9 Dec 2011 ========================================= Infeasibility Detection for MILP Problems ========================================= H. Mittelmann (mittelmann@asu.edu)

The following codes were run on the infeasible problems from MIPLIB2010 with the MIPLIB2010 scripts on an Intel Xeon X5680 (32GB, Linux, 64 bits, 2*6 cores).

CPLEX-12.4.0.0: CPLEX
GUROBI-4.6.1: GUROBI
ug[SCIP/spx/cpx]: Parallel development version of SCIP
CBC-2.7.4: CBC
XPRESS-7.2.1: XPRESS

Table for 12 threads, Result files per solver, Log files per solver

Statistics of the problems can be obtained from the MIPLIB2010 webpage.

Geometric means of times

All non-successes are counted as max-time. The fastest solver is scaled to 1.
