"Rogue Algorithm" -- a cinch for idiom of the year lists.

I would have thought "rogue algorithm" might have been used in
reports about the 2010 crash (I certainly thought of it as such), but
Google News doesn't show it. So it may not be the retro idiom of the
GNews does, however, claim a couple of instances before 12/31/2011,
in 2007 (a Skype crash) and 2009 (a Reuters article speculating about
the possibility, just 10 months before the 2010 actuality).
And used in computer contexts earlier -- 2002 re XML security, 2006
re generating dungeons. GBooks. Nothing earlier there for the exact
phrase, but an unverifiable snippet from "Doctor Dobb's Journal",
allegedly 1997, for "rogue * algorithm".
Not the most thorough searching; others will surely do better.
