[gnugo-devel] Patch: removal of value()s from patterns.db

[Inge Wallin]

When I was working on the strategic bonus, I got a FAIL that was due
to an explicit pattern setting a value for a move to 30.  I think it
was ED45.  Removing this value, fixed the FAIL. 

When thinking of it some more, I decided that explicit values of this
size were bad, so I wanted to see what happened if I removed all
explicit values, 10 and above.

Well, the result was much smaller than I expected: 1 PASS and 1 FAIL:

./regress.sh . trevora.tst 
470 unexpected PASS!
./regress.sh . strategy2.tst 
79 unexpected FAIL: Correct 'N3', got 'Q6'

Looking at strategy2:79, I don't think I agree that Q6 is the only
viable move.

I didn't touch the high handicap patterns, nor the reinforcement
patterns, only the ordinary patterns.  I think the reason for the
small regression delta is that these patterns are simply rests from
the old engine, and that we have much better machinery for deciding
values of moves today.
