RE: [computer-go] future KGS Computer Go Tournaments - two sections?

["David Fotland" <fotland@xxxxxxxxxxxxxxx>]

Let me try to explain with a though experiment.  Let's say, without any
data, that Many Faces of Go can beat Gnugo 70% of the time in 100's of test
games.  Both programs can randomize openings, and Many Faces learns, so it
won't lose the same way twice.  I'd be willing to enter a tournament against
one copy of Gnugo, expecting a 70% chance of winning.  I would not be
willing to enter a tournament against 10 copies of gnugo.  It is almost
certain that I would not win this tournament.

I don't understand how anyone can think that this is fair.

Now let's suppose that instead of 10 copies of Gnugo, the tournament has 10
programs that are minor derivatives of gnugo with similar playing strength.
I think it's obvious that this is equally unfair.

It's just as unfair to allow two gnugo versions rather than 10.

For those who would argue that SlugGo is not a minor deriavative, I would
ask them to compare the total person hours of work put into Gnugo and
SlugGo.  I would be surprised if SlugGo has even 5% of the total.

Many Faces has hundreds of tunable parameters, and I don't know which set
plays best against Gnugo.  Would it be fair  for me to enter 10 copies of
Many Faces with different parameter values against one copy of Gnugo?

Marco, if you were in a race against someone, would it be fair to let him
race twice, on different days, and use his best time against your single
time?  How about if he was allowed to train between the races, so it
wouldn't be the "same" person?
