Abstract

Current game-playing programs have developed numerous move ordering and search reduction techniques in order to improve the effectiveness of the alpha-beta algorithm. A critical review of these search modifications is provided, and a recursive formula to estimate the search time is proposed, one which reflects the characteristics of the strongly ordered trees produced through use of improved search enhancements.
