 You will notice that the dataset contains various splits (which are not exactly splits, but rather different versions of the dataset):
-- `v1`: The original dataset, which contains all problems initially designed, including those with known issues. More details about the issues can be found in the [changelog](cp_bench_changes.md).
-- `v1_verified`: A stripped-down version of the original dataset (v1) that has been verified to contain complete problem specifications with matching ground-truth models. This version is recommended for use in evaluations.
