Simulation to Rules: A Dual-VLM Framework for Formal Visual Planning

Yilun Hao, Yongchao Chen, Chuchu Fan +1

Vision Language Models (VLMs) show strong potential for visual planning but struggle with precise spatial and long-horizon reasoning, while Planning Domain Definition Language (PDD…

R1-Code-Interpreter: LLMs Reason with Code via Supervised and Multi-stage Reinforcement Learning

Yongchao Chen, Yueying Liu, Junwei Zhou +5

Practical guidance on training Large Language Models (LLMs) to leverage Code Interpreter across diverse tasks remains lacking. We present R1-Code-Interpreter, an extension of a tex…

Code-as-Symbolic-Planner: Foundation Model-Based Robot Planning via Symbolic Code Generation

Yongchao Chen, Yilun Hao, Yang Zhang +1

Recent works have shown great potentials of Large Language Models (LLMs) in robot task and motion planning (TAMP). Current LLM approaches generate text- or code-based reasoning cha…

Planning Anything with Rigor: General-Purpose Zero-Shot Planning with LLM-based Formalized Programming

Yilun Hao, Yang Zhang, Chuchu Fan

While large language models (LLMs) have recently demonstrated strong potential in solving planning problems, there is a trade-off between flexibility and complexity. LLMs, as zero-…

CodeSteer: Symbolic-Augmented Language Models via Code/Text Guidance

Yongchao Chen, Yilun Hao, Yueying Liu +2

Existing methods fail to effectively steer Large Language Models (LLMs) between textual reasoning and code generation, leaving symbolic computing capabilities underutilized. We int…

Large Language Models Can Solve Real-World Planning Rigorously with Formal Verification Tools

Yilun Hao, Yongchao Chen, Yang Zhang +1

Large Language Models (LLMs) struggle to directly generate correct plans for complex multi-constraint planning problems, even with self-verification and self-critique. For example,…
