Why odd? It all depends on the bias or policy of simulations. If
there is a flaw in the policy, the score will converses to the score
with some error, which will introduce some limit of scalability, isn't
it?
That is a very good point. Perhaps it is not the case with FatMan,
but that may surely happen. In this study no program is playing with
uniformly random playouts and perhaps only uniformly random playouts
will scale to perfection. Of course, I can imagine that reaching the
strength of Mogo_13 with uniformly random playouts can require a
number of simulations that is not feasible. So I don't have any idea
about how to improve the study, but this is a serious limitation that
has to be considered: If you find some ceiling, the ceiling may be
attributed to the playout policy, not to UCT.
