As such it is still widely used in theoretical computer science , especially in complexity theory and the theory of computation .

(Interestingly, a seemingly minor relaxation enables the Turing machine to perform such a wide variety of computations that it can serve as a model for the computational capabilities of all modern computer software.) More precisely, a Turing machine consists of:

ISCID Encyclopedia of Science and Philosophy BETA Make Entry Become an Editor Most Popular: ( Help Turing Machine The concept of the Turing Machine made its debut in 1956 and was the brainchild of the renowned mathematician Alan Turing . It was an abstract or theoretical computer that had as its purpose the provision of a mathematically exact definition of an algorithm and succeeded in providing it by means of certain set of finite components such as a set of instructions, a set of internal states and an alphabet that contained a blank symbol. The Turing Machine is still relevant today and is one of the primary abstractions that are used by the modern theories of computability (ie. the theories of what computers are capable and not capable of doing) and theories regarding complexity and computation. The modern computer comes very close to instantiating Turing’s vision, by implementing a simple set of instructions to achieve an extraordinary set of computing power. A Turing Machine is not a complex kind of computer, but is in fact quite simple and restricted in its operational capacities to the reading and writing of symbols on a tape of infinite length (one that is split up into cells), or to traveling along the tape, one cell at a time, either to the left or to the right according to a simple set of rules. The state of a Turing Machine at any point in time can be interpreted semantically so as to indicate meaningful results of an algorithm. The advent of artificial intelligence (especially the so-called Strong AI) was heavily influenced by the view that human beings may be something like a Universal Turing Machine. If this view is correct, then it should be possible to actually recreate salient human qualities, such as rationality and intelligence. The prospect that human beings were nothing but UTMs led to what has been called Computationalism in the

Initially the tape has the input string on it, followed by an infinite number of blank symbols ( ), and the head is at the left end of the tape. At each step we use the transition function to determine the next state, the symbol written on the tape just prior to moving, and the direction to move the head, left (L) or right (R). If we ever reach a final state, the machine halts. For simplicity, we will assume that the tape alphabet has the fixed size 2

Turing machines are not intended as a practical computing technology, but rather as a thought experiment representing a computing machine. They help computer scientists understand the limits of mechanical computation. A succinct definition of the thought experiment was given by Turing in his 1948 essay, "Intelligent Machinery". Referring back to his 1936 publication, Turing writes that the Turing machine, here called a Logical Computing Machine, consisted of: ..."an infinite memory capacity obtained in the form of an infinite tape marked out into squares on each of which a symbol could be printed. At any moment there is one symbol in the machine; it is called the scanned symbol. The machine can alter the scanned symbol and its behavior is in part determined by that symbol, but the symbols on the tape elsewhere do not affect the behavior of the machine. However, the tape can be moved back and forth through the machine, this being one of the elementary operations of the machine. Any symbol on the tape may therefore eventually have an innings." (Turing 1948, p. 61)

Turing, writing before the invention of the modern digital computer, was interested in the question of what it means to be computable. Intuitively a task is computable if one can specify a sequence of instructions which when followed will result in the completion of the task. Such a set of instructions is called an effective procedure , or algorithm , for the task. This intuition must be made precise by defining the capabilities of the device that is to carry out the instructions. Devices with different capabilities may be able to complete different instruction sets, and therefore may result in different classes of computable tasks (see the entry on computability and complexity Turing proposed a class of devices that came to be known as Turing machines. These devices lead to a formal notion of computation that we will call

Algebra Applied Mathematics Calculus and Analysis Discrete Mathematics ... Interactive Demonstrations Turing Machine A Turing machine is a theoretical computing machine invented by Alan Turing (1937) to serve as an idealized model for mathematical calculation. A Turing machine consists of a line of cells known as a "tape" that can be moved back and forth, an active element known as the "head" that possesses a property known as "state" and that can change the property known as "color" of the active cell underneath it, and a set of instructions for how the head should modify the active cell and move the tape (Wolfram 2002, pp. -81). At each step, the machine may modify the color of the active cell, change the state of the head, and then move the tape one unit to the left or right. Turing machines are implemented in Mathematica as TuringMachine A generalization of the Turing machine in which the head is allowed to move steps in either direction was considered by Macura (2005). A template for specifying a 3-state, 2-color Turing machine is shown above using a form of notation due to Wolfram (2002). In this figure, a state is represented by a square containing a pointer indicating any of three possible directions; the property of 'color' is represented by the color of the square; and an instruction is represented by two squares in a column, with the top one representing a possible color and state of the active cell and the bottom one giving the new state and color of the active cell together with the direction the tape should be moved. The special state (with no pointer) indicates a state at which the Turing machine should halt, i.e., cease computation.
