due to some fluke.
I think this is rather a mischaracterization of why people look for
this. I think people (me included) feel that replacing a whole swath
of relevant information by a single number points to potentially some
serious inefficiency and loss of information. The fact that nobody
has found how to make use of the excess of information is no proof of
course that it can't be done. I think it's a very valid question at
the very least and a bit premature to call it a wrong premise. MCTS
programs are still in their early days of development and it's quite
possible some good improvements can be made by using more information
than the simple win/loss ratio.
