Heiner, from what move exactly branching went up? On mine is started growing
just from 6. It could be that I just stopped where it must explode.
If you want to glace brute force:
Moves Time Branching factor NPS
4 1.26sec 77k
6.65
5 8.4 sec 120k
6.63
6 55.77 124k
8.78
7 8min 3sec 116k
8.17
8 1 hour 5 min 48 sec
Cheers,
Leonid.
