One of the problems with a classic Turing machine is the tape must be infinitely long. [Mark’s] Turing Ring still doesn’t have an infinite tape, but it does make it circular to save space. That along ...

Though as with so many independent inventors the origins of computing can be said to have been arrived at through the work of many people, Alan Turing is certainly one of the foundational figures in ...

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 ...

With regard to my previous blog on a One-bit processor and a mega-cool Turing machine, I’ve been bouncing around the Internet discovering all sorts of cool things… But before we hurl ourselves ...

Computational complexity and computability are central themes in theoretical computer science that address the fundamental question of what can be computed and at what cost. Computability theory ...
