1. Unlocking General Long Chain-of-Thought Reasoning Capabilities of Large Language Models via Representation Engineering (2025 · 19 citations)
   Reasoning models such as o1 and DeepSeek-R1 depend on long chains of thought (long CoTs) with planning, checking and backtracking. Earlier work showed this behaviour can be triggered with little data and carries over to new tasks. This paper asks whether long CoT is a general capability already present inside LLMs.
2. Rethinking Sample Polarity in Reinforcement Learning with Verifiable Rewards (2026 · 4 citations)
   This paper asks what positive (correct) and negative (incorrect) rollouts each contribute when large reasoning models are trained with RLVR.
3. RV-Syn: Rational and Verifiable Mathematical Reasoning Data Synthesis based on Structured Function Library (2026)
   RV-Syn tackles the shortage of reliable, complex mathematical training data for LLMs. Prior synthesis methods either rework existing annotated sets such as GSM8K and MATH, which limits diversity, or have a model write questions directly from documents or knowledge points. The authors argue that direct generation…
