matches with inverted colors miscounted in pattern search #64

Closed nanzi closed 2 years ago

nanzi commented 2 years ago

Maybe it‘s a corner case in pattern search. I searched sansan in katago-60b-457 rating games and got 78 matches, which q5go told me 3 matches in white(inverted) colors. But after I counted with screen-print in case of missing or double counting, there were only 2 sgfs.

Excuse me, and what does "136+3=139 matches" indicate? In some search the invert color number is reliable(by coincidence?)

bernds commented 2 years ago

Could be a problem with the symmetry of the pattern causing double counting. Not sure yet.

I think this commit should fix it - please verify whether you still see problems.

Cool. I have compiled the latest commit and both pattern counting (got 2 now) and game sum counting (got 76+2=78 now) are fixed now.
