I don't think this specific test had been done. But I'm assuming the result will be the same as previous tests: deviating from winning percentage> leads to a degradation in strength.

Greetings from a lurker,
Forgive me if I am talking out of my hat. It has been a long time
since I have done any real coding.
It seems most of the gains in MC/UCT come fairly quickly (or rather
you can get within 50% of a good move guess with a few iterations).
It would be interesting t
Actually your summary of what people do sounds exactly like what MC
programs do, except for one point...
MC programs don't differentiate moves by point value. They only look
at winning rate. It's extremely tough to differentiate the one move
sequence with 99.1% win rate when all other moves

Interesting analysis, Don.
Human players sometimes adhere to a simple policy: "rich men don't pick fights."
When one is objectively far ahead, one picks up the easy profits, and otherwise
takes no risks. If moves A, B, and C are comparable risk-wise, one would prefer
the more profitable of the

It's me and restarted right now.
Hmmm, I cannot find any strange things in the log file. My guess is
that there are no players other than the anchor running for a while
and the match serv

Yes. I use Sylvain's fpu and decrease it a little before starting a
simulat
I have some sense that it might be possible to slightly improve the
playing strength with some dynamic komi scheme. However, I have also
experimented quite a bit with various ways to do this and in each case I
have been able to detect at least a slight weakening of play.
That probably just mea

Do you have tricks for avoiding redundancies between simulations ?
I suggest simple tricks like "do not go to node X if there is a thread
currently in node X"

Who is running the 13x13 anchor? It is hung and needs to be restarted.

In the last few weeks I have been investigating
Monte-Carlo (MC) game tree search on a rather abstract
level. Especially I was able to "reproduce" the
following behaviour of MC in a very clear model:
MC is playing most "goal-directed" ("zielgerichtet"
in German) when the position is balanced or wh
