5 games have been played between a new go program called Alphago (from google deepmind) against the top European champion. No handicap stone. The program won the 5 games.

Games can be downloaded at http://www.usgo.org/news/2016/01/alphag ... i-advance/.
In March it is said that Lee Sedol (regarded as the strongest go player in the world by many) will play Alphago.
What's next?
Go has fallen to computer domination?

Re: Go has fallen to computer domination?
It's a great achievement for computer go, but the difference between top European players and top Asians is probably like a difference between an IM and a GM. The best Polish player, Mateusz Surma, who has gained the newly created title of "Europaean professional" recently (there are only 4 or 6 of them) was far from the best in the Korean go school.
This being said, I looked at the game and its flow was surprisingly natural.

Re: Go has fallen to computer domination?
It is very important to note that Alphago is a knowledge-based system: in contrast to IBM's Deep Blue, Google have used deep neural networks.
Firstly, they learned from a database of existing games, then the system played millions of games against itself, steadily improving.
Human level intelligence is quickly coming into sight...

Writing is the antidote to confusion.
It's not "how smart you are", it's "how are you smart".
Your brain doesn't work the way you want, so train it!

Re: Go has fallen to computer domination?
Fan Hui is 2p professional. 5-0 suggests at least 4p for AlphaGo. Also, it beats normal MC programs like Crazy Stone (say 5 dan on i7) by 99.8%, which suggests 8-10 more stones, also above 4p. This thing runs on 170 GPU cards and 1,200 standard processors, and assuming quadrupling for a stone, it has 5 stones advantage over normal hardware on KGS (say a cluster of 24 regular cores). Lee Sedol is above regular 9p. Let's see.

Functional programming combines the flexibility and power of abstract mathematics with the intuitive clarity of abstract mathematics.

Yes, that's amazing.Bloodbane wrote:This was the most shocking part in my opinion.Laskos wrote:Also, it beats normal MC programs like Crazy Stone (say 5 dan on i7) by 99.8%, which suggests 8-10 more stones, also above 4p.
I have a better estimate, using this site: http://senseis.xmp.net/?EGFRatingSystem . 99.8% against 6d Crazy Stone seems close to 500 ELO points (or whatever it's called). It means close to 5 stones. If 1p is ~ 8d , then 5 stones above Crazy Stone is about 4p. It seems to me AlphaGo will lose to Lee Sedol (9p).

Re: Go has fallen to computer domination?
IIRC professional go grades are not one handicap stone apart. More like 1/3 of a stone.

Re: Go has fallen to computer domination?
Thanks, I think that's correct. Then if AlphaGo is 5 stones above Crazy Stone, it should be close to 7-8p.PK wrote:IIRC professional go grades are not one handicap stone apart. More like 1/3 of a stone.
Wonder how much of this 5 stone advantage is due to those 170 GPU cards.
