Nuprl

Nuprl is a formal system and software framework that helps mathematicians and computer scientists verify the correctness of complex systems and programs. It uses a logical foundation called type theory to rigorously prove that a program does what it’s intended to do, reducing errors and increasing reliability. Essentially, Nuprl provides a structured way to specify, develop, and verify software and mathematical proofs, ensuring high confidence in their correctness before implementation or deployment.
