Text2Opt-Bench - Stochastic Transportation: leaderboard

Two-stage stochastic transportation MILPs with sample-average approximation and chance constraints, 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 (%; two-stage stochastic MILP with sample-average approximation and chance constraints, 50 instances; solver-verified optimal objective). Source: arxiv.org. Saturation forecast: Around February 2027. 9 models tracked.
