Text2Opt-Bench - Resource-Constrained Project Scheduling: leaderboard
Multi-mode resource-constrained project scheduling MILPs with time lags, budget and deadlines, 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 (%; multi-mode project scheduling MILP with time lags, budget and deadlines, 50 instances; solver-verified optimal objective). Source: arxiv.org. Saturation forecast: Estimated already saturated. 9 models tracked.
