Researchers have developed a new framework to improve the performance of Large Reasoning Models (LRMs) on complex mathematical tasks. This training-free approach leverages output disagreement as a signal to dynamically select the most appropriate test-time scaling strategy for each instance. The system routes consistent cases to lightweight resolution, moderate disagreements to majority voting, and highly ambiguous problems to rewriting-based reformulation. Experiments show this method enhances accuracy by 3-7% while reducing computational costs compared to existing techniques. AI
