      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. See http://ab-initio.mit.edu/wiki/index.php/NLopt
      _Introduction for more information on the available algorithms.
      During installation on Unix the NLopt code is downloaded and
      compiled from the NLopt website."""
