I am very surprised to hear this.

• Eric Veach は Google で AdWords 開発を率いていた!
  (Eric Veach had led the AdWords team of Google)

Needless to say, Eric Veach is a guru of GI researcher.
I have wondered where he vanished after his great doctor thesis.
And now I know he was at Google, and used his speciality of probability statistics for the AdWords.

I've been believing that GI problem has very rich context.
It can be used as the best tool to think algorithms.
