Codeforces Competitive Programming Problems and Solutions

Codeforces, a popular competitive programming platform, provides a collection of over 10,000 unique algorithmic problems. The dataset, created by open-r1, includes problems from the earliest contests up to 2025, designed to test code reasoning capabilities.

Use Cases

• Train large language models on problem statements and solution code for code generation tasks.
• Analyze solution patterns and algorithmic tags to classify problem difficulty or type.
• Benchmark model performance on unseen contest problems using problem IDs and associated metadata.
• Study the evolution of problem complexity and topics over time using contest timestamps.

Strengths

• Over 10,000 unique problems providing broad coverage of algorithmic concepts.
• Temporal coverage spans from the platform's inception to 2025, enabling longitudinal analysis.

Limitations

• Specific column names, data schema, and total row count are not detailed in the provided description.
• Potential class imbalance if certain problem types or difficulty levels are over-represented.
