Hi Aja,
Thanks for posting this result.
It seems seki is easy for MC. But semeai and Life and Death are
big problem. Almost all programs don't understand except Zen.
Zen's result is awesome. I think it is a reason Zen is 5d or 6d
and others are 2d or 3d.
About test, this post is helpful.
A Regression test set for exploring some limitations of current MCTS programs
in Go
http://www.mail-archive.com/[email protected]/msg04954.html
Seki 128k playouts
Aya 32/33 96%
Crazy Stone 29/33 87%
GNU Go L10 29/33 87%
GNU Go MC 24/33 72%
Gomorra 26/33 78%
Many Faces 32/33 96%
Pachi 26/33 78%
StoneGrid 31/33 93%
Steenvreter 33/33 100%
Fuego 17/33 51%
Zen 33/33 100%
two_safe_groups_0.3 128k playouts (W two groups are alive.)
Aya 2/15 13%
Gomorra 0/15 0%
Many Faces 2/15 13%
Pachi 0/15 0%
Steenvreter 4/15 26%
Fuego 0/15 0%
Zen 13/15 86%
My anti-semeai version Aya gets
Aya 7/15 46% (anti-semeai)
Aya 1/15 6% (normal)
But I could not get good result on KGS and selfplay from anti-semeai.
Its strength is almost same. Maybe side-effects?
My anti-semeai strategy is
1. Each node searchs its first 100 playouts. Then
2. Semeai analysis runs.
3. Recognize two adjacent groups that has similer living percentage,
like 25% and 28%.
4. Count their true liberties. If one has 2 libs and one eye, 1 share
lib, 5 nakade in the corner include 2 dead stones, etc...
5. In playout, if one reduces his own true libs, undo and play killing
another group move.

Dear all,
If you are interested, you can download the newest version of our
regression test set (seki and two-safe-groups) at
http://webdocs.cs.ualberta.ca/~shihchie/seki-and-two-safe-groups-regression-test.zip
or in Fuego svn
http://fuego.svn.sourceforge.net/viewvc/fuego/trunk/regression/<name>
which contains the results of all participating programs including Crazy
Stone, Zen, Steenvreter, pachi, ManyFaces, Gomorra and Fuego, etc.
Kind regards,
Aja
