I don't think the 200+ Elo improvement is so impressive
I agree that it would be much more impressive to report positive
results on larger boards. But perhaps it is already interesting that
tuning the balance of the simulation policy can make a big difference
on small boards? Also, larger boards mean longer simulations, and so
the importance of simulation balancing should become even more
exaggerated.
What komi did you use for 5x5 and 6x6 ?
I find it strange that you get only 70 Elo points from supervised
learning over uniform random. Don't you have any feature for atari
extension ? This one alone should improve strength immensely (extend
string in atari because of the previous move).
Let us extrapolate: I got more than 200 Elo points of improvements from
my patterns in 9x9 over uniform random (I never really measured that, it
may be even more than 200). So maybe I could get 600 more Elo points
with your method. And even more on 19x19.
I noticed that, in general, changes in the playout policy have a much
bigger impact on larger boards than on smaller boards.
