Re: [gnugo-devel] Patches for 3.8

[Daniel Bump]

A Jacqueline Go that seems vastly stronger than the last time challenged GNU
Go again in the Computer Go ladder, and this time Jacqueline won.

A second game was played with GNU Go's --monte-carlo option, and again
Jacqueline won. The small margin is misleading -- UCT players such as
Jacqueline (and gnugo --monte-carlo) tend to give up points when they
are ahead.

Here are the game records.

jacqueline [?\]: in the beginnig it looked so bad

jacqueline [?\]: I don't know
jacqueline [?\]: I can't beet Jacqueline Go any more
jacqueline [?\]: Gnu Go neither
dwbump [?\]: b8 is a good move
jacqueline [?\]: what level played gnu go?
dwbump [?\]: Level 12. Gunnar thinks we should have used the Monte Carlo option
dwbump [?\]: which may be stronger
jacqueline [?\]: probably yes
jacqueline [?\]: Jg is a UCT programm
gunnar [?\]: Can't B8 just be answered at A8?
dwbump [?\]: yes, i guess so.
jacqueline [?\]: Jg plays G4 on A8
dwbump [?\]: would jacqueline like to try a game against gnugo's monte carlo 
mode?
dwbump [?\]: i can start that up
jacqueline [?\]: ok
dwbump [?\]: I restarted DeepGNU with --montecarlo
dwbump [?\]: if you make a challenge we can see
dwbump [?\]: (not a ladder game)
jacqueline [?\]: can we switch colors?
dwbump [?\]: I think you can do that from the challenge window
dwbump [?\]: am i right?
jacqueline [?\]: probably, but I cant find that option
dwbump [?\]: does anybody know how?
dwbump [?\]: looks like there is another match
