Text2Opt-Bench - Vehicle Routing with Time Windows: leaderboard
Vehicle routing MILPs with time windows, vehicle capacity and subtour elimination, 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 (%; vehicle routing MILP with time windows, capacity and subtour elimination, 50 instances; solver-verified optimal objective). Source: arxiv.org. Saturation forecast: Around February 2027. 9 models tracked.
