  • Declaratively, guarded Horn clauses are read as ordinary logical implications:
  • Quasiidentities are special type of Horn clauses.
  • Examples of refutation-complete systems include : SLD resolution on Horn clauses, clause sets.
  • He also developed the minimal model and the fixpoint semantics of Horn clauses with Maarten van Emden.
  • The core of Visual Prolog are Horn clauses, algebraic datatypes, pattern matching and controlled strongly and statically typed.
  • Horn clauses are of interest because they are able to express implication of one variable from a set of other variables.
  • Despite its simplicity compared with classical logic, this combination of Horn clauses and negation as failure has proved to be surprisingly expressive.
  • However, he is best known for his contributions to the development of logic programming, starting with the procedural interpretation of Horn clauses.
  • This is pretty much universally accepted in formal logic, especially in the context of satisfiability, horn clauses, resolution and similar stuff.
  • Its foundation is Horn clause logic with equality which consists of predicates and Horn clauses for logic programming, and functions and equations for functional programming.
  • KL1 is an implementation of Flat GHC ( a subset of the Guarded Horn Clauses language by Kazunori Ueda ), making it a parallelised Prolog variant.
  • In the simplest case in which H, B 1, &, B n are all atomic formulae, these clauses are called definite clauses or Horn clauses.
  • Unit propagation, applied repeatedly as new unit clauses are generated, is a complete satisfiability algorithm for sets of propositional Horn clauses; it also generates a minimal model for the set if satisfiable : see Horn-satisfiability.
  • It also inspired the concurrent logic programming language Guarded Horn Clauses ( GHC ) by Ueda, which was the basis of KL1, the programming language that was finally designed and implemented by the FGCS project as its core programming language.
  • It also became clear that such clauses could be restricted to definite clauses or Horn clauses, where H, B 1, &, B n are all atomic predicate logic formulae, and that SL-resolution could be restricted ( and generalised ) to LUSH or SLD-resolution.
