BEST Dataset

This repository hosts the benchmark data for BEST: Benchmarking Efficiency in Space and Time for LLM-Generated Code.

Files

data.csv: C++ benchmark metadata.
data_py.csv: Python benchmark metadata.
test_cases/*.tar.zst: sharded test cases.
checksums.sha256: SHA-256 checksums for all files in this repository.

Layout

Place the files under the BEST repository's data/ directory:

data/data.csv
data/data_py.csv
data/test_cases/<problem_id>/<case_id>.in
data/test_cases/<problem_id>/<case_id>.out

The test case archives preserve test_cases/<problem_id>/... paths. Extract them under data/ to restore the expected layout.
