10 Jul 2014 ===================== Feasibility Benchmark ===================== H. Mittelmann (mittelmann@asu.edu)

Logfiles for these runs are at: plato.asu.edu/ftp/feas_bench_logs/

MILP problems mostly from MIPLIB2010 were solved for a feasible point

The following codes were run on an Intel i7-2600 with 4 threads:
CPLEX-12.6.0: CPLEX
FEASPUMP2: as implemented for interactive use at NEOS (utilizes CPLEX)
GUROBI-5.6.0: GUROBI
XPRESS-7.7.0: XPRESS
CBC-2.8.10: CBC
SYMPHONY-5.5.6: SYMPHONY

Times given are elapsed times in seconds. A time limit of 1 hr was imposed.
Shifted geometric means of the times are listed. For objective values see logfiles.
