Ira L. Ruben, an American computer scientist and former chess programmer. While affiliated with Sperry Univac in the 70s, he was co-author of the chess program CHAOS, along with Fred Swartz, Mike Alexander, Victor Berman, William Toikka, and Joe Winograd and later Mark Hersey and Jack O’Keefe. CHAOS was one of the strongest programs of the 70s and early 80s, using an unique, knowledge based and selective best-first, iterative widening approach, keeping the search tree in memory. Short after the WCCC 1980 in Linz and the playoff for the title versus Belle, Ira Ruben left the CHAOS team to work for Apple Inc..
