That was my main thought, on reading the Kasparov interview, too. I'd include MCTS under tree search. Most interesting AI problems cannot be phrased in a way that all the wonderfully clever ways we have for searching 2-player trees can be used. The really clever bit of both Deep Blue and AlphaGo, was taking an order of magnitude more computing power than what had gone before, and actually getting it to work.

The other thing that struck me: Deep Blue has been regarded as "brute-force" (often in a derogatory sense) all these years, dumb algorithms that were just hardware-accelerated. But I remember an interview with Hsu (which sadly I cannot find a link to) where he was saying that Deep Blue contained most of the sophisticated chess knowledge and algorithms of the day: it wasn't just alpha-beta in there. So seeing Deep Blue described as "chess algorithms" rather than as "brute-force" was interesting. Darren P.S. I feel I didn't quote enough of the interview - do try and find it. E.g. Saying how he didn't realize how badly Deep Blue had played until he analyzed the games with modern chess computers. That is an amazing thing to hear from the mouth of Kasparov! The book he is plugging is here - I just skimmed the reviews, and it actually sounds rather good: https://www.amazon.co.uk/Deep-Thinking-Machine-Intelligence-Creativity/dp/1473653517 -- Darren Cook, Software Researcher/Developer My New Book: Practical Machine Learning with H2O: http://shop.oreilly.com/product/0636920053170.do _______________________________________________ Computer-go mailing list Computer-go@computer-go.org http://computer-go.org/mailman/listinfo/computer-go
