If I understand correctly, you have a set of strategies computed for a particular abstraction and wish to get EV (ie game utility) for each player ?
Then you need a full tree traversal.
Just pass the payoffs back and ponderate with action weights and chances weights.
I don't know how you structured your tree but I don't think this :
Code:
number of hole combinaison card in the bucket/169
makes sense.
Anyway, when using CFRM, you should be able to get an incremental utility sum that you can divide by your iterations number.
