NLCO - Set-L - Accuracy: leaderboard

Share of large (Set-L) NLCO instances, 50 per task, where the model's own discrete answer is feasible and reaches the solver's optimal objective within tolerance; no code or external solver is allowed. Percent, higher is better. NLCO (Jiang et al., Eindhoven University of Technology and others, 2026) renders 43 combinatorial optimization problem types (routing, packing, scheduling, covering, assignment) as natural-language scenarios with solver-annotated reference solutions.

Metric: Accuracy: feasible and matching the solver-optimal objective (%). Source: arxiv.org. Saturation forecast: Around February 2027. 16 models tracked.
