高阶方程模式反统一[预印本]

Higher-Order Equational Pattern Anti-Unification [Preprint]

David M. Cerna, Temur Kutsia

摘要:

我们认为反统一的简单类型的lambda项在联想,交换和联想交换理论,并制定了一个健全的和完整的算法,需要两个lambda项和计算其概括的形式,高阶模式。这个问题是有限的:最小的完整的推广集包含100多个元素。我们定义的最优解的概念,并调查特殊的片段的问题,最优解可以计算在线性或多项式时间。

英文摘要:

We consider anti-unification for simply typed lambda terms in associative, commutative, and associative-commutative 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 optimal solution and investigate special fragments of the problem for which the optimal solution can be computed in linear or polynomial time.
