MIPLIB-NL (Pass@8): leaderboard

Metric: Pass@8 accuracy (%): an instance counts as solved when any of 8 independent samples reaches the optimum (MIPLIB-NL: natural-language optimization-modeling problems reverse-generated one-to-one from MIPLIB 2017 mixed-integer programs (223 instances, the 8 infeasible and 15 open ones excluded from scoring), with model and data specified separately; the model writes the formulation and solver code, which are executed; an instance is solved when the solver objective matches the certified optimum within 1e-6 relative error; temperature 0.6; direct prompting, no tools); higher is better. Source: arxiv.org. Saturation forecast: Around July 2027. 14 models tracked.
