autoformalization

Definition of autoformalization

1. : the automatic translation of mathematical statements, definitions, or proofs written in natural language into a formal language that a proof assistant such as Lean, Isabelle, or Coq can check

   • The research team used autoformalization to convert an informal olympiad proof into Lean before checking every logical step.
   • A fluent translation was not enough because the autoformalized theorem also had to preserve the meaning of the original statement.
