Re: [Computer-go] Number of 3x3 patterns

Ah. That makes sense. It's a pattern centered on a possible next move. Very cool. Tysvm for explaining. On Tue, Nov 3, 2015 at 1:33 PM, Detlef Schmicker wrote: > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA1 > > > > Am 03.11.2015 um 20:24 schrieb Jim O'Flaherty: > > I don't

Re: [Computer-go] Number of 3x3 patterns

If you are considering only black stone, white, empty and border, ignoring symmetry, wouldn't it be 3^9 + 3^6 + 3^4 3^9 for patterns away from the border, 3^6 for near the sides and 3^4 near the corners, assuming you are also interested in the center value. This makes 20493, then you need

Re: [Computer-go] Number of 3x3 patterns

I don't see how "leave the center empty" works as a valid case, assuming this it just any valid 3x3 window on the board. Given bots playing each other, there can be 9x9 clumps of a stone of the same color. I can see it being argued there is no computational value in this specific pattern instance.

Re: [Computer-go] Number of 3x3 patterns

Hi Detlef, I have same number 1093 for 3x3 from 4 pro games as symmetory is same pattern. Each point has 4 types, empty, black, white and out of board. 3x3 pattern is small. So recently I combined it with distance of previous move. Each 3x3 pattern has 17 kinds of distance of previous move.
