Adaptive Test-Time Compute Allocation via Learned Heuristics for LLM Reasoning
This paper proposes a state-level selective verification framework to reduce expensive verifier calls in large language model (LLM) reasoning, particularly for multi-step symbolic tasks like MATH. It combines deterministic feasibility gating, hybrid pre-verification ranking, and adaptive allocation of verifier calls based on local uncertainty. The method significantly improves accuracy-cost trade-offs compared to best-of-N, majority voting, and beam search on the MATH benchmark, using 44% fewer verifier calls.

Adaptive Allocation on MATH Benchmark
The proposed method achieved 55.2% accuracy on the MATH benchmark while using an average of 44.8 verifier calls. This represents a 30% reduction in verifier calls and a 3.4% absolute accuracy improvement over the strongest baseline (Beam Search). The gains highlight the effectiveness of state-level, uncertainty-aware allocation in complex reasoning tasks, demonstrating that distributing verification where it is most informative significantly improves the accuracy-cost frontier.
