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 ...

Completing a game of "Super Mario Brothers" can be hard -- very, very hard. That's the conclusion of a new paper from researchers at MIT, the University of Ottawa, and Bard College at Simon's Rock.

Back in January we looked at the work of Giovanni Viglietta at the University if Pisa in Italy who had proved the computational complexity of many computer games from the 80s and 90s, such as Pac-Man ...
