Benchmarking Against Competitive Programming Standards

Reinforcement Learning and Test Time Compute: Path to AGI

Impact of Increased Compute on Model Performance

• Increasing both reinforcement learning compute and test time inference compute consistently improves model performance, allowing for longer thinking times and more tokens during inference.

• The scaling of training time compute leads to improved performance, with specialized test time inference strategies engineered for competitive programming being human-written.

Clustering and Reranking Strategies

• The process involves dividing each problem into subtasks, sampling solutions from the model, and employing clustering and reranking to select the best solution.

• Clustering groups similar outputs together, while reranking scores each solution based on quality errors in generated test inputs against public test cases.

Performance Metrics

• The system submitted up to 50 solutions in a round-robin fashion over subtasks, starting from the hardest problems. This approach led to significant success.

• Model 01 II achieved a codeforces rating of 1807, outperforming 93% of competitors; with added handwritten strategies, it reached the 998th percentile at a score of 2214.

Comparison Between Models

• Model 03 outperformed Model 01 II significantly by achieving a codeforces rating of 2724 without relying on complex human-defined strategies.

• While Model 01 II's success depended on intricate human intervention for strategy implementation, Model 03 demonstrated that simply scaling up reinforcement learning could yield better results.

Conclusion: Scaling AI for Future Success

• Just scaling up reinforcement learning and test time compute can lead to superior performance without needing manual partitioning or submission strategies.
