The utility of CGOS wouldn't change except for the better. The way it
works is this:
After each game:
1. The ill-behaved bot gets rated by the full formula.
2. The opponent of the ill-behaved bot gets a smaller adjustment
than usual.
The adjustment for the opponent would approach zero if the ill-behaved
bot had a serious problem. The utility of CGOS for such a bot isn't
very high anyway since the results for it have little meaning. So
the rating adjustment for the opponent should be correspondingly small,
reflecting that the results is almost meaningless for the opponent.
That seems only fair.
Go ahead, play mirror go if you wish. What is your answer to 1. e5
? Or what is your first move if you are black? I don't think you
have much to work with but you are welcome to try it. CGOS is open to
every bot - as long as you are not malicious or buggy in an annoying
way. I would prefer that bot's that play random moves do not
play, but that is a request not a rule.

I can't think of any really clever way to handle this. Here is
about the best I can think of right now:
Keep statistics on each program - how often it loses due to time or
illegal moves. Use those statistics to reduce the impact of the
rating formula. I could arrange it so that even if 10% of your
games are lost that way, your rating becomes highly suspicious and
given very little weight in the rating formula. This basically
amounts to treating the games of such players as if they were
un-rated games. - Don
Wouldn't that drastically reduce the utility of CGOS for experimental
bots? I guess it depends on what you want the server to be, whether
you want as many as possible the chance to get a ranking, or whether
to get as accurate a ranking as possible. And can rankings really be
accurate in any case, with just bots playing bots?
It brings me to another topic I've been considering. If I use mirror
go as an opening strategy for a bot, will that be looked upon
unfavorably? It seems that when most of the opponents a bot faces will
be stronger opponents, mirror go, with some sensible logic on when to
break out of it, would be the optimal opening strategy. But somehow I
got the feeling that a lot of people would be yelling at me if I used
that in any kind of ranked or competition setting, no matter how
informal.
