ComBench - Construction Pass Rate: leaderboard
ComBench evaluates rigorous proof reasoning and constructive realization on 100 Olympiad-level combinatorics problems (50 analysis-centric, 50 construction-centric). This board reports Per-sample construction pass rate (%): the share of construction-centric solutions whose witness is accepted by the deterministic verifier; higher is better.
Metric: Per-sample construction pass rate (%): the share of construction-centric solutions whose witness is accepted by the deterministic verifier; higher is better. Source: arxiv.org. Saturation forecast: Around February 2027. 10 models tracked.
