非终止性的二阶表述

A Second-Order Formulation of Non-Termination

Fred Mesnard, Etienne Payet

摘要:

我们考虑一类循环的终止/非终止性质。这样的循环是真实程序片段的常用抽象。二阶逻辑是表达非终止性的一种方便的语言。当然,这种性质一般是不可判定的。然而,通过将语言限制在已知的可判定的情况下,我们展示了新的循环类,其非终止性是可判定的。我们举了很多例子。

英文摘要:

We consider the termination/non-termination property of a class of loops. Such loops are commonly used abstractions of real program pieces. Second-order logic is a convenient language to express non-termination. Of course, such property is generally undecidable. However, by restricting the language to known decidable cases, we exhibit new classes of loops, the non-termination of which is decidable. We present a bunch of examples.
