Models: all 125 MIPs from the GAMS LINLib

Solvers:

1. CPLEX 11.2.0 (as in GAMS 22.9)
2. CBC 2.2 (stable branch, rev. 1120)
   using Clp/stable/1.8 rev. 1320, CoinUtils/stable/2.3 rev. 1125, Cgl/stable/0.53 rev. 712, Osi/stable/0.99 rev. 1328
   with extra compiler flags: -DDISALLOW_PRINTING -DCLP_FAST_CODE -DCOIN_FAST_CODE -DCOIN_USE_RESTRICT -DNEW_STYLE_SOLVER=0 -march=native
3. SCIP 1.1.0 (incl. Clp interface bugfix)
   using Clp/stable/1.8 rev. 1320, CoinUtils/stable/2.3 rev. 1125
   with extra compiler flags: -DDISALLOW_PRINTING -DCLP_FAST_CODE -DCOIN_FAST_CODE -DCOIN_USE_RESTRICT -DNEW_STYLE_SOLVER=0 -march=native
   with ATLAS 3.8.2 as Blas substitute and Lapack 3.1.1

Timelimit: 3600 seconds
Gap tolerance: 0

Platform:

• Intel Core 2 Duo CPU T7500, 2.2 GHz, 2 GB RAM
• Linux 2.6.22.18, SuSE Linux 10.3, 32 Bit
• gcc 4.2.1

Results

Notes:

• SCIP 1.1: For the instances air04 and misc06 the solution status has been changed from "solved to optimality" to "integer feasible" and the objective estimate has been set to "NA" because other solvers found a better solution than the reported one.
