I threw it at Google translation, which is supposed to be the best machine translator available now, using only Bayesian statistics with no knowledge. It mangles it, but the meaning comes through. It sounds like an interesting article. It would be nice to have a good translation. David Drosophila's luck and end God regarded everything, which it had made: It was very good. It became evening and it became morning: the sixth day. Towards. 1,31 If I intend a larger financial transaction, I ask a friendly economist over the prevailing opinion to this topic. Then I with some security, like it does not become white and does not depend on it. In my Profession is still simpler the thing. The prognoses John McCarthy's and its AI-young form an entropy set. The area of the hopeless solutions. Stanley Kubrick' s HAL and my Windows PCs have only one together: Sometimes goes nothing at all more. 1989 published J. Schaeffer and M.Donskoy Perspectives on Falling from Grace. The Confessiones of two successful academic chess programmer. One betrayed the holy goal of the computer Drosophila by the longing of the tournament victory. Schaeffers Bekehrungserlebnis was a bitter defeat against chip test. It became again backdue however with the lady program Chinnook. 1989 I worked in the European space Technology Centre in Noordwijk/NL. In the damp and cold winter evenings I felt lonely and had homesickness. Around this feeling to betäuben I bought the Mephisto Polgar Brettcomputer of OD Schroeder. Playing against helped also nothing and seized I one evening the resolution in such a way: I can bisserl games of chess, I can program, why I do not make a chess program? The goal was, a PC program, which can take up it with that. I had increased thereby the drug, became sufficient depressing drums of the rain the pleasant mood music. However I suffer until today from heavy craze features. Of the McCarthy' Drosophila did not have I the smallest rope, McCarthy was me only as a creator of its own programming language a vague term. It would have been also perfectly all the same me: My goal was to betäuben and strike homesickness. 1989 rank among the sieved fat years of computer chess. OD Schroeder lives this very day of the pole percentages of profits. 1989 defeated chip test the first large masters. The first article over this program carried the title by program for Designing A single chip Grandmaster while knowing emergency-hung about chess . Chip test attained as Deep Blue world fame. John McCarthy, which had formulated the victory over the chess world champion once as warming up exercise for the actual tasks of the AI, reacted in a book review in Science to Deep Blues summit victory säuerlich. Three feature OF of human chess play acres required by computers programs when they face of harder problems than chess. Two OF them were used by early chess programs but were abandoned in substituting computers power for thought. 1) Human chess players CAN emergency examine all moves RK every position they think about and therefore must forward prune the move tree and SELECT the more promising moves for exploration; early chess programs thus pruned. About of 1969 forward pruning which eliminated, and computer power which relied upon ton examine all moves. It larva the programs work more better, because early programs sometimes pruned good move. Eliminating pruning which possible, because there acres only about 40 moves in A position. In the game OF Go, there acres UP ton of 361 moves in A position, then even computer forward prune must. McCarthy ignored obviously 30 years development. Modern programs look for not brute force, but use dynamic information, the structure of the search tree, in order to extend and shorten variants both. My chess program Hydra looks for 17-18 sections in a central play position deeply. The shortest variants have a length of 7, the longest up to 40 Plies. Contrary to the punch card age one uses today softly pruning . Instead of completely cutting a course off, the search tree is shortened. A search tree reduced by 2 Plies is not many more expensive to omit than the course at all. The program has however the chance to recognize incorrect Pruning in the following iterations while the method publicised by McCarthy does not correct the error with infinite search depth any longer. In addition these shortened searches produce further information about the search tree, which can be used in consequence profitable. Most programs compute only the first 3 courses brute force , those remaining courses are strongly geprunt. The optimal exponential factor amounts to with alpha beta 6, actually has the programs a factor of 3-4. Without search extensions the factor would sink under 3. For Fritz programmers fray to rotten lies therefore the intelligence of a program in the search algorithm.
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of chrilly Sent: Saturday, May 26, 2007 7:49 AM To: computer-go Subject: [computer-go] Yet another article Attached is an article (in German) I wrote for a special Go edition of the Austrian Journal for AI. The article was fortunately not accepted. "it does not fit to the journal". I aggree - for different reasons - with this statement. The decision is fortunate, because the article will be published now in a normal magazin which pays and which has also more readers. Its no classical scientific article, but a "scientific essay" which deals with God, the prophet J. McCarthy and the state of the art in computer-chess and go. I have developed this sort of writing in the last years for a column in the chess magazin "Kaissiber". Its inspired by "De Koning" (Engl. The King), a collection of articles of the Dutch GM J.H. Donner. So far the articles have been translated to Dutch and Italian and sometimes the editors think that they have to translate it from Austrian to German before publishing. I have also done - together with my wife - some authorized translations of Donner articles from Dutch to German. I collection of (better) articles can be found at http://www.lbremer.de/chrilly.html, according my wife the best story is Eine Semmel fuer den Bello on http://www.chessbase.de/spotlight/spotlight2.asp?id=13 Chrilly P.S.: I have attached the article, because I have no homepage.
