一句话:构造 ℤ 上平移不变极大滤子,用以定义并分析带全局信息的激素元胞自动机模型。
本文研究 ℤ 上平移不变极大滤子的构造及其与激素元胞自动机的关系。激素元胞自动机是元胞自动机计算模型的一种推广,其中所有细胞共享关于全局状态的信息。作者首先设计平移不变极大滤子,以便定义这一新的计算模型;随后从不同假设出发,给出此类滤子的构造方法;最后分析由这些滤子诱导的元胞自动机模型的计算能力。
This paper deals with the construction of shift-invariant maximal filters on ℤ and their relation to hormonal cellular automata, a generalization of the cellular automata computation model with some information about the global state shared among all the cells. We first design shift-invariant maximal filters in order to define this new model of computation. Starting from different assumptions, we show how to construct such filters, and analyze the computation power of the induced cellular automata computation model.
