By Mike Gordon. Abstract. HOL is a computer system for generating proofs in a version of higher order logic derived from Church's simple theory of types.

This paper is the original description of the logic underlying the HOL system. Since it was written the system has changed Author: Mike Gordon. Abstract. HOL is a version of Robin Milner’s LCF theorem proving system for higher-order logic. It is currently being used to investigate (1) how various levels of hardware behaviour can be rigorously modelled and (2) how the resulting behavioral representations can be the basis for verification by mechanized formal by: The HOL system is a higher order logic theorem proving system implemented at Edinburgh University, Cambridge University and INRIA.

Its many applications, from the verification of hardware designs at all levels to the verification of programs and communication protocols are considered in depth in this volume. In Part I, they show that typed lambda-calculi, a formulation of higher-order logic, and cartesian closed categories, are essentially the same.

Part II demonstrates that another formulation of higher-order logic, (intuitionistic) type theories, is closely related to topos theory.

Part III is devoted to recursive by: 71 A Sequent Formulation of a Logic of Predicates in HOL Ching-Tsun C h o u 1 () C o m p u t e r Science Department, University of California at Los Angeles, Los Angeles, CAU.S.A.

So far, machine learning has generally not been used to ﬁlter or generate these steps. In this paper, we introduce a new dataset based on Higher-Order Logic (HOL) proofs, for the purpose of de-veloping new machine learning-based theorem-proving strategies.

This is followed by an explanation of the theorem-proving infrastructure provided by HOL. Finally two appendices contain a subset of the reference manual, and an overview of the HOL library, including an example of an actual library : Hardcover.

“The book is highly recommended for learning and teaching theorem proving and semantics, picking up a lot of useful knowledge on higher-order logic along the way.

The book is well-structured and written to support learning about the two main by: comes from using higher-order terms and higher-order rules, thus avoiding the overhead of issues like name binding and scoping which typically plague implementations. This book builds up the ideas behind Lambda Prolog progressively starting with traditional Prolog (presented as a logic) and then adding in more powerful by: The HOL interactive theorem prover is a proof assistant for higher-order logic: a programming environment in which theorems can be proved and proof tools implemented.

Built-in decision procedures and theorem provers can automatically establish many simple theorems (users may have to prove the hard theorems themselves!).

We devise a shallow semantical embedding of Åqvist's dyadic deontic logic E in classical higher-order logic. This embedding is shown to be faithful, viz. sound and complete. The B-book: assigning programs to meanings.

HOL: A Machine Oriented Formulation of Higher Order Logic. HOL: A Machine Oriented Formulation of Higher Order Logic, Isabelle Logics: ().Author: Michael Butler and Issam Maamria. It is argued that techniques for proving the correctness of hardware designs must use abstraction mechanisms for relating formal descriptions at different levels of detail.

Four such abstraction mechanisms and their formalisation in higher order logic are discussed. Gordon, M.J.C., ‘HOL: A Machine Oriented Formulation of Higher Order Cited by: In mathematics and logic, a higher-order logic is a form of predicate logic that is distinguished from first-order logic by additional quantifiers and, sometimes, stronger -order logics with their standard semantics are more expressive, but their model-theoretic properties are less well-behaved than those of first-order logic.

Now one may wonder if the type system λHOL is really faithful to higher order predicate logic differently, one can ask the question of completeness: given a proposition of HOL such that Γ φ ⊢ M: ([φ]) in λHOL, is φ derivable in HOL.

It turns out that this is the case. State of the art — yes, so far as I know all algorithms more or less take the same shape as Huet's (I follow theory of logic programming, although my expertise is tangential) provided you need full higher-order matching: subproblems such as higher-order matching (unification where one term is closed), and Dale Miller's pattern calculus, are decidable.

HOL (Higher Order Logic) denotes a family of interactive theorem proving systems using similar (higher-order) logics and implementation strategies. Systems in this family follow the LCF approach as they are implemented as a library in some programming language.
