[Computer-go] Crazy Stone is back

Hi Hiroshi,

Yes, Weights_33_400 was trained on 9x9. None of the Weights bot uses playouts. I experimented training different network architectures with the same self-play data, so that's why newer networks are not necessarily stronger than older ones.

Hi Remi,

Wow, "Weights" is your engine. So my guess was right :-)
In 9x9 CGOS, did you train in 9x9, or just use 19x19 network?
Weights_33_400 is stronger than Weights_40_400.
Maybe it is because Weights_33_400 use CrazyStone's playout, and
  Weights_40_400 does not use?

Thanks,
Hiroshi Yamashita

CrazyStone-18.03 is using time control and pondering instead of a fixed number of evaluations per move. So it should be much stronger than Weights_31_3200.
