用实时元胞自动机模拟不经意多头单向有限自动机

A Simulation of Oblivious Multi-Head One-Way Finite Automata by Real-Time Cellular Automata

Alex Borello

摘要:

在本文中,我们提出了一个简单的模拟,但显着强大的,顺序模型的元胞自动机。模拟模型被称为不经意多头单向有限自动机,其特征在于其头部仅向前移动,其轨迹仅取决于输入的长度。虽然原始的有限自动机在线性时间内工作,但其对应的元胞自动机实时执行相同的任务,即精确地执行输入的长度。虽然不是真正的加速,模拟可能是有趣的,并提醒我们关于元胞自动机的线性和实时的等价性的开放问题。

英文摘要:

In this paper, we present the simulation of a simple, yet significantly powerful, sequential model by cellular automata. The simulated model is called oblivious multi-head one-way finite automata and is characterized by having its heads moving only forward, on a trajectory that only depends on the length of the input. While the original finite automaton works in linear time, its corresponding cellular automaton performs the same task in real time, that is, exactly the length of the input. Although not truly a speed-up, the simulation may be interesting and reminds us of the open question about the equivalence of linear and real times on cellular automata.
