单带线性时间图灵机理论

Theory of One Tape Linear Time Turing Machines

Kohtaro Tadaki, Tomoyuki Yamakami, Jack C. H. Lin

摘要:

单带(单头)线性时间图灵机理论与多项式时间图灵机理论有本质的不同,因为这些机器与有限状态自动机密切相关。本文讨论了各种类型的单带图灵机的结构复杂性问题(确定性,非确定性,可逆,交替,概率,计数和量子图灵机),停止在线性时间,其中机器的运行时间被定义为任何最长计算路径的长度。我们探讨了单带线性-计算图灵机的时间,并阐明机器的资源如何影响它们的计算模式和能力。

英文摘要:

A theory of one-tape (one-head) linear-time Turing machines is essentially different from its polynomial-time counterpart since these machines are closely related to finite state automata. This paper discusses structural-complexity issues of one-tape Turing machines of various types (deterministic, nondeterministic, reversible, alternating, probabilistic, counting, and quantum Turing machines) that halt in linear time, where the running time of a machine is defined as the length of any longest computation path. We explore structural properties of one-tape linear-time Turing machines and clarify how the machines' resources affect their computational patterns and power.
