Several alternative semantics have been put forward, exposing operational details of the computation state. We propose instead to redesign Prolog around structured alternatives to the cut and clauses, keeping the expressive power and computation model but with a compositional denotational semantics over much simpler states—just variable :// We present an operational model O and a continuation based denotational model D for a uniform variant of PROLOG, including the cut operator.

Section 4 discusses the semantics of Prolog with cut. Section 5 applies the semantics to validate two optimizing transformations of Prolog programs, and Section 6 concludes the paper. Appendices 1 and 2 contain the proofs of equivalence between the denotational and operational semantics for the cut-free and the cut cases respectively.

We present a new operational semantics for Prolog which covers all constructs in the corresponding ISO standard (including “non-logical” concepts like cuts, meta-programming, “all solution” predicates, dynamic predicates, and exception handling).

In contrast to the classical operational semantics for logic programming, our semantics is linear and not The operational semantics of the quantum while-language is carefully presented, and the denotational semantics of quantum while-programs is systematically investigated.

For convenience of the reader, the basics of lattice theory and domain theory needed in defining the denotational semantics are briefly :// In this paper we propose a denotational semantics for Prolog and an approach to the abstract interpretation of Prolog programs; we deal with the control rules of Prolog and the cut :// Moreover, the equivalence of this denotational semantics and an operational semantics for Prolog is a straightforward generalization for the congruence proof of B.

Secondly, our denotational semantics uses continuations. This has several advantages over earlier semantics which (essentially) are based on a direct approach. (See [Br] for a ?doi=&rep=rep1&type=pdf.
