A modular order-sorted equational generalization algorithm
Generalization, also called anti-unification, is the dual of unification. Given terms t and t′, a generalization is a term t′′ of which t and t′ are substitution instances. The dual of a most general unifier (mgu) is that of least general generalization (lgg). In this work, we extend the known untyped generalization algorithm to, first, an order-sorted typed setting with sorts, subsorts, and su...
متن کاملHigher-Order Equational Unification via Explicit Substitutions
We show how to reduce the uniication problem modulo-conversion and a rst-order equational theory E, into a rst-order uni-cation problem in a union of two non-disjoint equational theories including E and a calculus of explicit substitutions. A rule-based uniica-tion procedure in this combined theory is described and may be viewed as an extension of the one initially designed by G. Dowek, T. Hard...
متن کاملHigher-Order Equational Pattern Anti-Unification [Preprint]
We consider anti-unification for simply typed lambda terms in associative, commutative, and associativecommutative theories and develop a sound and complete algorithm which takes two lambda terms and computes their generalizations in the form of higher-order patterns. The problem is finitary: the minimal complete set of generalizations contains finitely many elements. We define the notion of op...
متن کاملUTP2: Higher-Order Equational Reasoning by Pointing
We describe a prototype theorem prover, U·(TP)2, developed to match the style of hand-written proof work in the Unifying Theories of Programming semantical framework. This is based on alphabetised predicates in a 2nd-order logic, with a strong emphasis on equational reasoning. We present here an overview of the user-interface of this prover, which was developed from the outset using a pointand-...
