In the space of 5 minutes, bot_Hippo moved in both games vs bot_briareus. So it's not always thinking for 8 hours?

Ricardo, I have said it thinks for 8 hours single thread, but 5 copies of the bot are run in parallel. I would run 6 copies (on 8 core machine), but the memory consumption of the copy version is enormous so I am afraid of swap possibilities ... . I hope to debug the undo version early and it could solve the memory problems to allow 6 parallel runs.
When I last checked it the bot was gaining reserve as it was thinking in all 5 of its games where it was its turn.

The link in the menu still points to the 2012 postal tournament and not this years - http://arimaa.com/arimaa/tourn/postal/2012/showGames.cgi
No big deal, but I keep forgetting to click on the one in the middle of the page...

Thomastanck, the developer of bot_trash was last seen 2 months ago on Arimaa.com.
This is a game where bot_trash already timed out: http://arimaa.com/arimaa/gameroom/comments.cgi?gid=269572
You will probably win your game on time.

So my bot (bot_Hippo) as well as bot_trash finished their postal mixer games. My bot lost no game on time in contrary to the most games of bot_trash.
Unfortunately my bot won only one game on the board and was probably winning it's games against trash as well. I have converted my bot to do/undo rather to copying bitboards version during the mixer, but it had no notable influence on the search speed. I almost let the evaluation function unchanged. Trap controll understanding, mobility understanding (and forks) are the most obvious problems of it.... Very long way to make it play well.

Sadly for carbon-based intelligence, it looks like bot_briareus will eclipse its 10-4 showing from last year. So far briareus is 10-1 and the worst it is likely to finish is 13-5, which is counting on both browni3141 and me to win from positions that are currently materially even with no (bad for bot understanding) elephant deadlock. Only ChrisB and Alfons have dominating positions.
I continue to be amazed that briareus doesn't seem to suffer from the longer time controls in the way that most bots do. Even given the relative time handicap that human players aren't thinking as long per move as bots, most bots seem to slightly underperform their 2-minute-per-move rating when they play in the Postal Mixer. I wonder what briareus's secret is for ourperforming.
In any case, I offer my premature congratulations to Ricardo.

Thanks Fritz! I don't know what the difference is to other bots, if there's indeed a difference. bot_hippo seems to have better WHRP than gameroom rating as well?
Maybe next year marwin, sharp or quad will participate in the mixer as well (hint, hint, hint), it would certainly be interesting to get more data about this.
PS: BTW, bot_briareus is currently on vacation from the postal, due to my own vacation. It'll be back in around two days (leaving the computer on 24/7 seemed like a bad idea with so few games left, there would probably be big periods of inactivity).

Personally I would discard my timed-out game for the purpose of comparing records. I had a significant advantage when it ended and would most likely have won.
I find it strange to call DD for hr even, although it seems roughly so much of the time. The game has been kind of crazy and I've given up on winning quickly, but I think you can count on me winning eventually

13-5 as a worst case is now a lock. Now to see if it can make it 14-4, 15-3 or 16-2 (unlikely) !

Whew, I finally won in 80 moves, the longest game of the tournament so far. I remember when we thought 80-move games would become increasingly common, but instead they have become rarities. I shouldn't speak too soon though, as there are games yet to finish in the Postal Mixer.
With browni scoring a sexy win in a goal race, briareus stands at 13-4 with only Alfons's game yet to finish. There's another position I can't see through clearly, although on a superficial perusal it looks like briareus has staged a comeback over the last ten moves or so.

Even if there is another 80-move game, it may take months to reach that point still. The large initial reserve and a mutual willingness to use almost all of it have meant my last remaining game has seen only 27 moves played so far.

When I win the continued game that I timed-out against briareus do we modify that record, or would that be unfair?
