Title: Time Controls?
Post by maker on Nov 7^th, 2004, 11:07pm

Does anyone know what this two sentances mean?: Thus, when playing these qualifying games the program should be allowed to make full use of the time as it would in a real tournament game. Games played at this time control but with the program intentionally set to not make full use of the time will not count towards the qualifying games.
(from http://arimaa.com/arimaa/wcc/2005/rules.html)

Does this mean that we can not have time controls that stop our bots from sending back a 'best move' that they have generated but were still checking to see if it was indeed the best move? What if the idea behind the bot is to generate the best move found so far and to go as deep as possible? Are we supposed to statically delcare how deep we wish the bot to go? How can you statically do this and get the bot to perform well? Anyway, if the idea is that we can't just change the bot between games considered for the selection and the matches, why not just say that? Sorry for the slew of questions, but I was planning on regulating my bot based not on the quality of the move so much, but on the quality of the entire subtree generated from several 'good' moves. Thank you for your patience.

What you were planning is fine.

That clause is just designed to prevent "miniature versions" of the bots being used to qualify. Ones that hardly use any of their time to think about moves. They are supposed to show their full strength whilst qualifying.

bot_bomb is set to use slightly less than full time, so it can accumulate some reserve time. It will typically use between 90 and 120 seconds per move, but will sometimes go over 120 or less than 90.

When there is a forced goal, it returns it immediately, so at the end it will play very quickly.

I assume this is ok. Bomb will use the same time control settings in the tournament. Between then and now I might improve it to use reserve better in complex positions.

so it'd be ok if I just told it to not run over time?

Yes, that would be fine.
