双向运动受限的有限自动机

Finite Automata With Restricted Two-Way Motion

David Damanik

摘要:

我们考虑有限的双向自动机,并通过计算接受计算中的左移次数来测量双向运动的使用。根据这一措施的自动机的限制,使我们能够详细研究使用双向运动接受正则语言的状态复杂性。给出了给定正则语言的双向谱。这个数量反映了如果双向运动的使用逐渐增加,最小接受装置的尺寸的变化。我们给出的例子光谱,证明统一的上限和下限,并研究其锐度。我们还获得了使用双向运动一致有界的双向自动机的状态复杂度结果。

英文摘要:

We consider finite two-way automata and measure the use of two-way motion by counting the number of left moves in accepting computations. Restriction of the automata according to this measure allows us to study in detail the use of two-way motion for the acceptance of regular languages in terms of state complexity. The two-way spectrum of a given regular language is introduced. This quantity reflects the change of size of minimal accepting devices if the use of two-way motion is increased incrementally. We give examples for spectra, prove uniform upper and lower bounds and study their sharpness. We also have state complexity results for two-way automata with uniformly bounded use of two-way motion.
