Without the exploring term, the UCT is just mean win rate, so there's no
point in calling it UCT or UCB. Basically, what people have been saying is
that currently the tree search is based on combination of sequence dependent
rate (average win rate) and sequence independent/almost independent (rave
rate) instead of combination of exploitation (win rate) and exploration (UCB
term). Is this understanding close?
