AlphaGo-AlphaGo Game 10 (Part 2): An unexpected trade and a 10-group battle

Saturday October 7, 2017

Part 2 of the Game 10 commentary begins at move 113. “At this point, the game looked ready for a peaceful endgame, with White in the lead.”2017.10.07_AlphaGo vs. Alphago Game 10-part2 2017.10.07_ag-ag-thumb-10bsays Michael Redmond 9p in his commentary. “By move 121, however, White has given away about 20 points, an unexpected trade that transforms the game radically. Back in a wildly dangerous middle game, complications that arise from a fight in the center will put ten groups in danger.”

“Looking forward to these every week,” Leo Dorst commented on Part 1, echoing the sentiments of many viewers. “Such a great way to start the weekend after a late Friday night at the Amsterdam Go Club. Rereading my old Go World magazines I see Michael moving to Japan. If he had not done so and trained there, we might not now have these wonderful commentaries. Sometimes the world just makes sense…” Watch for a Q&A video here next week with Redmond in which he responds to selected comments.

AlphaGo-AlphaGo Game 8: Two 3-3 invasions and some spectacular fighting

Friday September 22, 2017

“In this game we’re going to see two 3-3 invasions; when AlphaGo jumps in to the 3-3, the other AlphaGo does as well,” says Michael Redmond 9p in his game commentary on AlphaGo-AlphaGo Game 8. “This is something that happens a lot, and I have my own theories about why that might be. We’re also going to see the follow-up moves in both of those corners, so we’ll see some options about possible follow-ups. And then there’s going to be some spectacular fighting inside of Black’s moyo. “2017.09.22_ag-ag-thumb-8

Your Move/Readers Write: AlphaGo is unbeatable; get over it

Sunday September 10, 2017

“Apparently, some people believe that someday a human will be able to defeat AlphaGo,” writes Joel Sanet. “It’s not gonna happen. The reason is biological, not technological. No human being is capable of thinking about the game the way AlphaGo does. AlphaGo’s way of thinking is better than the human way; ergo it is no longer possible for a human to beat AlphaGo. We human beings are not capable of considering a choice of moves by determining a concrete number for each called “the probability of winning” then choosing the one with the highest value, but this is what AlphaGo does.

“Thinking that it is possible for a human to win now is due to anthropomorphization, the application of human attributes to something that is not human, a process rampant in the go community. I have heard people say, ‘AlphaGo likes the early 3-3 invasion’ or ‘He (or she) likes thickness.’ AlphaGo can’t ‘like’ anything because it has no emotions. It plays the early 3-3 invasion because it maximizes its probability of winning in certain openings. Also, as far as I know, AlphaGo has no concept of thickness. It has nothing to do with how AlphaGo derives its moves. Furthermore, AlphaGo is not a ‘he’ or a ‘she’. AlphaGo is an ‘it’.

To attribute thinking to AlphaGo is also a mistake. I wrote that it chooses the option with the highest probability of winning. It doesn’t “choose” anything because it isn’t self-aware. AlphaGo receives input, does what it is programmed to do, and produces output. To me this is more akin to a human knee jerk than to true thought. A doctor’s percussion hammer causes sensory neurons to fire off a signal to the spinal cord where it is processed and returned to the knee via motor neurons without intercession of the brain. This is analogous to AlphaGo’s input-programming-output. AlphaGo’s programming is immutable. The day AlphaGo changes its own programming is the day I’ll say it thinks.

Nevertheless, humans can learn from AlphaGo. We have learned that the shoulder hit is a lot more useful than anyone thought. AlphaGo’s new 3-3 invasion joseki makes sense so we can benefit from that, but I advise you not to do the early invasions until you are able to read the rest of the game to the end.

Alphago’s supremacy over humans is no reason to feel that studying go is a dead end. Your study is de facto open-ended because you will never reach the end of it. People study go to improve, not to become the strongest player on the planet.”

AlphaGo vs AlphaGo Game 6: Flexibility and a bias for complications

Sunday September 10, 2017

“In this game AlphaGo shows its flexibility when Black abandons a running fight and tries to control the open lower side of the board instead,”2017-09-10-alphago-game-5-video says Michael Redmond 9p in his game commentary on AlphaGo-AlphaGo Game 6. “In the second fight of the game, White deals with two weak groups masterfully. Finally, Alphago shows its bias for complications when White allows a dangerous ko in the corner.”

DeepZenGo wins all-AI go competition

Wednesday September 6, 2017

At an all-AI go competition held in China, Japan’s DeepZenGo took first place and then bested top Chinese pro Kong Jie 9p, who was being assisted by one of the AI runners up, CGI, from Taiwan. Jie was able to choose which AI to use as an assistant, and opted for CGI over the Chinese system FineArt, which had come into the tournament as a favorite. Among the 12 contestant systems, one North American entrant, MuGo by Brian Lee, came in 11th. MuGo was only six or so months old, and not that strong yet, but Lee was pleased to play against other systems, and preparing for this event with a short lead time was good motivation to work harder. “It was good to have a goal. I’d been working on it alone for four months, and it’s difficult to construct imaginary castles when there’s no one looking at it but yourself.” Scheduling conflicts kept other North American Go programmers, like Dave Fotland, away and Facebook has not been working on its system actively. The AlphaGo group did not attend, with the final versions of AlphaGo having retired from competition after the match with Ke Jie 9p in May. The competition took place in Ordos City, China, at the first ever Chinese Go Congress, a well-attended event that brought together 5,000 mostly amateur attendees, according to organizers.
