Computer Beat Shogi Pro
http://unlimitedgo.blogspot.com/2010/10/computer-beat-shogi-pro.html
It's not a big deal for a chess software to beat top player in an even match
, but the story is different in shogi, since it has more possibility than
chess (the ability to drop pieces in shogi makes it more complex than chess).
A computer has taken down top women's shogi player Ichiyo Shimizu in a
special game staged at the University of Tokyo, moving development of
software for the Japanese chess game a step ahead.
Ichiyo Shimizu
The game lasted six hours and three minutes. Shimizu, a professional shogi,
or Japanese chess, player, has won titles at 45 competitions, the most of
any female player.
The shogi system, titled "Akara 2010," defeated Shimizu, holder of the women
's Osho title, in 86 moves.
"It made no eccentric moves, and from partway through it felt like I was
playing against a human. I'm a bit frustrated by the loss, but I gained
respect for the people who took part in developing the software," Shimizu
said. "I hope humans and computers will become stronger in the future
through friendly competition."
"Akara," after which the shogi system was named, is a Buddhist term meaning
"10 to the power of 224," a figure close to the total possible number of
unique shogi games. The system combines four shogi software programs --
Gekisashi, GPS Shogi, YSS and Bonanza -- and selects the best move through a
majority.
In the game with Shimizu, each side had three hours. Akara 2010 played with
a "ranging rook" strategy, offering an exchange of bishops. Shimizu made a
questionable move partway though the game, and Akara went on to win.
The game was staged after the Information Processing Society of Japan
approached the Japan Shogi Association and suggested holding the match.
Society member Hitoshi Matsubara, a professor at Future University Hakodate,
said the computer's win came after decades of work.
"I started developing shogi software 35 years ago, and for the software to
become this strong is enough for me to forget all the hard work."
In 2005, the Japan Shogi Association introduced a ban on professional
members playing shogi computers without permission. The latest game was the
first human versus computer game approved by the association since Ryuo
champion Akira Watanabe defeated Bonanza in 2007.
Will future go software will also able to beat human in an even game? If yes
, how far that future is? Only time will tell.
