- experimental influence: yet another new_value_territory revision
- experimental influence: fixed followup values really taken down (shapes.c)
- experimental influence: pattern tuning
new_value_territory now combines the two approaches I tried for devaluing
center territory. There is a reduced direct center correction, and
an erosion step; however, permeability now gets to control the erosion,
which means I do not have to shift any barriers. This center correction
might still be suspect to some fine tuning.
With my last patch, I had forgotten to add the check for Y-patterns
(i.e. those depending on experimental_influence setting) in shapes.c. So
the retirement of almost all fixed followup values in experimental
influence is only effective now.
After this patch, --experimental-influence produces 58 PASSes and 53 FAILs.
which is quite dubious, of course. However, my personal impression was
that the current state should already be an improvement in playing strength
compared to standard influence.
There are numerous regression cases where GNU Go's assessment of the
position was wrong, but it happened to play the right move. As the change
of the territory valuation does changes every single valuation, this can
both cause previous accidental passes to turn into a FAIL and vice versa,
which makes the regression results a quite unreliable benchmark for the
territory valuation.
So I decided to go through the tedious exercise of systematically looking at
all the PASSes and FAILs. Below is a list with short comments.
My conclusion is as follows: I still think that there is a substantial gain
-- if there would not remain one big problem. This is the overvaluation of
invasion moves. This turns up in a number of tests in trevorb in 13x13-games.
(Here, the influence module values the approach move to hoshi's with
20-25 pts, which is not too unreasonable. However, from various patterns
it gets a strategic attack bonus of ~10pts, making GNU Go tenuki from
joseki. The strategic bonus is inappropriate as the approach move is
weak itself.)
However, there are two or three cases where this turns up on a 19x19-board
as well, producing some strange moves there (see nngs:900 for an
outstanding example). I am a bit reluctant to change this via influence
tuning, as the territory valuation is not far off in most cases; I fear
that artificial changes to work around this may loose precision in
other cases.
Instead I would like to assign a negative strategical value of maybe
5-10 pts for moves that
1. are played in the opponent's sphere of influence
2. are not connected to a friendly living dragon
3. have weak escape value.
A good handling of this problem would also be a precondition to a special
moyo-reduction move generator.
I am not quite sure how to implement this, as value_moves does not seem
to know about the second condition. Maybe I will just drop it and rely
only on the escape value for this part. Probably I should not yet use
connection readers for this? Any other idea?
Once this is done, I think we could start playing 2gtp-matches of standard
vs experimental influence to see whether my general impression is right.
Certainly there will still be room for improved influence tuning, but
I would not expect any substantial changes anymore. So this should not be
an obstacle to making --experimental-influence default.

140 unexpected PASS! luck
430 unexpected PASS! urgent (cvs PASSes as well)
450 unexpected PASS! good
530 unexpected PASS! luck

20 unexpected PASS! good
22 unexpected FAIL: Correct 'K3', got 'J11' (not very) bad;

./regress.sh . neurogo.tst
8 unexpected FAIL: Correct 'O2', got 'Q5' owl fault
28 unexpected FAIL: Correct 'O2', got 'Q5' owl fault
both are an owl problem, M3 is assumed to be alive
(otherwise O2 would get a followup bonus from saving M3)
./regress.sh . rosebud.tst
1 unexpected FAIL: Correct 'E16', got 'E18' ?
GNU Go thinks E18 kills the corner; strange it preferred E16 before
./regress.sh . golife.tst
4 unexpected PASS! not urgent
./regress.sh . viking.tst
3 unexpected FAIL: Correct 'M15|B7', got 'Q3' bad
difficult to solve (Q3 saves Q4 but Q4 cannot be killed cleanly,
so Q3 is not so urgent)
7 unexpected PASS! good
local problem not solved (connection problem), but moyo reduction
at P12 preferred
9 unexpected PASS! good!
./regress.sh . lazarus.tst
4 unexpected FAIL: Correct 'R12|Q12|M8', got 'T5' bad (bit lucky before)
16 unexpected PASS! luck

See discussion above.
450 unexpected PASS! luck
500 unexpected FAIL: Correct '!J11', got 'J11' bad, but hardly related
520 unexpected PASS! good
600 unexpected PASS! good
(F2 get followup, G1 does not)
620 unexpected PASS! good (cvs PASSes as well)
660 unexpected FAIL: Correct 'D3', got 'H5' (not very) bad
GNU Go cannot judge territory correctly that is open at 2 sides
700 unexpected PASS! very small gain

reverse followup at A6 too large
840 unexpected PASS! luck
960 unexpected PASS! luck
./regress.sh . strategy2.tst
51 unexpected FAIL: Correct 'P3', got 'N5' bad
before, it passed only due to minimum move value of P3. N5 gets
a little to high terr. valuation (~23) + strange shape bonus and a
little to high strategic bonus
53 unexpected PASS! good (cvs PASSes as well)
85 unexpected FAIL: Correct 'O2', got 'N5' very bad
This does show a problem of the territory valuation, N5 is
overvalued. However, a strategic minus for creating a heavy group
by running away with a stone in front of opp's group
90 unexpected FAIL: Correct 'B14|D17', got 'H2' bad (?)
91 unexpected FAIL: Correct 'B14|G13', got 'H2' bad (?)

800 unexpected FAIL: Correct '!N19|M19|L19|S18|K1', got 'K1'
This is not reproducible. Also, it was luck it passed before.
A lot of valuations look strange here.
850 unexpected PASS! good!
900 unexpected FAIL: Correct 'Q15', got 'Q7' very bad
1020 unexpected PASS! good
1050 unexpected PASS! good
1080 unexpected FAIL: Correct 'K17', got 'F3' good
bad problem

1760 unexpected PASS! good-
1790 unexpected PASS! oops?
1800 unexpected PASS! no improvement (Q14)
1920 unexpected FAIL: Correct '!L11', got 'L11' bad luck

should be solvable with pattern tuning
600 unexpected PASS! no improvement (D9)
610 unexpected PASS! not reproducible
750 unexpected PASS! good-
1080 unexpected FAIL: Correct '!L8|K10|K9', got 'L8'
I don't understand the point of this problem. Will W L8 really die?
Is M10 really better?
1240 unexpected PASS! some luck, strange position
1290 unexpected PASS! good
1310 unexpected PASS! good
1340 unexpected PASS! good-
1350 unexpected PASS! good!
1370 unexpected FAIL: Correct 'B9', got 'C9' nothing wrong with C9
1400 unexpected PASS! good, some luck

./regress.sh . connect.tst
37 unexpected PASS! huh?
./regress.sh . global.tst
5 unexpected FAIL: Correct 'O4', got 'S12' bad, but also strategy fault
rrgs. However, I think he reason why O4 is preferable is the
cutting value N3/P3 and the cut potential at N5. Both are not
implemented/undervalued at the moment.
16 unexpected FAIL: Correct 'O10', got 'P12' bad luck
cvs has same problem
28 unexpected PASS! good
./regress.sh . arend.tst

but I am not really sure what caused this pass
32 unexpected FAIL: Correct 'F9|E8', got 'G8' ok
problem wrong
33 unexpected FAIL: Correct 'F9', got 'M5' bad luck
completely lucky it passed before, the connection problem
remains to be solved.
./regress.sh . 13x13.tst
17 unexpected FAIL: Correct 'L5|L3', got 'G8' bad (some bad luck)
L5/L3 (combination attack) should get awarded some strategic
bonus
33 unexpected PASS! luck
38 unexpected FAIL: Correct 'G11', got 'E3' very bad
41 unexpected FAIL: Correct '!C8', got 'C8' bad luck
43 unexpected FAIL: Correct 'D6', got 'B6' ok
B6 is not necessarily worse (GNU Go does realize it leaves a
gap in the center)
76 unexpected FAIL: Correct 'K6|L6|J3', got 'J5' ok
J5 fits quite well here I'd say, shows GNU Go trying to build moyo.
85 unexpected FAIL: Correct 'D2', got 'B10' looks ok
88 unexpected PASS! some luck
./regress.sh . trevord.tst
180 unexpected FAIL: Correct 'S9', got 'O5' bad
should be fixable with pattern tuning
240 unexpected PASS! good!
moyo reduction at L8; position of L8 could be improved, though.
550 unexpected FAIL: Correct 'T8', got 'J8' ok
I think this is ok. F8 is a weak group, and Black is threatening
a moyo while attacking it.
590 unexpected FAIL: Correct '!N14', got 'N14' bad luck
710 unexpected PASS! good
830 unexpected PASS! good
./regress.sh . strategy4.tst
190 unexpected PASS! good
194 unexpected FAIL: Correct 'A13', got 'D6' bad, some bad luck
hmm, GNU Go thinks D6 captures D8; this is not mentionend
on Trevor's trace file -- another platform dependency?
200 unexpected PASS! luck
204 unexpected FAIL: Correct 'B2', got 'G6' (not very) bad
207 unexpected PASS! good
209 unexpected PASS! not reproducible
