Finite variant property
WebJun 27, 2024 · Let me first give a brief explanation of what variants and the finite variant property are, and then summarize the current state of the art about variant-based equational unification after . Details about narrowing are explained later, in Sect. 2.4. Variants in a Nutshell. WebThe goal of this paper is to give equivalent (resp. sufficient) conditions for the finite variant property and to systematically investigate this property for equational theories, which are relevant to security protocols verification. For instance, we prove that the finite variant property holds for Abelian Groups, and a theory of modular ...

WebAug 13, 2024 · An equational theory decomposed into a set B of equational axioms and a set Δ of rewrite rules has the finite variant (FV) property in the sense of Comon-Lundh and Delaune iff for each term t there is a finite set {t 1,..., t n} of → Δ,B-normalized instances of t so that any instance of t normalizes to an instance of some t i modulo B. This is a very … WebInspired by Comon and Delaune's notion of E-variant for a term, we propose a new narrowing strategy called variant narrowing that has a search space potentially much smaller than full narrowing, is complete, and yields a finitary E-unification algorithm when E has the finite variant property. We also discuss applications to symbolic ...
WebIn practice this has meant that most tools use a version of a technique known as variant unification. This requires, among other things, that the theory be decomposable into a set of axioms B and a set of rewrite rules R such that R has the finite variant property with respect to B.
