How would I code this in C++ to >get this 3.9 value? My math skill since high school has gone down tremendously. Yes, I wrote this: "So it means (DEPTH-1)th root". So DEPTH-1 is the N. In C you can use math.h library. And this is where you'd need a little math since math.h doesn't have a function which returns Nth root. It has a function pow(x,y) which returns x^y. And you can take Nth root from x by x^(1/N) which is pow(x, 1/N). So below is the correct expression. ebf=pow(leaf_nodes/legal_root_moves, 1/(DEPTH-1)); Severi
