Generalization of verifier-guided adaptive test-time inference beyond mathematics

Determine whether the verifier-guided adaptive test-time inference framework for mathematical reasoning—comprising iterative trajectory generation with per-problem tool selection, compute strategy selection, and process reward model (PRM)-based step and trajectory scoring—generalizes to other non-mathematical domains; identify the domain-adaptive verification signals and broader evaluation protocols required to enable and validate such generalization.

Background

The paper proposes a verifier-guided adaptive test-time inference framework that treats reasoning as iterative trajectory generation and selection. For each problem, the agent plans, selects tools (e.g., Chain-of-Thought, self-reflection, numeric or logical verifiers), chooses a compute strategy (Best-of-N, beam search, or lookahead), and generates candidate trajectories. A process reward model (PRM) provides step-level correctness signals to guide pruning and expansion during generation and to select the final trajectory across iterations.

Empirical results demonstrate substantial gains in mathematical reasoning benchmarks (MATH-500, AIME24, AMO-Bench). However, the authors explicitly state that extending the approach to other domains is unresolved and likely requires domain-adaptive verification signals and broader evaluation, highlighting an open problem in generalization beyond mathematics.

Finally, while results are strong for mathematical reasoning, generalization to other domains remains open and will likely require domain-adaptive verification signals and broader evaluation.

First, the large-scale experiments focus on mathematical reasoning, so generalization to agentic, multimodal, or other long-horizon domains remains open.
