FormalEvolve: Neuro-Symbolic Evolutionary Search for Diverse Autoformalization

FormalEvolve is a neuro‑symbolic evolutionary search framework that treats autoformalization as a budgeted test‑time search problem. It builds a compilation‑feasible archive of formal statements and expands it using LLM‑driven mutation, crossover, bounded patch repair, and symbolic AST rewrites to generate diverse, semantically accepted formalizations. In experiments on CombiBench and ProofNet, FormalEvolve achieves higher SH@100 scores and improves theorem‑complete proving under fixed prover budgets compared to no‑archive baselines.

TopoAlign: A Framework for Aligning Code to Math via Topological Decomposition

The paper introduces TopoAlign, a framework that repurposes code repositories to train Math LLMs by decomposing code into docstrings, main functions, and dependency functions and reassembling them into structures that mirror formal mathematical statements. Using this approach, the authors train three state‑of‑the‑art models—DeepSeek‑Math, Qwen‑3, and Herald—and evaluate them on MiniF2F, Putnam, and ProofNet benchmarks. TopoAlign yields significant performance gains, notably a 17.77% improvement on BEq@10 and a 68.82% boost on typecheck@10 for DeepSeek‑Math, while also providing modest gains for Herald.

Backward through Time, Algebraically

The paper introduces a differentiable evaluation engine for linear temporal logic (LTL) that is algebra‑generic and suitable for training soft‑valued systems such as neural policies and adaptive controllers. It presents an executable specification of the algebras it can accept, implements several algebras, and audits their forward and backward behavior, all within the PyTorch library telos.
