Modeling Reality with Mathematicsor .-unification. The concept of .-unification comes up naturally when we apply the Skolem-Herbrand-Gödel theorem to a set of universal Horn clauses with equality, in order to reduce unsatisfiability in the first-order case to unsatisfiability in the ground case. Recall that this theorem states that

Introduction,which are important in computer science. In the context of programming languages, a definite clause of the form ..,..., .. is viewed as a definition of the procedure . in terms of the subprocedures ..,...,.., and a negative clause of the form ← ..,..., .., is viewed as a sequence of procedure calls.

Preliminaries,attempts to be as concise as possible, and the reader is referred to a standard text in logic, such as Gallier , for a more thorough presentation. Lloyd or Apt is the accepted introduction to the theory of logic programming. The reader is invited to skip this chapter if and until it is

Soundness and Completeness Results I,ll follow the following guideline in showing these results. First, the method in the ground case is presented and proved complete. Then first-order extension outlined in the previous chapter is shown to be complete by appealing to the completeness of the ground case and the Skolem-Herbrand-Gödel the

An Equational Extension,e is the so-called problem of equality and functions. The underlying deduction mechanism for Prolog, .-resolution, is defined only for languages without equality. As mentioned in chapter 1, current Prolog systems include a collection of interpretations of the equality symbol which are basically inhe
