HiTech is a chess machine with special purpose hardware that is capable of evaluating 120,000 positions per second. The hardware is controlled by a [[Sun#4|SUN 4]] workstation running either a brute force or selective search engine. Originally built in 1985 at Carnegie Mellon University, HiTech has since won several computer-computer and human-computer tournaments. Its primary purpose is supporting research into new search techniques. Active research includes a new selective search algorithm and techniques for automatically constructing better evaluation functions.
