Lean 4 Formalization Machine-Checks Dong-Yang Classification of Optimal (n,4) Binary Codes

Researchers produced a Lean 4 formal proof verifying Dong and Yang's classification of optimal finite-length (n,4) binary block codes for binary symmetric channels. The formalization was built largely by submitting the original paper's proofs to an AI tool. It illustrates both the promise and the current workflow of AI-assisted proof verification in coding theory.

StochBench: A Lean 4 Benchmark for Stochastic Processes in Formal Theorem Proving

Researchers have released StochBench, a Lean 4 benchmark containing 45 problems centered on stochastic processes. It was created because existing evaluations of language models in formal theorem proving rely heavily on small sets of competition-style problems, which do not reflect how such models perform on domain-specific mathematical fields.
