(Auto)formalization is supposed to be easy: Trellis process semantics for spelling out rigorous proofs
Researchers present Trellis, an autoformalization system that uses LLM agents within constrained workflows to convert natural language mathematical proofs into Lean formal code. The system achieves reliable formalization on modest computational budgets by enforcing incremental progress through iterative refinement, demonstrated by formalizing a recent Ramsey theory breakthrough.
