Automatic Inference of Term Equivalence in Term Rewriting Systems

12 pagesPublished: June 19, 2013

Abstract

In this paper we propose a parametric technique to automatically infer algebraic property-oriented specifications from Term Rewriting Systems. Namely, given the source code of a TRS we infer a specification which consists of a set of most general equations relating terms that rewrite, for all possible instantiations, to the same set of normal forms.

The semantic-based inference method that we propose can cope with non-constructor-based TRSs, and considers non-ground terms. Particular emphasis is posed to avoid the generation of “redundant” equations that can be a logical consequence of other ones.

To experiment on the validity of our proposal we have considered an instance of the method employing a novel (condensed) semantics for left-linear TRSs and we have implemented a “proof of concept” prototype in Haskell which is available online.

Keyphrases: property-oriented specifications, semantics-based inference methods, Term Rewriting Systems
