Beyond the Frontier: Stochastic Backtracking for Efficient Test-Time Scaling 事件

Beyond the Frontier: Stochastic Backtracking for Efficient Test-Time Scaling arXiv:2605.25143v1 Announce Type: new Abstract: Test-time scaling improves language model reasoning by spending additional compute to explore multiple solution trajectories. The key challenge is to maximize accuracy while minimizing the total number of generated tokens during reasoning. Recent PRM-guided methods score intermediate prefixes to steer this search, but most are frontier-only: they keep only the current act
