28 Mar 2014 ======================================================= Mixed Integer Linear Programming Benchmark (MIPLIB2010) ======================================================= H. Mittelmann (mittelmann@asu.edu)

The following codes were run on the MIPLIB2010 benchmark set with the MIPLIB2010 scripts on an Intel Xeon X5680 (32GB, Linux, 64 bits, 2*6 cores), with one, four, and twelve threads. (deterministically) and a time limit of 1 hour. These are updated and extended versions of the results produced for the MIPLIB2010 paper.

CPLEX-12.6.0: CPLEX
GUROBI-5.6.0 GUROBI
ug[SCIP/cpx/spx]-3.1.0: Parallel development version of SCIP (SCIP+CPLEX/CLP/SOPLEX on 1 thread)
CBC-2.8.7: CBC
XPRESS-7.7.0: XPRESS
GLPK-4.52: GLPK
LP_SOLVE-5.5.2: LP_SOLVE

Table for single thread, Result files per solver, Log files per solver

Table for 4 threads, Result files per solver, Log files per solver

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

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