9 Jan 2012 ======================================================= 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-12.4.0.0: CPLEX
GUROBI-4.6.1: GUROBI
ug[SCIP/cpx/spx]: Parallel development version of SCIP (SCIP+CPLEX/CLP/SOPLEX on 1 thread)
CBC-2.7.4: CBC
XPRESS-7.2.1: XPRESS
GLPK-4.47: 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 iMIPLIB2010 webpage.

Geometric means of times
All non-successes are counted as max-time. The fastest solver is scaled to 1. The second line lists the number of problems (87 total) solved. threads CBC CPLEX GLPK GUROBI LPSOLVE SCIPC SCIPL SCIPS XPRESS ------------------------------------------------------------------------------- 1 10.2 1.45 22.11 1 19.4 3.76 6.4 5.33 1.29 solved 41 73 3 77 5 63 52 57 74 -------------------------------------------------------------------------------- threads CBC CPLEX FSCIPC FSCIPS GUROBI XPRESS ------------------------------------------------------------------- 4 10.29 1 5.80 9.44 1 1.26 solved 52 84 66 64 85 79 ------------------------------------------------------------------- threads CBC CPLEX FSCIPC FSCIPS GUROBI XPRESS ------------------------------------------------------------------- 12 12.2 1.1 8.64 13.3 1 1.36 solved 56 84 70 63 87 83 -------------------------------------------------------------------
