Logfiles for these runs are at: plato.asu.edu/ftp/feas_bench_logs/
MILP problems from MIPLIB2010 were solved for a feasible point
The following codes were run on an Intel i7-2600
(3.4 GHz, 16GB, Linux, 4 cores) with 4 threads:
CPLEX-12.4.0.0: CPLEX
FEASPUMP2:
as implemented for interactive use at NEOS (utilizes CPLEX)
GUROBI-4.6.1: GUROBI
XPRESS-7.2.1: XPRESS
CBC-2.7.5: CBC
Times given are elapsed times in seconds. A time limit of 1 hr was imposed.
Geometric means of the times are listed. For objective values see logfiles.
