Hi,
Your only one computer short of having three sets with two clients. I think that this would be the best compromise. It would enable us to do more simulation than last year, but with a less important decreasing of the cpu power.
For my part, our agents should work on one computer, but it is really border line. I know that we will lost some cycles on the maps with many agents. We have work all year long to develop algorithms that uses as efficiently as possible the cpu power we have, but we tought that we would have at least two computers. We will participate either way, we have invested too much in this competition, but I found it really strange that the comitee wants to change everything just one or two weeks before the competition. Those discussions about the cpu power and the competition itself (learning competition, reducing messages, reducing visibily, etc.) should have been discussed in december, not in june.
That's said, I hope that we will have a good competition and that every team will be able to perform well with those last minute changes.
See you in Lisbon.

To all concerned,
While I agree that there is a significant decrease in computing power since
last year's competition, I find it unlikely that any teams should be affected.
Our agents perform some quite complex analysis at each timestep, using
unoptimized code. What's worse is that it is written in Java. Running all
agents under Windows on a 1.8GHz machine never uses more than 20% of the CPU
time available. Infact, the only problems experienced are network ones.
It seems to me that the time we have available should be sufficient to allow
teams to implement any ideas they have. Particularly since costly processes
can now be pre-processed.
Cheers,
Jonathan Teutenberg.
