Hi,
It seems that e-mail at my university does not work any more. I have
received none of the replies to my message of yesterday, but I could
read them on the web archives of the list. So I have registered from
another address, and will answer to the questions I have read on the web.
to Matt: In Crazy Stone, UCT is still used as before to select moves.
Patterns are used to shorten the list of moves that UCT considers.
to Sylvain: Here are tests of Crazy Stone at 90s/game 1CPU against GNU
3.6 level 10, measured over about 200 games:
no pattern: 38.2% (version available on my web page)
patterns in simulations:68.2%
patterns for pruning and simulations:90.6%
I found these number in my history of Crazy Stone versions, so they may
not be extremely accurate, because other things have changed in between.
I will run cleaner tests for the final version of the paper. I will also
try to test what each feature brings.
to Magnus: If you consider the example of section 2.2: 1,2,3 wins
against 4,2 and 1,5,6,7. The probability is
P=c1c2c3/(c1c2c3+c4c2+c1c5c6c7). For this example:
N1j=c2c3,B1j=0,M1j=c2c3+c5c6c7,A1j=c4c2
N2j=c1c3,B2j=0
N3j=c1c2,B3j=0
N4j=0,B4j=c1c2c3
I will add this example to the paper if it makes things clearer.
Regarding the definition of Wi, |{Nij|Nij!=0}| means "number of elements
of the set of all the Nij that verify Nij!=0". It is incorrect. It
should be |{j|Nij!=0}|. I'll fix it in the final version. As I wrote in
the next sentence, it is equal to the number of wins of i.
Thanks to all for the kind words, and the interesting remarks and questions.
Rémi
