Goedel-Architect: Streamlining Formal Theorem Proving with Blueprint Generation and Refinement

Jui-Hui Chung, Ziyang Cai, Zihao Li +14

We introduce Goedel-Architect, an agentic framework for formal theorem proving in Lean 4 centered on blueprint generation and refinement. A blueprint is a dependency graph of defin…
