求解无递归Horn子句的广义插值

Generalised Interpolation by Solving Recursion-Free Horn Clauses

Ashutosh Gupta, Corneliu Popeea, Andrey Rybalchenko

摘要:

在本文中,我们提出了InterHorn,无递归Horn子句的求解器。InterHorn的主要应用领域在于解决软件验证中出现的插值问题。我们展示了如何一系列的插值问题,包括路径,过渡,嵌套,状态/过渡和良好的插值可以直接由InterHorn处理。通过详细说明这些插值问题和他们的霍恩子句表示,我们希望鼓励出现一个共同的后端插值接口有用的不同的验证工具。

英文摘要:

In this paper we present InterHorn, a solver for recursion-free Horn clauses. The main application domain of InterHorn lies in solving interpolation problems arising in software verification. We show how a range of interpolation problems, including path, transition, nested, state/transition and well-founded interpolation can be handled directly by InterHorn. By detailing these interpolation problems and their Horn clause representations, we hope to encourage the emergence of a common back-end interpolation interface useful for diverse verification tools.
