Title
A Minimax Algorithm Better than Alpha-Beta? No and Yes
Abstract
Abstract This paper has three main contributions to our understanding of fixed-depth minimax,search: (A) A new formulation for Stockman’s SSS* algorithm, based on Alpha-Beta, is presented. It solves all the perceived drawbacks of SSS*, finally transforming it into a practical algorithm. In effect, we show that SSS* = α-β + transposition tables. The crucial step is the realization that transposition tables contai n so-called solution trees, structures that are used in best-first search algorithms like SSS*. Having created a practical version, we present performance measurements with tournament game-playing programs for three different minimax games, yielding results that contradict a number,of publications. (B) Based on the insights gained in our attempts at understanding SSS*, we present a framework,that facilitates the construction of several best-first fixed-
