一句话:提出一种更易使用的新型预言变量,并以更数学化的方式重新表述精化映射理论。
预言变量由 Abadi 和 Lamport 在《The Existence of Refinement Mappings》一文中引入,用于精化映射的存在性证明,但在实践中难以使用。本文提出一种新型预言变量,作者认为其使用起来简单得多。同时,文章将原文中的相关思想以更数学化的方式重新表述,使精化映射与预言变量的理论更清晰。摘要未给出实验评估;工作属于理论/方法层面的简化与重构。
Prophecy variables were introduced in the article “The Existence of Refinement Mappings” by Abadi and Lamport. They were difficult to use in practice. We describe a new kind of prophecy variable that we find much easier to use. We also reformulate ideas from that article in a more mathematical way.
