In computability theory, a system of data-manipulation rules (such as a model of computation, a computer's instruction set, a programming language, or a cellular automaton) is said to be Turing-complete or computationally universal if it can be used to simulate any Turing machine [1] [2] (devised by English mathematician and computer scientist Alan Turing).
A Turing machine is an idealised model 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. Typically, the sequential memory is represented as a tape of infinite length on which the machine can perform read and write operations.
Random-access Turing machines (RATMs) represent a pivotal computational model in theoretical computer science, especially critical in the study of tractability within big data computing scenarios. Diverging from the sequential memory access limitations of conventional Turing machines , RATMs introduce the capability for random access to memory ...
Theorem 2.2 There exists a Turing machine whose halting problem is recursively unsolvable. A related problem is the printing problem for a simple Turing machine Z with respect to a symbol S i ". A possible precursor to Davis's formulation is Kleene's 1952 statement, which differs only in wording: [19] [22]
Martin Davis makes a persuasive argument that Turing's conception of what is now known as "the stored-program computer", of placing the "action table"—the instructions for the machine—in the same "memory" as the input data, strongly influenced John von Neumann's conception of the first American discrete-symbol (as opposed to analog) computer—the EDVAC.
The "Total Turing test" [3] variation of the Turing test, proposed by cognitive scientist Stevan Harnad, [107] adds two further requirements to the traditional Turing test. The interrogator can also test the perceptual abilities of the subject (requiring computer vision ) and the subject's ability to manipulate objects (requiring robotics ).
SAN FRANCISCO (Reuters) - - Artificial intelligence data startup Turing, one of a growing number of companies that provide human trainers to AI labs, said Tuesday its revenue tripled to $300 ...
Computation is commonly understood in terms of Turing machines which manipulate symbols according to a rule, in combination with the internal state of the machine. The critical aspect of such a computational model is that we can abstract away from particular physical details of the machine that is implementing the computation. [ 5 ]
