Text2Opt-Bench - Multi-Objective Transportation: leaderboard

Bi-objective transportation MILPs trading cost against emissions, with fixed charges, minimum order quantities and supplier limits, from Text2Opt-Bench (Gao, Ge, Berenbeim, Bastian and Sala, 2026): the model reads the problem and its instance data in natural language and writes Gurobi code, and an answer counts when the solved objective matches the verified optimum. Pass@1 accuracy in percent on 50 problems; higher is better.

Metric: Pass@1 accuracy (%; bi-objective cost and emissions transportation MILP with fixed charges, 50 instances; solver-verified optimal objective). Source: arxiv.org. Saturation forecast: Estimated already saturated. 9 models tracked.
