在本文中,我们回顾了一些关于各种缩减策略的著名理论:标准化、最外层公平、共最终、Church-Rosser。定义此类策略的一个绊脚石是减少循环的存在,这可能会“困住”策略,因为它是无内存的。我们利用最近(重新)发现的事实,即当每个项具有范式时,正交重写系统中不存在归约循环,以增强一些策略定理,无论是在其范围还是在其正确性证明方面。
In this paper we review some well-known theory about reduction strategies of various kinds: normalizing, outermost-fair, cofinal, Church-Rosser. A stumbling block in the definition of such strategies is the presence of reduction cycles that may ‘trap’ a strategy as it is memory-free. We exploit a recently (re)discovered fact that there are no reduction cycles in orthogonal rewrite systems when each term has a normal form, in order to enhance some of the theorems on strategies, both with respect to their scope and the proof of their correctness.
