Igor Steinberg [1]

Igor Steinberg,
an American computer scientist, solution architect, teacher, and program manager, with director-level IT executive experience in the higher education, government, and private sector [2]. He holds a Ph.D. from University of Wisconsin-Madison in 1991 on the topic of parallel game tree search [3], and researched and published along with his thesis advisor Marvin Solomon on a parallel game tree search algorithm dubbed ER algorithm.

ER Algorithm

Abstract [4]

We present a new parallel game-tree search algorithm. Our approach classifies a processor's available work as either mandatory (necessary for the solution) or speculative (may be necessary for the solution). Due to the nature of parallel game tree search, it is not possible to keep all processors busy with mandatory work. Our algorithm ER allows potential speculative work to be dynamically ordered, thereby reducing starvation without incurring an equivalent increase in speculative loss. Measurements of ER's performance on both random trees and trees from an actual game show that at least 16 processors can be applied profitably to a single search. These results contrast with previously published studies, which report a rapid drop-off of efficiency as the number of processors increases.
