I just looked at 133684. ego110_allfirst took all the way until move 18 to play a move above the 2nd line. In fact, in the 8 moves it made prior to that, 5 were on the first line. ErlyGo's random plays had only 2 on the 2st line and 2 on the 2nd line. It seems like a random strategy gives a better opening strategy than what ego110_allfirst ends up with.
I've been wondering what was done to ego110 to make ego110_allfirst, but have been unable to find out yet. There's been lots of discussion lately on what would make a good "all moves as first" bot with no final conclusions. I know that my AMAF variant shares more in common with ego than Don's, and Don's version. My bot is better than ego and Don's is better than mine. I've been toying around with time control lately (and failing to get it right). I can take down housebot-xxx-ucb and put up housebot-xxx-amaf if that helps with testing of erlygo. (housebot-xxx-shuff is needed for my timing test since it seems to stress the time usage policy more than my other variants) On 9/24/07, Don Dailey <[EMAIL PROTECTED]> wrote: > > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Did you look at the games? > > I looked at game 133580.sgf and your program was clearly lost playing > the black pieces, however the game record says that your opponent > resigned in a dead won position. > > In fact, there were not moves left to play other than filling eyes. > > > - - Don > > > > Urban Hafner wrote: > > Hej all, > > > > I'm wondering if anybody knows how ego110_allfirst on CGOS works.
