus_Reference/), [Fortran](https://nlopt.readthedocs.io/en/latest/NLopt_Fortran_Reference/), [Python](https://nlopt.readthedocs.io/en/latest/NLopt_Python_Reference/), [Matlab or GNU Octave](https://nlopt.readthedocs.io/en/latest/NLopt_Matlab_Reference/), [OCaml](https://bitbucket.org/mkur/nlopt-ocaml),
