minimumNrNodes is the number of games played out. Originally I used to always create a new node when a playout happened. Maybe this should be renamed to minimumNrPlayouts. nrSimulationsBeforeExpansion is the minimum number of visits that have to be made to a node before the tree gets expanded any deeper. As an example, when the search begins, the root-node is expanded with all possible legal moves. But those children nodes are not expanded themselves until a certain number of simulations (playouts) have been done starting from the root-node. Until that time the children nodes are only used to store the AMAF values. I think this may be slightly different from how most people do it, but I figured it would be a waste to throw away the AMAF values for the first 'n' simulations in a node. > Otherwise, it works now. :) Good.
