I agree that the komi should not be changed unless there is a very
compelling reason. My engine would have to be entirely recreated to
support a different komi and I only want to maintain one engine for
each boardsize.

I suspect that quite a few of the odd scores are not due to the
presence of seki with an odd number of neutral points but are caused
by uncaptured dead stones.
Which program (or programs) is most reliable at determining life-and-death and

As programs become stronger the advantage for one side with fractional
komi will inevitably become totally unbalanced. At some point we will
approach 100% and then I rather have that go to the first player. The
only fair alternative is to use integer komi.
Or a bigger board.

It seems like most reasonable sequences in Chinese rules 4x4 go end in
a whole-board seki. I would expect that for 19x19 go, some avenues of
best play

This may be true for your CGOS games.

I'm not sure if it's wise to ignore games lost on time. For a MCTS
program it makes sense to adjust the time taken for the move based on
its perceived chance of winning. But that means a program is more
likely to lose on time because it's losing anyway, and that judgement
involves the

From all we know so far it is most likely that perfect komi is 7.0.
Even numbers lik 6.0 and 8.0 are unlikely because they always require
a seki with an odd number of shared liberties (in all optimal lines!).
Since IMO the first player should have a chance to win it seems
natural to set the komi
