Constraint-First Reasoning: A Training-Free Protocol for Exploiting Answer-Space Constraints in Mathematical Problem Solving

Hongbo Ma, Bangji Yang, Yunqian Selina Cheng +3

Large language models can derive a plausible mathematical object yet still violate explicit requirements--for example, by omitting a modular reduction, returning a non-integer, or…

The Many Faces of On-Policy Distillation: Pitfalls, Mechanisms, and Fixes

Siqi Zhu, Xuyan Ye, Hongyu Lu +2

On-policy distillation (OPD) and on-policy self-distillation (OPSD) have emerged as promising post-training methods for large language models, offering dense token-level supervisio…

Retrieval is Cheap, Show Me the Code: Executable Multi-Hop Reasoning for Retrieval-Augmented Generation

Jiashuo Sun, Jimeng Shi, Yixuan Xie +10

Retrieval-Augmented Generation (RAG) has become a standard approach for knowledge-intensive question answering, but existing systems remain brittle on multi-hop questions, where so…

Batched Contextual Reinforcement: A Task-Scaling Law for Efficient Reasoning

Bangji Yang, Hongbo Ma, Jiajun Fan +1

Large Language Models employing Chain-of-Thought reasoning achieve strong performance but suffer from excessive token consumption that inflates inference costs. Existing efficiency…

ProteinZero: Self-Improving Protein Generation via Online Reinforcement Learning

Ziwen Wang, Jiajun Fan, Ruihan Guo +3

Protein generative models have shown remarkable promise in protein design, yet their success rates remain constrained by reliance on curated sequence-structure datasets and by misa…
