The benchmark instances (v1) of MIPLIB2017 have been run by a number of codes.
The following codes were run with a limit of 2 hours on an AMD Ryzen 9 5900X (12 cores, 128GB)

COPT-8.0.3: COPT
SCIP/spx-10.0.0: SCIP
SCIPCO/spx-11.0.0: (SCIP-conc, parallel SCIP, forthcoming)
HiGHS-1.15.0 HiGHS
HiGHS-1.15.1 HiGHSp(parallel)
Optverse-2.0.1 OPTV
XSMOO Smoothie[FiberSCIP-cpx+HiGHS]

The instances were preprocessed by using SCIP to randomly perturb rows/columns and performing a quick presolve.

Unscaled and scaled shifted geometric means of run times

All non-successes are counted as max-time.
The third line lists the number of problems (240 total) solved.
MATLAB has HiGHS as default solver starting with 2024a.
