Updates: Number of Legal 18×18 Go Positions Computed; Latest XKCD Go Comic

Tue, 17/03/2015 - 14:00

Number of Legal 18×18 Go Positions Computed; 19×19 On The Horizon: “It took about 50,000 CPU hours and 4PB of disk IO, but now we know the exact number of legal 18×18 Go positions,” johntromp wrote in a recent post on slashdot. “Seeking computing power for the ultimate 19×19 count,” the post continues. “Thanks to the Chinese Remainder Theorem, the work of computing L(19,19) can be split up into 9 jobs that each compute 64 bits of the 566-bit result. Allowing for some redundancy, we need from 10 to 13 servers, each with at least 8 cores, 512GB RAM, and ample disk space (10-15TB), running for about 5-9 months.”
Thanks to Steve Colburn for passing this along.

Latest XKCD Go Comic: In a possibly related development, here’s the latest go comic from xkcd, “A webcomic of romance, sarcasm, math, and language.”

The Power Report: China Beats Japan in Agon-Kiriyama Play-off

Tue, 17/03/2015 - 00:23

John Power, Japan Correspondent

China Beats Japan in Agon-Kiriyama Play-off: The 16th Agon Kiriyama Cup Japan-China Play-off was held at the Kyoto headquarters of the Agon sect of Buddhism on March 14. Representing China, the 17-year old Ke Jie (right), winner of the Chinese version of this title, beat Iyama Yuta of Japan, so China won this title for the 12th time in a row. Holding white, Ke secured a resignation after 146 moves. Iyama seems to be in the worst slump of his career. Besides this defeat, he lost the two title matches he played at the end of last year and he has just lost three games in a row in the Kisei title match. The seventh Kisei game is going to be extremely important for him.
