"effective branching factor" is roughly calculated as you mentioned. IE >nodes for iteration N-1 divided into nodes for iteration N. Or you can use >the time. Ok, now I know the terms. Case 2 is what I indeed meant. What equation do you use for EBF calculation. I just thought that maybe one should not use the number of nodes in the equation I gave, but the number of leaf nodes. root_moves*EBF^(DEPTH-1)=leaf_nodes (not total nodes, I think) In initial position you have 20*20^(2-1)=400 which is the number of leaves in ply 2. Using this I have EBF (in Vincent's position) of 3.8. So I still have to improve :) Severi
