This is a change of topic, since the final score is done by Many Faces'
engine, not the MC playouts. We were talking about MC support for Japanese
rules in order to play well in a game that is being scored by Japanese
Final score accuracy is not perfect under either Japanese or Chinese rules.
Correct scoring by computer is either case is about the same difficulty. MF
is comparable accuracy to gnugo. In test games, the two programs disagree
on the score about 1 in 200 games.

Do you have a good sense of the success rate of your scoring algorithm?
Is it better than Gnugo for instance? Does it get 99% of the scores correct
or is it higher, or lower?
It's my understand that correct Japanese scoring by computer is almost
impossible to get right in every case, although one can come relatively

It is a little tricky to make it work.
