If so, then I can see how the play-out would miss this.

While bigger examples exist, 4 in a line (with both ends enclosed) is not

This is probably massive overkill, but one of the most
successful techniques for multi-parameter optimization
is Taguchi methods.

However, in my experience, starting with the decisions
that make the biggest difference, and then adding

By the way, does anybody know of any nifty tools or heuristics for
efficient probabilistic multi-parameter optimization? In other words,
like multi-dimensional optimization, except instead of your function
returning a deterministic value, it returns the result of a Bernoulli
trial, and the
My program Aya637_4CPU is top on 19x19 CGOS now.
It is temporary, but I'm so happy!
Please don't run full power MoGo, Crazy Stone and Leela :-)
My main improvement was
1. Do not move dead stones.
Before doing playout, Aya does string capture search up to 7 plies(ladders
are extended). And set
Congratulations! I'm really impressed with how fast the AyaMC improved.

Have you selected the room with bot's name as a member?
Yes. Seemingly only public rooms are possible for bots.
I'm interested in if someone has a solution for private rooms.
