Logiles at plato.asu.edu/ftp/miqp_logs/

The MPS-datafiles are in plato.asu.edu/ftp/miqp/ and the AMPL files in plato.asu.edu/ftp/ampl_files/miqp_ampl/ and egon.cheme.cmu.edu/ibm/files/

The following codes were run in default mode on a 2.66GHz Intel Core2 Quad, For accuracy reached, see logfiles. In the last columns are results for the QCQPs obtained by rewriting the QPs as: min t, subject to quadratic obj <= t plus constraints. SCIP does this transformation itself. SCIP uses relgap=0;

CPLEX-12.4.0.0: CPLEX (QCQP with 12.3)
Bonmin-1.5.1: projects.coin-or.org/Bonmin (Bonmin: hybrid algorithm. with Cbc)
Couenne-0.4.1: projects.coin-or.org/Couenne
FilMINT: currently only at NEOS, (run locally)
GUROBI-4.6.1: gurobi.com
SCIP-2.1.0: scip.zib.de (with CPLEX and IPOPT)
XPRESS-7.2.1: XPRESS

Times given are user times in seconds. A time limit of 10,800 seconds was imposed. "t" time limit exceeded, "f" fail, "c" problem convex.
