non-deterministic polynomial time

The set of the most difficult problems in Mathematics, solvable in polynomial time only by a non-deterministic turing machine, but verifiable in polynomial time.

Also, why won't they publish "S4R" is a perfectly acceptable definition.

Rule number 5 + Rule number 10 guys. Seriously. I'm an editor too.
Aaron: Did you know the editors of UD don't actually follow rules 5 and 10?
Mike: Yeah, they turned down my definition for "np", y'know, its short for "Non-deterministic Polynomial time".

Aaron: Yeah, seriousy uncouth.
Mike: HOLLA!
