In computational complexity theory, P and NP are two classes of problems. P is the class of decision problems that a deterministic Turing machine can solve in polynomial time. In useful terms, any ...

Memcomputing is a novel non-Turing paradigm of computation that uses interacting memory cells (memprocessors for short) to store and process information on the same physical platform. It was recently ...

As every CS undergraduate knows, the Turing machine is the usual theoretical basis for modeling computer program execution. The normal approach to the theory is to show that a correspondence exists ...

The DNA-based system is an experiment in how it may be possible to make a theoretical type of computer known as a non-deterministic universal Turing machine. Such a machine could solve tricky problems ...

If we go way back to the 18th century, we find ourselves in the heyday of mechanics. Indeed, many physicists believed that the world was essentially mechanical and deterministic. More importantly, ...
