Mathematician Alan Turing invented an imaginary computer known as the Turing Machine; in an age before computers, he explored the concept of what it meant to be computable, creating the field of ...

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 ...

In computer science and blockchain technology, the term “Turing completeness” describes a system’s ability to carry out any computation that a Turing machine is capable of. A Turing machine is a ...

The brilliant English mathematician Alan Turing cracked German codes in WWII, revolutionized computer science—and foresaw the moral questions of modern technology. One of Alan Turing's many ...
