From: Heikki Levanto [EMAIL PROTECTED] I still think it a bit strange that on an empty board, a program can prefer a 3-3 point in one corner, and in another corner find it quite unplayable. It makes sense of the space evaluated by the random playouts differed. But my thinking is, what if

on 9x9 it's easier to see it converge. 19x19 is a beast, which is why i think that scanning a small slice of the board for the first two moves might not be such a bad idea. s. Fussy? Opinionated?

By the way, byo-yomi is not a very logical system. It has the characteristic that you are penalized for playing quickly. If you play quickly the time should be credited to you.But byo-yomi seems more interested in forcing a player to play at a steady pace and doesn't allow much control over

But I would still like to know how many MC evaluations it would take until all corners look at least somewhat similar... I bet that is many more than we see used currently - if it ever gets there. The approach I take in Valkyria is radically different. I simply prune all symmetric moves. For
