They provide a precise formal de64257nition of what it means for a function to be computable Many other de64257nitions of computation have been proposed over the years for example one could try to formalize precisely what it means to run a program. A Turing machine is a primitive yet general computer with an in64257nite tape In each cycle the control unit reads the current tape symbol writes a symbol on the tape moves one position to the left or right and switches to the next state The last th They provide a precise formal de64257nition of what it means for a function to be computable Many other de64257nitions of computation have been proposed over the years for example one could try to formalize precisely what it means to run a program CS3231, 2010-2011.

The Turing Test Minds & Machines Alan Turing British mathematician known for: Turing Machines (1936) Breaking German Enigma (WWII) Turing Test (1950) ? “I propose to consider the question, 'Can machines think?' This should begin with definitions of the meaning of the terms 'machine 'and 'think'. … [But] Instead of attempting such a definition I shall replace the question by another... The new form of the problem can be described in terms of a game which we call the 'imitation game'.“
