Diversity in LLM mathematical reasoning is critical for exploration, but common diversity metrics mostly capture surface-level variation rather than differences in how a problem is solved. We address this gap by introducing approach-level diversity: variation in strategies across correct solutions to the same problem.

The paper proposes a new approach to large language model (LLM) reasoning that moves beyond naive repeated sampling. Instead of generating many independent solutions, it first samples problem‑specific concepts, hints, or strategies and conditions answer generation on them, producing a single trajectory of diverse concepts. A small concept generator is then trained via reinforcement learning to maximize downstream success, leading to significant improvements in pass@k on hard mathematical reasoning tasks compared to both naive sampling and concepts from larger untuned models, and the trained generator transfers to unseen answer generators, including those from different model families.

The paper introduces Self‑Routing, a post‑training framework that tailors optimization for each sample based on its rollout correctness and confidence. Instead of applying a single recipe to all data, samples are routed to different strategies—GRPO, on‑policy self‑distillation, regularization, or skipped—allowing training to adapt without external teachers or extra annotations. Experiments on Qwen3 and Qwen3.5 show consistent improvements over uniform methods and reveal that the routing distribution evolves during training, reducing unnecessary updates on low‑signal or already stable samples.
