A paper describing the deep learning dual neural network used for this feat can be found here https://storage.googleapis.com/deepmind ... ing-go.pdf

In the paper they say that the level of play achieved so far was previously thought to be still a decade away. If true, AlphaGO is a monumental achievement.

Note that Facebook has a rival program. Now that Zuckerberg learned Mandarin, he is aiming big at China, lol

It is. 494/495 score was achieved at 5s/move (not ultra-fast) single machine. Against Lee Sedol the distributed version will play. Humans are in a serious trouble.

The rival of facebook is google whose bot can be found in the link you provided. If you meant to say that Google Deepmind has a rival with facebook (and their darkforest bot), it's not really true. Facebook bot still hasn't reached zen's level (zen is 6 dan on kgs, darkforest only 5 dan) which is much, much weaker than Alphago (around 800 to 1000 elo weaker).

In fact from the 4 stone handicap games listed here http://www.computer-go.info/h-c/ and knowing that single machine AlphaGo beats consistently at 4 stone handicap both Crazy Stone and Zen, it seems the distributed version is even above normal 9p. Sedol is not a normal 9p, though. The estimates in the original PDF paper seem conservative to me. Also, they are using some own rating based on BayesElo with a constant Delta, which are hard to translate to EGF GoR.

I think people that probably uses thread view, tend to lose posts that they are never read, like the mine posting exactly the same link of BBC:-)

Here are some comments from top Chinese players:

1. Ke Jie (world champ) – limited strength…but still amazing… Less than 5% chance against Lee Sedol now. But as it can go stronger, who knows its future…
2. Mi Yuting (world champ) – appears to be a ‘chong-duan-shao-nian (kids on the path to pros)’, ~high-level amateur.
3, Li Jie (former national team player) – appears to be pro-level. one of the games is almost perfect (for AlphaGo)

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?
Videos available on DeepMind site:

can the software be converted to chess use and do you think it will be comparable to stockfish/komodo?

I know the incentive isn't there because "we've already beaten the World Human Champion", but do you think a project like this could work for chess?
