Principles of ATP
Automated Theorem Proving involves the automated verification of mathematical proofs via computer programs. The current research frontier integrates Large Language Models (LLMs) with formal proof assistants to automate the discovery and verification of complex logical claims.
Modern Proof Assistants
- Lean: A functional programming language and theorem prover developed at Microsoft Research. It is a primary target for AI-driven mathematical reasoning (e.g., AlphaGeometry).
- Coq: A formal proof management system based on the Calculus of Inductive Constructions, facilitating mechanical proof checking.
- Isabelle/HOL: A generic interactive theorem prover utilized for formalizing mathematics and software verification.
Legacy and Specialized ATP Systems
- ACL2: An industrial-strength automated theorem prover for a subset of Common Lisp, used extensively for hardware verification at companies like AMD.
- PVS (Prototype Verification System): A high-level specification language and theorem prover based on higher-order logic.
- Mizar: One of the oldest projects for the formalization of mathematics, utilizing a human-readable proof language.
- Vampire: A high-performance automated theorem prover for first-order logic with equality.
AI and Formal Integration
The research focus is the use of LLMs to generate Formal Proof Scripts. Because proof assistants provide deterministic feedback, the generated reasoning is guaranteed to be mathematically sound if it successfully compiles within the assistant's kernel.

Objective
Automated theorem proving serves as a validation gate for high-stakes decision-making. The goal is to provide machine-verified proofs that autonomous system recommendations logically follow from provided evidence and constraints.
