The codes

  IPOPT-3.6.1    http://projects.coin-or.org/Ipopt (using MA27)
  KNITRO-6.0     http://www.ziena.com/knitro.html
  LOQO-6.07      http://www.princeton.edu/~rvdb/
  PENNON-0.9     http://www.penopt.de/pennlp.html
  SNOPT-7.2-1    http://www.scicomp.ucsd.edu/~peg/
  CONOPT-3.14    http://www.conopt.com/
are used to solve some larger NLP instances coded in AMPL format. The sources of the AMPL scripts are (partly with increased dimensions):

  [2]   http://www.sor.princeton.edu/~rvdb/ampl/nlmodels/cute/
