43. The Steam-Powered Turing Machine The SteamPowered turing machine. The Steam-Powered turing machine mural was painted on a stairwell wall of Sieg Hall in 1987 by http://www.cs.washington.edu/general/sptm-caption.html

The Steam-Powered Turing Machine The "Steam-Powered Turing Machine" mural was painted on a stairwell wall of Sieg Hall in 1987 by a dozen first-year graduate students seeking diversion on the eve of the qualifying examination. The SPTM was originally conjured up a few years before this by Professor Alan Borning. Borning was undertaking a revision of the graduate program brochure. Professor Larry "Tomorrow" Ruzzo was late with his biographical information for the brochure real late. In desperation, Borning threatened to provide text himself if Ruzzo failed to come through. The threat didn't work, and when the printing deadline arrived, Borning followed through that year's graduate brochure carried the following description of Ruzzo's research interests: "Currently, his principal research project involves the construction and programming of a vaguely parallel computer, consisting of 32 steam-powered Turing machines installed in the basement of Sieg Hall. Of particular interest is the use of triple-expansion bypass valves, coupled to individual governors on each engine, to achieve write-synchronization of the machines. Graduate students have played an important role in the construction and operation of the engine, particularly in stoking the boilers, and advanced undergraduates are occasionally allowed to polish the brass gauges. "Originally intended as a general computing engine, restrictions imposed by the Pollution Control and Noise Abatement Boards require that only algorithms running in polynomial time may be used. The project recently suffered another setback when one of Professor Ruzzo's graduate students slipped on a mouldering stack of ungraded homework exercises and fell under the write head of one of the machines. Now permanently embossed with a series of 1's and 0's, the student is suing to have the machine dismantled."

44. Dictionary Of Philosophy Of Mind - Turing Machine turing machine A simple mechanical device consisting solely of a tape, a read/write head, and a finite state machine. Turing was http://www.artsci.wustl.edu/~philos/MindDict/turingmachine.html

Turing machine A simple mechanical device consisting solely of a tape, a read/write head, and a finite state machine. Turing was able to show that this machine is able to perform all the operations a person working with a logical system would be able to perform. The Turing machine has had a central role in theories of computation and computability since the mid 1930s when they were introduced as a rigorous means of defining the concept of 'method' (or algorithm) by Alan Turing . The machine itself is quite simple: it consists solely of a tape, a read/write head and a table of state changes. The tape is divided into discrete boxes, each of which may have either a zero or a one in it. The head will read or write a zero or one, depending on the current state and what is in the current tape-square which the head reads. Despite the simplicity of this idea, it lays all the foundations for understanding the modern computer and computation in general. Turing was able to show that the Turing machine was a mechanical process that was able to perform all the operations a person working with a logical system would be able to perform. Alonzo Church , in reference to Turing's work, formulated what is now referred to as the Church-Turing thesis; namely, that all definitions of computability are equivalent (i.e. Turing machine computable functions are all the computable functions there are). In other words, Turing machines can compute any function that is computable, assuming that both the tape and time are infinite.

Computable and uncomputable functions Turing first described the Turing machine in an article published in 1936, 'On Computable Numbers, with an Application to the Entscheidungsproblem', which appeared in Proceedings of the London Mathematical Society (Series 2, volume 42 (1936-37), pp. 230-265). The head and the tape A Turing machine is an idealised computing device consisting of a read/write head (or 'scanner') with a paper tape passing through it. The tape is divided into squares, each square bearing a single symbol'0' or '1', for example. This tape is the machine's general purpose storage medium, serving both as the vehicle for input and output and as a working memory for storing the results of intermediate steps of the computation. The input that is inscribed on the tape before the computation starts must consist of a finite number of symbols. However, the tape is of unbounded lengthfor Turing's aim was to show that there are tasks that these machines are unable to perform, even given unlimited working memory and unlimited time. A Turing machine The read/write head is programmable. It is be helpful to think of the operation of programming as consisting of altering the head's internal wiring by means of a plugboard arrangement. To compute with the device, you program it, inscribe the input on the tape (in binary or decimal code, say), place the head over the square containing the leftmost input symbol, and set the machine in motion. Once the computation is completed, the machine will come to a halt with the head positioned over the square containing the leftmost symbol of the output (or elsewhere if so programmed).

Labs for The Most Complex Machine xTuringMachine Lab: Introduction to Turing Machines T URING MACHINES are extremely simple calculating devices. A Turning machine remembers only one number, called its state . It moves back and forth along an infinite tape, scanning and writing symbols and changing its state. Its action at a given step in the calculation is based on only two factors: its current state number and the symbol that it is currently scanning on the tape. It continues in this way until it enters a special state called the halt state . In spite of their simplicity, Turing machines can perform any calculation that can be performed by any computer. In fact, certain individual Turing machines, called universal Turing machines , can actually execute arbitrary programs, just as a computer can. You won't see any universal Turing machines in this lab, but you will experiment with Turing machines that can perform non-trivial calculations. Turing machines are covered in Chapter 4 of The Most Complex Machine. Although the lab is mostly self-contained, it would be useful for you to have some familiarity with Turing machines before beginning the lab. Especially important is the idea that a Turing machine is described by a

The xTuringMachine Applet T URING MACHINES are very simple computational devices. A Turing machine has an infinitely long tape, divided into cells . Each cell can be blank or can contain a symbol chosen from some fixed finite list. The Turing machine moves along the tape reading and writing symbols. It has an internal state , which can be either the halt state or an integer between zero and some specified maximum value. When a Turing machine enters the halt state, it stops computing. Although Turing machines are very simple, any computation that can be done by any computer can also be done by some Turing machine. The action that a Turing machine takes depends only on its state and on the symbol displayed in the cell where the machine is currently located. Given this information, the Turing machine takes three actions: It writes a symbol to the cell (possibly the same one that is already there); it moves one cell to the left or one cell to the right; and it sets its internal state (possibly to the same state that it is currently in). The Turing machine has a table of rules that tells it what to do for various combinations of its current state and the symbol it reads from the current cell.

Fundamental Computer Science Up Turing Machines Turing bedacht zijn Turing Machines als antwoord op de vraag wat een methode is. Turing Machines zijn gebaseerd op het volgende idee hierover. De rekenaar Iemand die een probleem oplost, de "rekenaar", heeft beschikking over potlood en papier. Er is een ongelimiteerde hoeveelheid papier beschikbaar. Op ieder moment kan de rekenaar één symbool opschrijven op het papier voor zich. De rekenaar kan lezen welk symbool op het papier voor zich staat. Na iedere schrijfactie kan zij besluiten om het volgende papiertje of het vorige papiertje te pakken, of het huidige papiertje te laten liggen. Deze eigenschappen van het "rekenproces" zijn natuurlijk geïdealiseerd. In de praktijk heb je nooit een ongelimiteerde hoeveelheid papier. De papiervoorraad in de wereld is beperkt. De rekenaar kan slechts één symbool op een papiertje schrijven. Niet erg economisch maar wel een duidelijke afspraak. Verder kan de rekenaar slechts teruglezen door één voor één de vorige papiertjes te pakken totdat het gezochte papiertje is gevonden. De vraag die we nu moeten beantwoorden is "Hoe bepaalt de rekenaar welk symbolen ze op de papiertjes schrijft?"
