Turing Machine computability Alan Turing and used for computability theory proofs. It consists of an infinitely long "tape" with symbols (chosen from some finite set ) written at regular intervals. A pointer marks the current position and the machine is in one of a finite set of "internal states". At each step the machine reads the symbol at the current position on the tape. For each combination of current state and symbol read, a program specifies the new state and either a symbol to write to the tape or a direction to move the pointer (left or right) or to halt. In an alternative scheme, the machine writes a symbol to the tape *and* moves at each step. This can be encoded as a write state followed by a move state for the write-or-move machine. If the write-and-move machine is also given a distance to move then it can emulate an write-or-move program by using states with a distance of zero. A further variation is whether halting is an action like writing or moving or whether it is a special state. [What was Turing's original definition?]

Near Matches Ignore Exact Everything Turing Machine cooled by Lucy-S thing by rp Sun Mar 18 2001 at 15:50:01 A Turing machine is a mathematical construct . It models a machine that can be built in reality. The machine has a tape head that can read and/or write a symbol on a tape. It can also shift the tape one position to the left and to the right. At any time, the machine is in some internal state The machine's operation is defined by a finite set of transition s. A transition is specified by four items: a state , a symbol , another state , and an action . The transition is applicable whenever the machine is in the first state, and the head is on the specified symbol. It is applied by moving into the second state and performing the action. The action specifies either a move to the left, or a move to the right, or a symbol (to be written on the tape, overwriting whatever symbol was there). That's it. Anything that behaves according to these specifications is a Turing machine. The transitions completely define the machine's operation. Different Turing machines differ by having different transition tables. The set of transitions must be finite , implicitly restricting the set of internal states and the set of different symbols the machine can read or write to be finite as well.

skip to main skip to sidebar pSingularity A dialogue between a Seeker and a Sceptic on the Road to the Primordial Singularity - An interpretation of Advaita Vedanta from the perspective of Turing Machines and the Genome Friday, April 20, 2007 Posted by Prithwis Mukerjee at 12:29 PM 1 comments Links to this post Preface Sages and seers from time immemorial have held that the Truth is beyond reason, transcends the boundary of the physical world and can only be perceived at an intuitive level. Nevertheless, this particular effort seeks to reflect the Truth in the still waters of a dispassionate rational analysis. A rational approach, based on physical phenomena, may have many limitations but the desire to abandon it is an act of intellectual laziness. While it is true that many mystics have perceived the truth intuitively, it may be more satisfying to take the intuitive approach as a matter of choice and not of necessity. We have created a pattern of thoughts by connecting a number of apparently unrelated ideas, namely .. in a manner that is unique and has not been attempted in the past. Without being dogmatic and parochial about the greatness of the the Hindu relegion, we show how this ancient philosophy is not only relevent in the contemporary environment of rational science but how it has infact anticipated thoughts and ideas that have now appeared twelve hundred years later.

67. Alan Turing Een uitgebreid artikel over Alan Turing, n van de grondleggers van de informatica, en de door hem ontwikkelde Turing machines. http://users.compaqnet.be/stijn-heymans/Turing/AlanTuringnl.html

Alan Turing English version here Alan M. Turing (1912-1954) Alan Mathison Turing zag het levenslicht op 23 juni 1912 in Paddington bij Londen. Doordat zijn vader tot zijn pensioen in 1926 in India, toen nog Brits, werkte, groeide hij en z'n iets oudere broer voornamelijk in Engelse tehuizen op, waar expressie, originaliteit en creativiteit, niet echt aangemoedigd werden (wetenschappen was dus zeker uit den boze). Turing interesseerde zich echter w�l voor de exacte vakken en amuseerde zich toen al met chemische experimentjes. Van 1926 tot 1931 zat hij op een Engelse public school : Sherborne School, waar hij systematisch slechte punten haalde. Enkel voor wiskunde en andere wetenschapsvakken ging het beter, al waren de leerkrachten ook daar niet echt over te spreken (� His work is dirty �). Hij werd meer als een probleem voor de maatschappij beschouwd dan een toegevoegde waarde en ook in zijn verdere leven kreeg hij niet de waardering die hij verdiende. In 1931 sleept hij een studiebeurs in de wacht voor King's College, Cambridge. Van dan komt Turings carri�re in een stroomversnelling. In 1935 krijgt hij een ambt aan King's College. In 1936 krijgt hij de Smith's Price voor zijn werk in de kanstheorie. Hij lijkt af te stevenen op een succesvolle loopbaan als zuiver wiskundige. Z'n unieke geest drijft hem echter in een andere richting. In 1933 had Turing kennis gemaakt met Russel en Whitehead's "Principia Mathematica" en daarmee met het gebied van de wiskundige logica. Bertrand Russel was van mening dat alles wat wiskundig waar is men logisch kan afleiden met behulp van een welomlijnde verzameling afleidingsregels. Maar er waren sinds dan veel vragen gerezen over hoe waarheid door om 't even welk formalisme gevat kon worden. In het bijzonder had G�del in 1931 Russel's standpunt ontkracht door te tonen dat de wiskunde niet compleet is : er zijn ware stellingen over getallen die niet kunnen bewezen worden door de formele toepassing van deductieregels.

Automata theory From Wikipedia, the free encyclopedia Jump to: navigation search An example of automata and study of mathematical properties of such automata is automata theory In theoretical computer science automata theory is the study of abstract machines and the computational problems that can be solved using these abstract machines. These abstract machines are called automata. As suggested in figure, an automaton takes a symbol as input and " jumps " or transitions , from one state to another according to a transition function (which can be expressed as a table). This transition function tells the automaton which state to go to next given a current state and a current symbol . Automata are similar to finite state machines (FSM). Automata theory is closely related to formal language theory as the automata are often classified by the class of formal languages they are able to recognize. An automaton is considered to be a finite representation of a formal language that may be an infinite set.

About Turing machine (Topic) A Turing machine is an imaginary computing machine invented by Alan Turing to describe what it means to compute something. The ``physical description'' of a Turing machine is a box with a tape and a tape head. The tape consists of an infinite number of cells stretching in both directions, with the tape head always located over exactly one of these cells. Each cell has one of a finite number of symbols written on it. The machine has a finite set of states , and with every move the machine can change states, change the symbol written on the current cell, and move one space left or right . The machine has a program which specifies each move based on the current state and the symbol under the current cell. The machine stops when it reaches a combination of state and symbol for which no move is defined. One state is the

Home Background Details Gallery Prize Rules FAQs Background Universal Turing Machines Universal computation is perhaps the single most important idea of the past hundred years: it is what has made computers and most of modern technology possible. It could be that to do every different kind of computation would require a different kind of computeran adding machine for addition, multiplying machine for multiplying, and so on. But the crucial idea that emerged in the 1930s is that there can be a single universal computer that can just be programmed to do any possible computation. In other words, one can have a single piece of hardware, but just change the software (or the input) to get different computations done. Eventually, it became known that there are many possible kinds of universal computers, although it was not known how common they are until Wolfram's recent work for A New Kind of Science Turing machines were invented by Alan Turing in 1936, and were the first clear example of a system that could be a universal computer.
