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

Is gnu go a weak bot? I suspect the weak bots and gnu go share the common characteristic that they don't resign. I looked at a few games that were lost and it says illegal move to occupied point. On Fri, 2008-07-25 at 21:40 -0400, John Fan wrote: Seems it has a serious bug on end game against
