UOJ-Bench - Repair (Easy): leaderboard
Code repair on overt errors in UOJ-Bench (2026): minimally patch a partial-score submission so that it passes every test. UOJ-Bench (2026) draws on real Universal Online Judge submissions and community hacks and judges every answer on the judge itself; Pass@1 in percent, higher is better.
Metric: Pass@1 (%) on the 500 easy repair instances (partial-score submissions): the patched code, changing at most 10 percent of the original, must pass every test, single-turn zero-shot Pass@1 judged by the Universal Online Judge through its internal API (problem statements translated from Chinese to English; maximum response length at least 64k tokens); higher is better.
