摘要

元胞自动机具有丰富的计算特性，同时提供了似是而非的物理计算模型。我们研究了这些自动机相空间中的可决性问题，这些自动机被解释为无限单词的自动结构。在一维，略多于一阶的理论是可判定的，但轨道谓词的加入导致不可判定。我们评论了这种“所见即所得”模式与缺乏自然中间度之间的联系。

Cellular Automata, Decidability and Phasespace

Cellular automata have rich computational properties and, at the same time, provide plausible models of physics-like computation. We study decidability issues in the phasespace of these automata, construed as automatic structures over infinite words. In dimension one, slightly more than the first order theory is decidable but the addition of an orbit predicate results in undecidability. We comment on connections between this “what you see is what you get” model and the lack of natural intermediate degrees.
