Oops, copied the wrong link. Fixed it now. Also fixed on the WCC rules page. Thanks.

What about the disabling of over-1500-rated server bots during event games? Will that be in force for the WCC, or only in event games when one of the players is human? My memory of what a hassle it was to have server problems during one past WCC leads me to suggest not taking any chances with overload, even if it means server bots being disabled for half of the day all week long. I will see if I make bot_ArimaanatorFast available during some of that time.

Do we have some place to see the CC2011 results and schedule? I've heard about the result (marwin-clueless) in chatroom, but search for results/games was not successful.

I contacted the TD today regarding a timeout we had in the bot_clueless vs bot_marwin game.
Quote:
Hi Ned,
The bot_clueless vs bot_marwin game ended with clueless losing on time. It was
also losing on the board so it did not have an adverse effect. An investigation
of the problem found nothing wrong with network. However the gold.arimaa.com
server seemed to be running very slow. An investigation of that found that
clueless itself had hogged too much memory and operating system did not have
enough memory for swapping and began using the disk which usually causes it to
run much slower. So the fault was of clueless and not the server. To prevent
this from happening in future games, Jeff Bacher would like to change the
setting for clueless to use a smaller hash table. He has asked me if I can make
the change. The rules state:
Once the programs have been submitted for the tournament, they may not be
modified manually, but can modify themselves if it can be done as an automated
process.
So I would like to get your decision on this matter.

Omar,
I'm going to let jdb make this change.
This was a really hard decision. I want to have the intended version of Clueless compete, but the letter of the rule does not allow it. So I compared this situation to others, in my imagination, where a control parameter, like maxSearchDepth, was set wrong at submission. I would not let a programmer change the move selection algorithm, but where does the algorithm end and adaptation to the run-time environment begin? Well, I decided there is a boundary. I'm having trouble quantifying it, but I'm going to use intuition and decide that hash table size is adaptation to run-time environment, which I'm going to allow for everybody on a case-by-case basis.
I realize that one can make the case that managing run-time environment resources is part of AI. That's not the part of AI I'm interested in. I'm also worried about somebody intentionally planning to adapt a parameter in their bot based on it's play in early rounds. I would not like to allow that. The difference is it being intentional.

I edited the clueless.cfg file to set:
number_of_hash_table_entries = 10000000
Previously it was set to 30000000.

That's how I would feel about it. There is a meaningful distinction between the engine per se and its manifestation on a particular piece of hardware.

So just as a note of curiosity there are actually two equally valid pairings for round two. The pairing actual chosen by the current pairing program is:
Marwin - Briareus
Sharp - Bomb
Opfor - Clueless
There is also an alternate pairing that carries the same weight:
Sharp - Marwin
Opfor - Briareus
Clueless - Bomb

If I understand correctly, the final CC game will take place today at 5pm CET, so I'm available to comment, and Karl as well apparently.
I think it would be great if people from the bot community could jump in the studio whenever they want during the commentary, to tell us about their own bot, how aggressively they prune / how far they search / what tricks they use / etc, about sharp and marwin, what kind of positions are better suited to one or the other, about how to interpret things like bots playing fast / slowly on particular moves, how their own bot or hope copies evaluate the position / the move(s) they suggest, and so on. So guys, please bring your mics along!

Thanks!
I've *just* finished exams, yay. That concludes the single busiest semester in my undergrad education (and the only semester in which I've had to pull multiple all-nighters).
I don't know if it will get posted online by Harvard somewhere, but if not, then at some point in the next week or so, I'll fix a few typos and some errors that I noticed and post it up myself.

Wow, that's an achievement.
I'd also like to read your thesis once it's available.
