Hi, Evan:
Regard 13x13:8. In a previous email, you suggested:
One solution might be to devalue ED66 from J to j, and
change ED67 to propose the move at F10, with a
suitable constraint that makes sure the move works.
I made some changes as you suggested (but without
put any constraint on ED67):
Pattern ED66
?x? draw back for safety
O.X
.*O
...
...
---
:8,Oj
?x?
OaB
.*O
...
...
---
; xplay_defend(*,a,*) && !xplay_attack(*,a,B)
Pattern ED67
?x? draw back for safety
O*X
..O
...
...
---
:8,Oj
and run test, I got the result:
Top moves:
1. F10 16.44
2. F11 16.44
3. K1 2.19
..
Checking safety of a black move at F10
Move generation likes F10 with value 16.44
genmove() recommends F10 with value 16.44
my appinion is that: it is basically works, but may
need little more detailed tuning to make F10 has more
value than F11. Factualy, the territory gain of F10 is
only 1 point more than F11, without considering F10
can also connect G9 etc, because which are beyond the
scope of these 2 patterns.
I did read patterns.texi file several times, but I
still dont think I have fully understand how the
whole pattern spec works yet. Eg. Pattern ED67, I
dont know what constraints we should put on and how
to specify them.
Thank you for all your replies and like to hear more
suggestions from you.
Kevin.
