有限带宽和树深下的重构

Reconfiguration in bounded bandwidth and treedepth

Marcin Wrochna

摘要:

我们发现,几个已知的PSPACE-完全的重构问题仍然是如此,即使是有限的图形的有界带宽。关键的一步是注意到非常有限的字符串重写系统的相似性,其直接模拟图灵机的能力是经典的。这解决了在[Bonsma P.,2012年]。另一方面,我们表明,一大类的重新配置问题成为有界树深的图形上听话,这一结果是在某种意义上紧。

英文摘要:

We show that several reconfiguration problems known to be PSPACE-complete remain so even when limited to graphs of bounded bandwidth. The essential step is noticing the similarity to very limited string rewriting systems, whose ability to directly simulate Turing Machines is classically known. This resolves a question posed open in [Bonsma P., 2012]. On the other hand, we show that a large class of reconfiguration problems becomes tractable on graphs of bounded treedepth, and that this result is in some sense tight.
