AlphaGo Zero-AlphaGo Master: Two openings, less variety

Saturday November 11, 2017

“In the set of 20 games between AG Zero and AG Master, there are pretty much just two openings — i.e. identical moves for about the first 202017.11.11_ag-ag-zero-opening moves — one with Zero as Black and one with Master as Black,” says Michael Redmond 9p in this first commentary on the recently released AG Zero games. “This provides an opportunity to examine how Zero differs from Master, as well as how Master differs from earlier versions. ”

“When AGMaster plays against AGZero, it does not show the variety that it had before,” says Redmond. “As AG does not change within a version, I find it hard to accept that it apparently does not have the option to play moves that it played before in identical board positions. In the ‘Master series’, 60 games played against top pros in Dec 2016 to Jan 2017, Master could play the 3-4 point as it’s first move in about 1/4 of the games when it had Black. Incidentally, AGKeJie also could play the 3-4 point in some of it’s games. The fact that Master repeats the same opening every time in these games against AGZero bothers me and makes me question, is this truly the same version of AGMaster that played the Master series, and if so, what caused it to play the same opening every time in this series, when it was allowed to have variety in previous games with identical board positions? The difference in calculated winning percentage between A and B should be extremely small and I would expect it to have little or no effect on the ultimate win-loss record. This set of games would be much more valuable if Master had been allowed to vary in it’s choices for moves.”

AlphaGo-AlphaGo Game 15: New, different and possibly bad

Friday November 10, 2017

“I don’t like to call it weird, but in this game we’re going to see some new and different stuff that AlphaGo is doing with the joseki that I don’t 2017.11.10_ag-ag-thumb-15really understand and I don’t like it,” says Michael Redmond 9p in his commentary on Game 15. “It’ll be interesting to see if eventually I change my mind, but for now I’m going to say it’s a bad move.” Redmond adds that “We’ll also see another typical AlphaGo move later in the game that’s pretty exciting too.”

Redmond announces new series on AlphaGo Master vs AG Zero

Saturday November 4, 2017

“We were expecting DeepMind to make some sort of an announcement (about a new version of AlphaGo),” says Michael Redmond 9p, “But 802017.11.04_agzupdatethumb games was a big present.” (Self-taught AlphaGo Zero bests all previous versions in record time Redmond discusses AlphaGo Zero with the E-Journal’s Chris Garlock in a brief video announcing the launch of a new series of game commentaries. DeepMind released four sets of games for the self-taught AI, including training games, games against the Fan Hui version, the Lee Sedol version and the Master version, which defeated 60 top human opponents earlier this year. “I’m going to be looking at the games where Master plays Zero, mainly because Master is such a popular version of AlphaGo,” Redmond says. Master’s tactics, including big shimaris and emphasizing the center “people wanted to play, but were afraid because that way of playing is weak in territory. Master showed us some successful ways…and is still having an effect on how professionals play. So it’s going to be really interesting to see Master playing against a stronger version of AlphaGo.”

AlphaGo-AlphaGo Game 14: A double kakari and a new joseki

Saturday November 4, 2017

“In this game we’re going to see a double kakari against a star point, a first for this series of games,” says Michael Redmond 9p in his game 2017.11.03_AG-14commentary on Game 14. “In the Master vs. human series back in January, Master would play away when the opponent played a kakari against a star point, sometimes. Now we’ll get to see how Master plays this with White, and it has a special move. Its a new joseki that actually make s some sense, so it’s going to be interesting.”

Sunday October 29, 2017

“This is a very different game, in that there are three corner enclosures,” says Michael Redmond 9p in his game commentary on AlphaGo-2017.10.27_AG-13AlphaGo Game 13. “Black isn’t playing a kakari, which is different from what human players do now.

AlphaGo-AlphaGo Game 11: A calmer game, with hidden reading

Friday October 13, 2017

“This game is a lot calmer than Game 10,” says Michael Redmond 9p in his game commentary on AlphaGo-AlphaGo Game 11. “There’s a lot of 2017.10.13_ag-ag-thumb-11fighting that doesn’t actually come into the game, but I’ll be showing a lot of variations about things that could have happened, so there’s a lot of, you might say, hidden reading. And then there’s a ko at the end, for the life of a group. ”

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.

Sometimes the world just makes sense…” Watch for a Q&A video here next week with Redmond in which he responds to selected comments.
