我们考虑的问题,建立一个程序综合问题isunrealizable(即,在给定的程序搜索空间中没有解)。以前的工作不可实现性开发了一些自动技术,建立一个问题是不可实现的,但是,这些技术都是黑盒,这意味着他们隐藏背后的推理whya综合问题是unrealizable.In本文中,我们提出了一个霍尔式推理系统,calledunrealizability logicfor建立一个程序综合问题是不可实现的。据我们所知,不可实现性逻辑是第一个证明系统,用于过度近似执行一组无限的命令式程序。该逻辑提供了一个通用的逻辑系统,用于构建关于不可实现性的可检查证明。类似于霍尔逻辑如何提炼算法和工具背后的基本概念来证明程序的正确性,不可实现逻辑将隐藏在能够确定程序合成问题是不可实现的先前工具中的基本概念提炼成一个单一的逻辑系统。
We consider the problem of establishing that a program-synthesis problem isunrealizable(i.e., has no solution in a given search space of programs). Prior work on unrealizability has developed some automatic techniques to establish that a problem is unrealizable; however, these techniques are allblack-box, meaning that they conceal the reasoning behindwhya synthesis problem is unrealizable.In this paper, we present a Hoare-style reasoning system, calledunrealizability logicfor establishing that a program-synthesis problem is unrealizable. To the best of our knowledge, unrealizability logic is the first proof system for overapproximating the execution of an infinite set of imperative programs. The logic provides a general, logical system for building checkable proofs about unrealizability. Similar to how Hoare logic distills the fundamental concepts behind algorithms and tools to prove the correctness of programs, unrealizability logic distills into a single logical system the fundamental concepts that were hidden within prior tools capable of establishing that a program-synthesis problem is unrealizable.
