[Computer-go] CrazyStone in the 5-dan footsteps of Zen

[steve uurtamo]

that's great to hear!

there's a categorical and strong empirical difference between players
on kgs that are over 5d from those who are below 5d. it's shockingly
clear in slowish games. i'd love to see a machine at 6d, and expect
that there's nothing stopping it from happening soon.

keep up the great work -- the bigger the pool of strong machine
players, the better for everyone.

I tuned it with CLOP, but I would have probably got the same result if I had tuned it manually (about +100 Elo in self play, both on 9x9 and 19x19). CLOP simply makes tuning a lot more convenient. I really enjoy using it very much. I am glad if people like it too.
