No, if no patterns or tactics are triggered all moves has the same
priority and are played uniformly as usual. It is only sequences that
trigger forced moves that are deterministic, and in many cases two or
more moves with the same priority is triggered too and then there is
random choice between these moves.

Quoting Peter Drake <[EMAIL PROTECTED]>:
Without the 10% random moves, would every playout from a given leaf be
identical?

Valkyria plays uniformily the highest ranked move. Ladders as a
response to the last move are almost always ranked above all else.
But it has a parameter that makes it play any move with 10%
probability no matter what the tactical situation is on the board.
I have not tested if these really is beneficial. If it is it is
probably really a small change to winning rate.

I hope you don't mind me chiming in here. I think I asked this
question quite recently on the mailing list and the reply I
received from Magnus Persson (I hope I am not misquoting him) was
that Valkyria adjusts the probability distribution based on a
simple ladder readout which is a function which returns either
success fail or unknown in order to feed this information into
the playout process.

Can you say more? Do you mean ALWAYS play such moves first
if they
are available, do so with some probability, or what?
