Yes, I mean shogi computer programs like bonanza, elmo, gnushogi, etc. What is the preferred opening game of the strongest Shogi computer
programs like dolphin or elmo, without using a human-directed opening book, but with the games purely improvising their playing? Also, what is
the favored castle structure of the most powerful shogi programs, like dolphin or elmo? of course, the best castles to use depend on the position of the
game. yokofudori seems to be a popular opening game for the most powerful computer players, but sometimes it seems that the most powerful shogi
computer programs play opening games and use castles that are not conventional among human players. Answering this question might give some
clues about what is the most "optimal" shogi opening game or castle structure. Of course, given the huge game tree of Shogi, even the strongest current computer
players may be playing much less than is optimally possible, so maybe no firm conclusion can be drawn about what is the best opening game or castle
structure from the most powerful current shogi programs.
