Example text

If the leaf values are generated randomly using different distribution functions, there is no reason to assume that similar variances should occur. In a real game, however, trees are built and leaf values are assigned according to the rules of the game. , one move) [33]. Since the subtrees beneath them are generated by a consistent rule set, the distributions will probably be quite similar. Differences among their means, then, are much more likely to occur than differences among their variances, and thus the assumptions necessary to vindicate expected-outcome users are reasonable.

For any z-score, the value of can be calculated. A quantile-based evaluation function inputs its relevant parameter zQ into the two Z-l functions, (one for each distribution being considered), receives as output the values Xl == Z1 1 (zQ) and X2 == Z2"l(ZQ), and chooses the best move. Lemma 1: If two evaluators, Qa-outcome and Qc-outcome, recommend different moves, then there is some z-score y, ZQa. < Y < ZQc' for which the two leaf distributions share a common x-intercept. Proof: If a function inputting ZQa.
