Please note that pachi1 had a rather embarassing bug of starting the
random playouts with wrong color (so if the last tree node was black,
the playout would start with black as well). pachi2 has this bug fixed;
the ELO rating is still not settled, but so far it seems that the impact
of this has been about 20-30 ELO in the 110k playouts area, which seems
surprisingly little to me.
(-moggy is playout policy that so far comprises merely of capturing or
escaping of random stone in atari, with some ladder reading; I'm happy
that I managed to get as high as 1750 with just this addition! I'm not
sure how much strength the ladder reading actually adds, it did not seem
that much of an improvement (relatively to the time spent debugging it)
from playing it; I will test that later.)
