Now we come to the masterstroke of Turing machine theory – the Universal Turing machine. Suppose you have a Turing machine that computes something. It consists of a finite state machine, an initial ...
On Saturday, British mathematician Alan Turing would have turned 100 years old. It is barely fathomable to think that none of the computing power surrounding us today was around when he was born. But ...

What can't be computed? How Turing drew the line between the solvable and the impossible
Alan Turing didn't just define what machines could do — he set out to find where computation itself breaks down. This is the story of how a simple machine with a tape and a scanner became the boundary ...
The Turing machine can compute anything that can be computed. It is the very definition of computation and the fundamental tool for reasoning about computers. You really need to know what it is all ...
A mathematical model of computation. Named after English scientist Alan Turing, a Turing machine is a finite state machine that reads a tape divided into cells. The Turing machine examines the symbol ...
