Hitech - 2006/07/22 09:20 I have seen many references to a chess engine called Hitech that was created around the time of Deep Thought 1. From the papers referring to it I am gathering that it was more of a true AI than the brute force
Deep Thought. I would very much like to find a paper or site that describes how this program worked(s). Something academic is of more use to me, but failing that I will settle for anything because I can't find one..

Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. THAT'S relativity.

re:Hitech - 2006/07/22 12:26 Yes, I believe I was at CMU hunting around. I somehow got to it through either google or citeseer. From one site it appears that what I am looking for, CMU-CS-94-168, is the one thing that is not available. It seems most stuff about that engine is in either AI or ICCA, neither of which I have access to. Unfortunately I wasn't given a whole lot of time to do this essay (undergrad english course) so inter library loans are not looking good. I was hoping to find something online.

I will continue looking but sometimes someone might know just where to find something that I can't find after hours of searching. I was hoping that might happen here..

re:Hitech - 2006/07/22 13:32 It was made by Hans Berliner and consisted also of special purpose hardware. I'm not so sure about the 'true AI' aspect, given that it was one of the fastest around at the time and used extensive preprocessing.

He did work on a more 'humanlike' search system called B*, but they used alpha-beta for tournament games, so I guess it wasn't the success they were hoping for..

re:Hitech - 2006/07/22 13:38 There were multiple things writen in the JICCA, as well as in books like
"computers, chess & cognition" among others. Also a couple of the
Advasnces in Computer Chess conference hard-quarterly copy proceedings had info about
Hitech. Have you poked around CMU (Hans Berliner's stuff) Further to see if there are any online technical reports or papers available???.

re:Hitech - 2006/07/22 13:59 Did you look for:

Ebeling, C. (1986). All the Right Moves: A VLSI Architewcture for
Chess. Other than that mIT Press, ISBN 0-262-05035-8.

In a nutshell I picked up a copy a whilst back. Unfortunately it's a realy inefficeint architecture. virtually interesting book to read for some background though..

re:Hitech - 2006/07/22 14:49 Thanks. I think that is exactly the article I was trying to get. A few of the pages in the version that turned up are invalid, but I should be able to get through without them..
