Go up one level in this thread


I think they usually try to hold cpu constant (e.g., both sides play on same cpu
speed), so the elo ratings are only meaningful in there relative values (x
engine is 30 points better than Y engine).

You make a good point though. IF engines stayed exactly the same as they are now
for th next 10 years, there would not be shifts in ELO, even though the
computers would get faster and faster, and the absolute skill of the engine
would improve.

maybe there should be one baseline computer, e.g., shredder on a p2. This engine
and computer could be used to norm the other computers for awhile (until the
newest computers beat the p2 everytime..then you would have a floor effect).
