The authors propose Graph-Based GRPO, an extension of Group Relative Policy Optimization that rewards structural validity, answer correctness, and node overlap with reference graphs.
Computational graphs replace free-form reasoning for verifiable LLM outputs
The Structural Chain-of-Thought method trains models to generate executable directed acyclic graphs, improving accuracy, efficiency, and faithfulness across multiple benchmarks.

In one line
Training LLMs to generate executable computational graphs improves accuracy, cuts reasoning length 5-6x, and increases faithfulness versus chain-of-thought.
