Plan Then Action:High-Level Planning Guidance Reinforcement Learning for LLM Reasoning

Zhihao Dou, Qinjian Zhao, Zhongwei Wan +10

Large language models (LLMs) demonstrate strong reasoning abilities via Chain-of-Thought (CoT), but their token-level generation encourages local decisions and lacks global plannin…

Step-GRPO: Internalizing Dynamic Early Exit for Efficient Reasoning

Benteng Chen, Weida Wang, Shufei Zhang +2

Large reasoning models that use long chain-of-thought excel at problem-solving yet waste compute on redundant checks. Curbing this overthinking is hard: training-time length penalt…

PolyReal: A Benchmark for Real-World Polymer Science Workflows

Wanhao Liu, Weida Wang, Jiaqing Xie +12

Multimodal Large Language Models (MLLMs) excel in general domains but struggle with complex, real-world science. We posit that polymer science, an interdisciplinary field spanning…

Chem-R: Learning to Reason as a Chemist

Weida Wang, Benteng Chen, Di Zhang +14

Although large language models (LLMs) have significant potential to advance chemical discovery, current LLMs lack core chemical knowledge, produce unreliable reasoning trajectories…

CMPhysBench: A Benchmark for Evaluating Large Language Models in Condensed Matter Physics

Weida Wang, Dongchen Huang, Jiatong Li +32

We introduce CMPhysBench, designed to assess the proficiency of Large Language Models (LLMs) in Condensed Matter Physics, as a novel Benchmark. CMPhysBench is composed of more than…

DSADF: Thinking Fast and Slow for Decision Making

Zhihao Dou, Dongfei Cui, Jun Yan +5

Although Reinforcement Learning (RL) agents are effective in well-defined environments, they often struggle to generalize their learned policies to dynamic settings due to their re…
