This directory contains subdirectories with AMPL files for various optimization problems. At present there are: ================================================================== ellip_ampl: pde-constrained nlp's from boundary and distributed control of elliptic pde's ------------------------------------------------------------------ globallib_ampl: GAMS Performance World lib converted to scalar AMPL ------------------------------------------------------------------ lukvl_ampl: linearly constrained NLP's, also in CUTE ------------------------------------------------------------------ milp_ampl: mixed integer LP's collected and converted by us ------------------------------------------------------------------ miplib2003_ampl: The MIPLIB2003 collection of mixed integer LP's ------------------------------------------------------------------ miplib3_ampl: Old MIPLIB3 ------------------------------------------------------------------ miqp_ampl: mixed-integer quadratic problems ------------------------------------------------------------------ nda_ampl: minimax and other nonsmooth problems ------------------------------------------------------------------ netlib_ampl: the NETLIB LP collection ------------------------------------------------------------------ nlp_ampl: general NLP problems converted from Fortran ------------------------------------------------------------------ nlp_bound_ampl: NLPs with only bound constraints from CUTEr ------------------------------------------------------------------ nonsys_ampl: nonlinear systems of equations ------------------------------------------------------------------ parabol_ampl: parabolic boundary control problems ------------------------------------------------------------------ qcqp_ampl: quadratically constrained QP's from the 7th DIMACS challenge ------------------------------------------------------------------ rqcqp_ampl: randomly generated quadratically constrained QP's ------------------------------------------------------------------ qpdata_ampl: convex QP's (the QPDATA collection) ------------------------------------------------------------------ sqp_ampl: randomly generated convex QP's ------------------------------------------------------------------ sysid_ampl: NLPs from our research in systems identification ================================================================== More files will be added Hans Mittelmann (mittelmann@asu.edu) 10/2005
