Coq

Coq is a formal proof management system used by mathematicians and computer scientists to verify the correctness of complex ideas, algorithms, and software. It provides a rigorous environment where you can define mathematical concepts and then create proofs that these ideas are true. The system checks each step automatically, ensuring that no logical errors remain. Essentially, Coq helps build highly reliable, bug-free code and models by applying precise mathematical reasoning, which is valuable in fields where correctness is critical, such as cryptography, aerospace, and formal verification.
