[ExI] alpha zero

[Dylan Distasio]

The paper describes in detail how they did it and how long it took.  Again,
I see no reason to question any of it.  It's an evolutionary advance from
their work on Go, and is using established deep learning and reinforcement
techniques on powerful hardware (although not insanely powerful, 4 TPUs is
not unobtainium

).
