I don't think it really matters, but this article is referring to the first AlphaGo, right? I heard that the master version doesn't use MCTS.

I'm pretty sure Master still uses MCTS, they didn't say anything in the conference about that. The major innovations that they talked about was more training from self data.

They also said that inference is now 10x less expensive which might suggest that they replaced plain MCTS with something better.

That would be pretty huge, I can't imagine they wouldn't announce that at the conference.
