# Unit Commitment on PGLib-UC Against HiGHS

Certified Objectives on 22 Power-System Instances at 600 s.

11/5/6 vs HiGHS, 1 core

13/4/5 vs HiGHS, 16 cores

22 PGLib-UC instances, 600 s

0 uncertified objectives

- Relax-and-fix + fix-and-optimize on the official PGLib-UC model; every objective certified by re-solving the official model with the commitment fixed
- vs HiGHS on the official MIP: 11/5/6 at 1 core, 13/4/5 at 16 cores
- California 2014 cases: HiGHS finds no solution in 600 s; ours certifies 48,233 (bound 48,226)
- FERC instances: neither solver finds a solution (tie)
