重写策略的终止:一种通用方法

Termination of rewriting strategies: a generic approach

Isabelle Gnaedig, Helene Kirchner

摘要:

我们提出了一个通用的终止证明方法重写下的策略,基于一个明确的归纳终止属性。重写树的基础条款的证明树,交替应用缩小和抽象的步骤产生的模型。归纳原理是通过抽象机制来应用的,在抽象机制中,术语被表示其任何范式的变量所替换。归纳排序不是先验给出的,而是用排序约束定义的,在证明过程中递增设置。抽象约束可以用来控制收缩机制,众所周知,收缩机制很容易发散。然后为最内层、最外层和局部策略实例化泛型方法。

英文摘要:

We propose a generic termination proof method for rewriting under strategies, based on an explicit induction on the termination property. Rewriting trees on ground terms are modeled by proof trees, generated by alternatively applying narrowing and abstracting steps. The induction principle is applied through the abstraction mechanism, where terms are replaced by variables representing any of their normal forms. The induction ordering is not given a priori, but defined with ordering constraints, incrementally set during the proof. Abstraction constraints can be used to control the narrowing mechanism, well known to easily diverge. The generic method is then instantiated for the innermost, outermost and local strategies.
