EMH/1.14.1 SEMI/1.14.3 (Ushinoya) FLIM/1.14.2 (Yagi-Nishiguchi) APEL/10.3 Emacs/20.7 (sparc-sun-solaris2.7) (with unibyte mode) |
The main pattern databases (patterns.db and patterns2.db) contain a
number of patterns with large fixed values or very large shape values.
Most of these were introduced as workarounds for various severe move
valuation problems before or around 3.0.0. Since then the move
valuation, in particular the territorial evaluation, have been
substantially improved. At the same time, as has been observed many
times, the workaround patterns cause problems on their own. Most
significant are the large shape values which were intended to raise a
low value to a reasonable level but now tend to raise from a
reasonable level to sometimes absurdly large values. The fixed values
don't have that kind of problem but instead tend to be overly general,
causing misvaluations.
This patch removes almost all large fixed values and most of the large
shape values. It also revises some J patterns but there are more of
those which look overly general and/or overvalued as J patterns.
It's possible that some of the workarounds actually are still needed.
I'm fully prepared to reinstate some of them if needed but not without
a test case to point to.
The regression delta is 6 passes:
trevora:470 PASS C5 [!E2]
strategy2:70 PASS N16 [M15|J15|N16|J16]
nicklas5:804 PASS D6 [D6]
trevord:170 PASS Q8 [Q8]
nngs2:180 PASS G16 [G16]
13x13b:8 PASS F10 [F10]
The patch also includes an influence intrusion pattern and a revised
test case in order to solve failures in arend:30, 13x13:16, and
nngs3:800. The influence pattern is somewhat questionable but should
be less problematic than the corresponding fixed values or shape
values.
