禁止模式重写的终止与自动合成

Termination of Rewriting with and Automated Synthesis of Forbidden Patterns

Bernhard Gramlich, Felix Schernhammer

摘要:

我们介绍了一个修改后的版本,著名的依赖对框架,是适合于禁止模式限制下的重写终止分析。通过将上下文附加到表示相应递归函数调用的调用上下文的依赖对,可以将禁止模式限制合并到依赖对链的(适应的)概念中,从而产生可靠且完整的终止分析方法。建立在这个上下文依赖对框架,我们引入了一个依赖对处理器,通过分析依赖对的上下文信息,简化了问题。此外,我们展示了如何使用这个处理器来合成禁止模式适合于一个给定的长期重写系统的飞行在终止分析。

英文摘要:

We introduce a modified version of the well-known dependency pair framework that is suitable for the termination analysis of rewriting under forbidden pattern restrictions. By attaching contexts to dependency pairs that represent the calling contexts of the corresponding recursive function calls, it is possible to incorporate the forbidden pattern restrictions in the (adapted) notion of dependency pair chains, thus yielding a sound and complete approach to termination analysis. Building upon this contextual dependency pair framework we introduce a dependency pair processor that simplifies problems by analyzing the contextual information of the dependency pairs. Moreover, we show how this processor can be used to synthesize forbidden patterns suitable for a given term rewriting system on-the-fly during the termination analysis.
