AW: [gnugo-devel] owl tuning

[Portela Fernando]

Hi,

Just to mention it : with my Win32 build, I'm experiencing a cache
effect on that nngs3:250. When regressing the whole nngs3.tst, 
it passes, but no longer when tested alone. VC specific ?

Betreff: [gnugo-devel] owl tuning


This patch splits the owl pattern D1361 into two and revises the
constraint of one of the parts. The regression result is a PASS for
nngs3:250 and node changes of +0.026%, -0.38%, +0.62% for reading,
owl, and connection nodes respectively. Since owl nodes are most
expensive this probably translates into a very small speedup.
