[gnugo-devel] owl tuning

[Gunnar Farnebäck]

Here is an owl tuning patch. The regression results are:

ld_owl:69       PASS 1 T16 [1 (T16|T18)]
ld_owl:324      PASS 1 N2 [1 N2]
neurogo:3       FAIL Q3 [H3|K3|K4]
owl1:354        PASS 0 [0]
gunnar:68       PASS D8 [D8]
gunnar:70       PASS A18 [A18|A13]
9x9:360         PASS D5 [F4|E6|D5]
olympiad2004:10 PASS B15 [B15]
7 PASS
1 FAIL
Total nodes: 1673158997 3161265 13120985 (+0.072% +0.072% +0.044%)

The neurogo:3 failure involves the owl reading of the lower right
corner. It's not obvious to me what the correct result should be there
or that Q3 is any worse than the accepted moves in the test case.
