چکیده

In very recent work, we introduced a non-termination preserving transformation from logic programs with cut to definite logic programs. While that approach allows us to prove termination of a large class of logic programs with cut automatically, in several cases the transformation results in a non-terminating definite logic program. In this paper we extend the transformation such that logic programs with cut are no longer transformed into definite logic programs, but into dependency triple problems. By the implementation of our new method and extensive experiments, we empirically evaluate the practical benefit of our contributions.

Termination Analysis of Logic Programs with Cut Using Dependency Triples∗

In very recent work, we introduced a non-termination preserving transformation from logic programs with cut to definite logic programs. In this paper we extend the transformation such that logic programs with cut are transformed into dependency triple problems instead of definite logic programs. By the implementation of our new method and extensive experiments, we show that the power of automat...

Automated termination analysis for logic programs with cut

Termination is an important and well-studied property for logic programs. However, almost all approaches for automated termination analysis focus on definite logic programs, whereas real-world Prolog programs typically use the cut operator. We introduce a novel pre-processing method which automatically transforms Prolog programs into logic programs without cuts, where termination of the cut-fre...

Termination Analysis of Logic Programs Based on Dependency Graphs

This paper introduces a modular framework for termination analysis of logic programming. To this end, we adapt the notions of dependency pairs and dependency graphs (which were developed for term rewriting) to the logic programming domain. The main idea of the approach is that termination conditions for a program are established based on the decomposition of its dependency graph into its strong...

The Dependency Triple Framework for Termination of Logic Programs

We show how to combine the two most powerful approaches for automated termination analysis of logic programs (LPs): the direct approach which operates directly on LPs and the transformational approach which transforms LPs to term rewrite systems (TRSs) and tries to prove termination of the resulting TRSs. To this end, we adapt the well-known dependency pair framework from TRSs to LPs. With the ...

Goal-Directed and Relative Dependency Pairs for Proving the Termination of Narrowing

In this work, we first consider a goal-oriented extension of the dependency pair framework for proving termination w.r.t. a given set of initial terms. Then, we introduce a new result for proving relative termination in terms of a dependency pair problem. Both contributions put together allow us to define a simple and powerful approach to analyzing the termination of narrowing, an extension of ...
