WebA refinement type-based approach for the static verification of complex data structure invariants that reduces the manual annotation required to verify complex properties like … WebThe underlying type theory is a λ-calculus equipped with refinement types for expressing pre- and post-conditions within first-order logic. We derive formal cryptographic …
Web16. sep 2024 · The Workshop on Type-Driven Development (TyDe) aims to show how static type information may be used effectively in the development of computer programs. Co-located with ICFP, this workshop brings together leading researchers and practitioners who are using or exploring types as a means of program development. We welcome all … WebFirst-Order logic: First-order logic is another way of knowledge representation in artificial intelligence. It is an extension to propositional logic. FOL is sufficiently expressive to represent the natural language statements in a concise way. First-order logic is also known as Predicate logic or First-order predicate logic.
WebRefinement Types = Types + Predicates. That is, refinement types allow us to decorate types with logical predicates, which you can think of as boolean-valued Haskell …
