2010 Challenge Screening

I'm going to start a thread specific to the screening, partly so we can dissect the game results and discuss any technical issues that arise, and partly so that I will be able to extend the following table and find it next year:
Year Pairs Decisive Winner/Score Loser/Score
---- ----- -------- ------------ -----------
2007 12 . 2 . Bomb / 2 Zombie / 0
2008 16 . 7 . Bomb / 6 Sharp / 1
2009 23 . 7 Clueless / 5 GnoBot / 2

I just now tried to play a screening game, and I get the message

However, bot_clueless vs. Hippo is the only screening game at present. The other server should be available. What's up with that?

I got the same message and after I pointed this out to Omar, he fixed it for me.

In honor of marwin's winning the first decisive pair of games of the 2010 screening, I have updated the table to add a row for this year. Also I have included performance ratings for each bot for each year over all screening games played (i.e. not just over the paired games)
Year Pairs Decisive Winner / Score / Perf Loser / Score / Perf
---- ----- -------- --------------------- --------------------
2007 12 . 2 . bomb / 2 / 2087 . Zombie / 0 / 1876
2008 16 . 7 . bomb / 6 / 1918 . sharp / 1 / 1576
2009 23 . 7 clueless / 5 / 1910 . GnoBot / 2 / 1792
2010 25 . 11 marwin / 6 / 2065 clueless / 5 / 1960
The performance rating is perhaps not very reliable. Bomb in 2008 and clueless in 2009 had similar performance ratings from the screening, but bomb went 0-9 in the Challenge whereas clueless went 2-7. We shouldn't read too much into marwin's impressive 4-3 start in the screening.
[EDIT]
updated through game 139910 (including joe's game 138003; not including hanzack's games or quad's)

Without going into a lot of detail, I'm going to use a gut reaction and allow joe to replay the game against bot_marwin that he resigned by mistake on move 3. I'm not sure about the precedent this sets, but it seems like human confusion was the root cause. If this were a WC game I would rule that the result must stand, but the screening games are all about getting information about bots' playing ability against humans. Forcing this result to stand would be counter to that purpose.

In my week-long absence the race tightened up. Marwin now leads only 3-2 in decisive pairs, and has an unpaired loss to novacat. The screen, like the Computer Championship, could go down to the wire.
I have updated the table in my previous post. The screening performance ratings of marwin and clueless are now 2036 and 1977 respectively, rather in line with my gut feeling about their true abilities under Challenge conditions.

Wow, clueless's win over novacat brings the match all square, 3-3 in the six decisive pairs. This is as exciting as the Computer Championship itself! I hope we have several more pairs completed before the month is over, starting with onigawara, 722caasi, camelback, Simon, The_Jeh, joe, and clauchau finishing the pairs they started. Marwin's performance rating in my table is still slightly higher than clueless's because of incomplete pairs slightly favoring marwin overall.

I'm not going to play at 2 min control anymore. It was tempting to play new bots but annoying to get dragged beyond 4 hours. At last I had to leave while in winning position and can't unrate.
May be there should be different time control options in the future for bot screening.

At one point I was in favor of different time controls, but I changed my mind. The screening time controls should be the same as the challenge time controls, and those should not change.
I like that Omar hasn't changed the rules of the Arimaa Challenge for several years now, including the time controls. People who try to meet AI challenges always have to face the "moving goalposts" syndrome, i.e. whenever they get close to humans, the match conditions change to make it more favorable to humans. I was upset when Omar changed the Arimaa Challenge to require beating three out of three defenders, since that is harder than just beating one defender. By the same token I don't want to have faster time controls now when humans don't mind and then change to slower time controls later when we need it. It's not fair to base the match conditions on what is most convenient for humans at the moment.
Besides, it turns out that we are having an awesome screening at two minutes per move. Since I last wrote, The_Jeh and onigawara completed pairs, moving the score to 4-4, still tied! I somehow feel we won't know until the very last day which bot will advance.

Thanks Nombril. I hope I get some more free nights to take revenge on marwin.

How exciting! Rabbits' punchout of marwin gave clueless the lead for all of 83 minutes before Eltripas downed clueless to even the score at 5-5 again. Just two and a half days left in this thriller...

I have plans to try a reckless race game against marwin again, after almost winning (is there such a thing in arimaa?  ) last time. I just need to find time so I can play both bots before the deadline.
I watched marwin's defeat to rabbits yesterday. Talk about putting up a death struggle at the end!
Cheers,
knarl.

Heheh. Your game against marwin reminds me of something I once heard a chess player say: "He creamed me, but just barely!"
