CP-SynC-XL - Python: leaderboard

Metric: Correct instances (%; share of the 4,577 CP-SynC-XL instances of 100 CSPLib and PyCSP3 combinatorial problems whose returned solution passes the reference verifier (feasibility, COP optimality) within 256 s; native algorithmic search: the LLM writes a Python solver, baseline prompt; final artefact after smoke and scaling-check refinement; greedy decoding). Source: arxiv.org. Saturation forecast: Around April 2027. 3 models tracked.
