Church turing machine
WebA 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 … WebThe Church–Turing thesis states that any "computable" function that can be computed by a mathematician with a pen and paper using a finite set of simple algorithms, can be computed by a Turing machine. Hypercomputers compute functions that a Turing machine cannot and which are, hence, not computable in the Church–Turing sense.

There is this idea called the Church-Turing Thesis that says anything that can be computed somehow, can be computed using a Turing … WebThe Church-Turing thesis says that Turing Machines capture what computa-tion, or an algorithm, is: any reasonable model of computation can be translated into an equivalent computation with a Turing machine. We will thus identify ”algorithm” with a TM. 1.2 TM definition A Turing Machine is a 7-tuple, (Q,Σ,Γ,δ,q 0,q accept,q reject): 1.
