[gnugo-devel] more owl tuning

[Gunnar Farneback]

Some more owl tuning. Regression delta:

nngs:480        FAIL F14 [G14]
global:32       PASS G8 [G8]
owl1:285        PASS 1 B3 [1 B3]
owl1:286        PASS 1 B3 [1 B3]
owl1:290        PASS 1 O19 [1 O19]
owl1:292        PASS 1 T4 [1 T4]
nngs3:230       FAIL L12 [!L12]
manyfaces1:100  PASS C19 [!B13|A13]
13x13b:4        PASS F4 [F4]

The failures are more or less accidental. In nngs:480 it must have
been lucky before since the owl reading for F17 was quite erroneous
(it still is). In nngs3:230 the bad move L12 had a high value but the
test passed because E12 was valued even higher. It's possible that the
owl reading for C11 has become worse with the patch but E12 doesn't
look like a very natural attack to me. I think this test case should
be revised to a restricted_genmove test, but I don't understand it
well enough to propose how. There was also a failure in lazarus:13 but
that test is revised by the patch.

- owl tuning
- one test revised
