Hi Hiroshi, I try to layout my approach: - expandLeaf: expands a leaf node, after being visited 10 times (a parameter, but increasing it usually did not harm playing strength significantly) it contains a if (!expandmutex.try_lock()) return false; which was in the code anyway to avoid, th

A CNN that starts with a board and returns a single number will typically have a few fully-connected layers at the end. You could make the komi an extra input in the first one of those layers, or perhaps in each of them. Álvaro. On Sun, Jan 11, 2015 at 10:59 AM, Detlef Schmicker wrote: > Hi,
