RE: [computer-go] Computer Go tournament at EGF

["David Fotland" <fotland@xxxxxxxxxxxxxxx>]

This is exactly correct for me.  Many Faces of Go is tuned to play in about
an hour at the
slowest level.  When computers get faster, I add more search, or replace
approximations with
more exact (and slower) calculations, to use the extra time.  The original
Many Faces, in 1984,
ran on an 8 MHz machine, more than 1000 times slower than what we have
today, and played
a game in about an hour.

When I make a change, I need to run enough tests to see if it improves the
program, and if it
is too slow, I can't do testing fast enough.  Part of my testing is playing
games overnight on
IGS, and the players there won't play at slow time limits.
