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. It is used as an optional dependency in the Lilliput project by the I3GulliverNLoptFactory service as a minimization plugin for the Gulliver suite.
Linux distribution such as debian do include an NLopt package, unfortunately they do not include the c++ interface. So it may be necessary to install from source.
Apple Mac OS¶
On Mac OS, homebrew can be used:
$ brew tap homebrew/science
$ brew install homebrew/science/nlopt
If you are interested in using NLopt’s python interface independently of IceTray you can add the --with-python flag.
Install from Source¶
IceCube uses the c++ interface to NLopt and requires shared libraries, both of which must be turned on by command line options during configure.
$ wget https://github.com/stevengj/nlopt/archive/v2.7.1.tar.gz
$ tar xzvf nlopt-2.7.1.tar.gz
$ cd nlopt-2.7.1.tar.gz
$ ./configure --with-cxx --enable-shared
$ make
$ sudo make install
