[Computer-go] Congratulations to CrazyStone!

[Nick Wedd]

Congratulations to CrazyStone, winner of yesterday's 20-round 9x9 KGS bot
tournament, with one loss, two jigoes, and 17 wins.

My report at http://www.weddslist.com/kgs/past/116/index.html is longer
than usual, so is likely to contain mistakes. If you have any comments on
it, I hope you will let me know.

I don't agree to that assessment. Black had three more threads on the upper 
right corner (f9, j9, h9) if he needs to, so there was no way White could have 
won the game. Of course Sa6 was also a thread removing thread, but it didn't 
mattered anymore since white removed threads first (so they both agreed more or 
less to finish the Ko early).

I think you are right. I had missed the threats in the upper right. I will
delete that section.

[computer-go] Congratulations to CrazyStone and to StoneCrazy!

[Nick Wedd]

CrazyStone and StoneCrazy were the winners of the two divisions of 
yesterday's bot tournament.  Both were undefeated.


My report is at http://www.weddslist.com/kgs/past/40/index.html.  It is 
quite short, but this in no way reflects on the participants.  The 
standard of play was particularly high.


I would, as usual, appreciate it if readers would report mistakes. David 
Fotland and Jason House, in particular, may have corrections to make.

Re: [computer-go] Congratulations to CrazyStone and to StoneCrazy!

[Michael Williams]

Here's a quote from Formal Division, game 2:

--QUOTE---
   When the players were asked by the server to submit their lists of dead stones, ManyFaces submitted a (correct) list, and HouseBot submitted no list 
(HouseBot never submits a list). What ought to happen when one player submits a list and the other does not, is that the server believes the list it does 
receive, and scores the game accordingly; and at one time, this was what did happen. Thus HouseBot's failure to submit a list is trusting (it leaves itself open 
to being swindled by an unscrupulous opponent) but legal.
   However, for some months now, the server has been behaving incorrectly. When only one player has submitted a list of dead stones, it acts as if the 
other player has claimed all its stones were alive (Jason House had reported this bug to me, but I had failed to read his email properly, and did not act on it. 
I have now reported it to wms, the programmer of KGS, and he has acknowledged that it should be fixed). This causes play to resume, until the status of all the 
disputed stones has been established. So in this game, play was resumed, but HouseBot, which had only 30 seconds left, timed out without moving, and thereby 
lost. David Fotland then generously asked me to treat the game as a win for HouseBot, which I did. The game is shown as forfeited by ManyFaces1, not the 
designation I would like, but I have no power to change it.

---END QUOTE--

I wouldn't consider that a bug.  It seems correct as is.  If the behavior is changed, it would be in engine developers best interests to always submit a list 
that has all friendly stones alive and all opponent stones dead.  This is easy to do and guarantees a win against bots like HouseBot that don't return a list. 
It would essentially make not submitting a list illegal.  But there is no reason to make that illegal (or effectively illegal) since bots don't care if they 
have to play the game out completely.

ManyFaces1 (formal) is the new UCT player.  ManyFaces2 (open) is the
alpha-beta searcher.  The alpha-beta engine did much better than I expected.

ManyFaces1 was running on one CPU of a 2.33 GHz core2 Duo.  ManyFaces2 was
on one CPU of a 2.0 GHz Core2 Duo.
