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. In mathematics and computer science is shortened to np. Of course, the editors of UD would rather publish BULLSHIT or several thousand entries for George Bush than something having to do with math. 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".
James: Yeah, and then the go and publish shit like "S.C.L.I.D". Apparently technical terms for guns are fine, but not in Math.
Aaron: Yeah, seriousy uncouth.
Mike: HOLLA!
Fogey/fogy /fougi/ sl. (early 18C+, orig. Scot) old-fashioned, stuck-in-the mud.
Person with old fashioned ideas which he is unwilling to change: Come to the disco and stop being such an old fogey!
You think me an old fogeyand an old tory, his thoughtful voice said. I saw three generations since O’Connel’s time. I remember the famine. Do you know that the orange lodges agitated for repeal of the union twenty years before O’Connel did or before the prelates of your communion denounced him as a demagogue? You fenians forget some things. (James Joyce, Ulysses. Penguin Books,1992. p. 38)
