这是一个从`open-r1/codeforces`数据集中抽取的512个示例子集，主要用于Plan-CRL Codeforces反馈实验。数据集筛选条件包括：存在评分、完整的官方测试、仅限标准输入输出任务、无生成检查器、官方测试存在且最多16个官方测试用例。数据集按照ELO评分分为四个平衡组别，每组128个示例。有用的字段包括提示、参考解决方案、测试用例、元数据评分、ELO组别、标题和标签等。

A 512-example subset sampled from `open-r1/codeforces` (`verifiable`, `train`) for Plan-CRL Codeforces feedback experiments. The dataset is filtered based on criteria such as presence of rating, complete official tests, stdio-only tasks, no generated checker, official tests present, and at most 16 official test cases. It is balanced into four ELO groups with 128 examples each. Useful fields include prompt, reference_solution, tests, metadata.rating, metadata.elo_group, metadata.title, and metadata.tags.
