This dataset is about contest-level math problems formalized in Lean 4.
Our dataset contains 57231 problems in the split of Lean Workbook and 82893 problems in the split of Lean Workbook Plus. We provide the natural language statement, answer, formal statement, and formal proof (if available) for each problem. These data can support autoformalization model training and searching for proofs.
We open-source our code and our data.
Our test environment is based on Lean… See the full description on the dataset page:
