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. They indicate that the problem of solving a level in "Super Mario Brothers" is as hard as the hardest problems in the "complexity lesson" PSPACE,meaning that it's even more complex than the traveling-salesman problem, or the problem of factoring large numbers, or any of the other hard problems belonging to the better-known complexity lesson NP.
