So far i've tested with 180k simulations, 16 threads:
pachi -t =180000
With the opening book it's always playing the same opening but speeds up
No idea what the right dcnn_eqex might be for different settings, i've
only tested with this so far. Even there it can still probably be
improved (1400 looks good too, 1200 & 1500 definitely worse ...)
The github branch is a cleaned up version of the tree i'm using for
testing, hopefully i didn't screw up (haven't tested it yet).
One thing that's missing in it is PR#26 (check group suicides), it can
assert out in the endgame otherwise. Also right now dcnn disables
pondering, would be nice to find a way to make it work again for
I don't have a gpu so hard for me to experiment, but sure would be nice
to have support for that ! Wow, it would really start to look like
darkforest then =)
I'm thinking even multi-threaded cpu support might be good enough to
start using it further down the tree...
Btw do you know what's going on with monkey jumps ?
For some reason it seems it never plays them, i suspect there's
something strange going on... Playout issue maybe ?
