Instantaneous description of a turing machine
NettetA Turing machine is defined as follows. It has a one-dimensional tape, divided into squares. This tape extends infinitely to the left and to the right. Each square can store one character. The machine has a single I/O head that at any instant in time is “on” one of the squares. The control unit of the machine is defined by a set of abstract ...

NettetInstantaneous descriptions for Turing machines Instantaneous description of the TM’s state after some number of steps of computation: Current state, q. The contents of the tape, X 1X 2 ···X k. Surrounding it is an infinite number of blanks in both directions. The current position of the tape head. We will underline the current NettetThere are several models in use, but the most commonly examined is the Turing machine. Automata theory In theoretical computer science, automata theory is the study of abstract machines (or more appropriately, abstract 'mathematical' machines or systems) and the computational problems that can be solved using these machines.
A Turing machine is a mathematical model of computation describing an abstract machine that manipulates symbols on a strip of tape according to a table of rules. Despite the model's simplicity, it is capable of implementing any computer algorithm. The machine operates on an infinite memory tape … Se mer A Turing machine is a general example of a central processing unit (CPU) that controls all data manipulation done by a computer, with the canonical machine using sequential memory to store data. More specifically, it is … Se mer Following Hopcroft & Ullman (1979, p. 148), a (one-tape) Turing machine can be formally defined as a 7-tuple • Se mer Many machines that might be thought to have more computational capability than a simple universal Turing machine can be shown to have no more power (Hopcroft and Ullman p. 159, cf. … Se mer As Turing wrote in The Undecidable, p. 128 (italics added): It is possible to invent a single machine which can be used to compute any computable … Se mer The Turing machine mathematically models a machine that mechanically operates on a tape. On this tape are symbols, which the machine can read and write, one at a time, using a tape head. Operation is fully determined by a finite set of elementary … Se mer In the words of van Emde Boas (1990), p. 6: "The set-theoretical object [his formal seven-tuple description similar to the above] provides only … Se mer Early in his paper (1936) Turing makes a distinction between an "automatic machine"—its "motion ... completely determined by the configuration" and a "choice machine": ...whose motion is only partially determined by the … Se mer NettetInstantaneous Descriptions for TMs As with a PDA, we can also give an instantaneous description (ID) for a Turing Machine. An ID for a TM has the following form: 𝛼1 𝛼2. …
