Same code on weaker hardware than the one in the postal.
I'll probably start making small changes soon though.

Thanks for the clarification, and thanks for putting up a 30s/move bot so it isn't straight blitz against developer bots.  Good luck with the tweaking!

Is ziltoid running on a calculator? It amazes me how much of a difference there seems to be between ziltoid and briareus! I guess I don't have a good impression of briareus strength because I don't play it often and I am rapidly improving. Also, I might be trying to compare postal briareus with 30s ziltoid, which is obviously going to give me shady impressions of their difference in strength. It makes me wonder what a bot could do running on a supercomputer. I kind of doubt it could beat the best humans consistently, but it would be an interesting (although probably impractical) experiment.

It's running on a computer that's about 4 times slower than the one used for the postal tournament. Between that and 30s per move instead of 4 hours, we're talking about a factor of 1920 in thinking power, that is enough to go 1-2 plies deeper depending on the position. So I'm not surprised that you see a big difference in the move quality.

The biggest computer my bot has run on had 64 cores, it was pretty fast but doesn't count as a super-computer.
I have a version that can run on clusters but it didn't work very well on the Amazon EC2 cluster when I tried it some time ago due to high communication latency between the servers. In the meantime they claimed to have fixed a bug that was preventing users from choosing machines that are very closely located, maybe this helps.
For me, renting such a cluster (maybe a 100 machines or so) would be the only realistic way to have a lot of computing power for the bot. Even then it wouldn't be cheap, as each machine costs a few dollars per hour.

I'm curious.... Is the Bot_Ziltoid that you are entering into this year's computer championship any different from Bot_Briareus from last year's championship?

It is different, but not very much. Just a few small improvements (like disallowing 3-for-1 moves) and bug fixes.
