World Class PC, Mac and Palm Chess Software on your desktop and in the Palm of your hand! HIARCS 9.0 for PCs A chess program which can do more than calculate! The latest version 9.0 of the program has been enhanced and extended in many ways, particularly in terms of implementing concrete chess knowledge and positional learning. With the improved search function, it's now possible to assess positions using new positional criteria such as “typical pawn structures”, “long term plans” and above all “safety of the king”. A better selection of variations provides a greater search depth, enabling Hiarcs 9 to impress by its sharp powerful play against the enemy king as well as its better understanding of endgames, even with unbalanced material. A special asset of Hiarcs 9 is the opening book, which has been finely adjusted to the playing style of the program. This is the work of computer chess expert Eric Hallsworth, who has been developing the Hiarcs opening books for many years. For Hiarcs 9, he has compiled an optimized and many-sided repertoire with a wealth of novelties. Developer Mark Uniacke himself says about his new program: “A major improvement is the king attack enhancements. Hiarcs' play can now be really exciting. Also the learning and the positional understanding has been clearly improved. I suggest to you that the king attack enhancements (the play can be really exciting), learning, positional understanding (Hiarcs has a reputation as a positional player) and the overall strength are now clearly on a par with the top engines.”

46. MAKING COMPUTER CHESS SCIENTIFIC (20-Sep-1998) Kasparov that the tournament oriented work on computer chess was not contributing computer chess and human chess gives an example of a problem quickly http://www-formal.stanford.edu/jmc/chess.html

MAKING COMPUTER CHESS SCIENTIFIC Up to: Main McCarthy page I complained in my Science review of Monty Newborn's Deep Blue vs. Kasparov that the tournament oriented work on computer chess was not contributing as much to the science of AI as it should. AI has two tools for tackling problems. One is to use methods observed in humans, often observed only by introspection, and the other is to invent methods using ideas of computer science without worrying about whether humans do it this way. Chess programming employs both. Introspection is an unreliable way of determining how humans think, but introspectively suggested methods are valid as AI if they work. Much of the mental computation done by chess players is invisible to the player and to outside observers. Patterns in the position suggest what lines of play to look at, and the pattern recognition processes in the human mind seem to be invisible to that mind. However, the parts of the move tree that are examined are consciously accessible. It is an important advantage of chess as a Drosophila for AI that so much of the thought that goes into human chess play is visible to the player and even to spectators. When chess players argue about what is the right move in a position, they follow out lines of play, i.e. argue explicitly about parts of the move tree. Moreover, when a player is found to have made a mistake, it is almost always a failure to follow out a certain line of play rather than a misevaluation of a final position.

Chat Monitor page for changes it's private by ChangeDetection (My PGP key) Introduction This page was initially part of my web site on setting up of Winboard engines . However, I discovered that many visitors to my site, were actually looking for information on setting up endgame tablebases. Given the fact that my Winboard web site was already very long, I decided to start a new web site using the information already available in the original page as a base. I added information from the various web sites and past posts at Rec.games.chess.computer and the Computer Chess Club. I'm a layman who is largely unfamiliar with the technical details of endgame tablebases. As such much of the technical detail here is only available thanks to the kind permission of experts such as E.A. Heinz,Guy Haworth, (both frequent contributors to ICGA journals on this topic) Anders Thulin (from rec.games.chess.computer ) , Robert Hyatt, Bruce Moreland and especially Dieter Buerssner (all of those are authors of strong chess programs that use endgame tablebases). I would be grateful if you can email me if you spot any errors.

Thanks guys. Why run a computer chess tournament? Running a computer Chess tournament is a long and thankless task that will tie up your computer for days . Many people feel that such tournaments [referred to as "Basement tournaments"] are merely a waste of computational resources. Despite this, many computer Chess enthusiasts still eagerly spend much of their free time running such tournaments and the reasons why they do so vary. Some do it because, they want to assist authors of their favourite programs as beta testers, others do it because they have the need to find out once and for all the best program or to prove a point, and yet others do it because they enjoy watching the computers battle it out and enjoy playing through the resulting Chess games.

Computer Chess Programming Chess Program Sources Computer Chess Books Chess Tree Search Tree search is one of the central algorithms of any game playing program. The term is based on looking at all possible game positions as a tree, with the legal game moves forming the branches of this tree. The leaves of the tree are all final positions, where the outcome of the game is known. The problem for most interesting games is that the size of this tree is tremendously huge, something like W^D, where W is the average number of moves per position and D is the depth of the tree, Searching the whole tree is impossible, mainly due to lack of time, even on the fastest computers. All practical search algorithms are approximations of doing such a full tree search. These pages give an overview of traditional, fixed depth minimax search, with various refinements such as selective extensions and pruning, as used in most modern chess programs. There are other, more experimental, game tree search techniques that take a different approach, like e.g. B* and conspiracy numbers, which I hope to describe at a later time. This overview covers the follwoing subjects: MiniMax and NegaMax Alpha-Beta search Aspiration search Transposition table ... Selective extensions The various search algorithms are illustrated in a compact pseudo-C. The

From "Endgame" [ 2.2MB mpeg ] an automatic animation of human motion. Used with permission. Robotics Laboratory , Computer Science Department, Stanford University. Ancient history Chess and computers go back a long way, perhaps because both appeal to rule-intensive, highly logical minds. In 1950, Claude Shannon, a scientist at Bell Laboratories, published the article that spawned the field of computer chess. (For a technical but complete history, see "Kasparov versus Deep Blue" in the bibliography. Shannon outlined how any chess computer would have to evaluate and choose future positions. He also gave some suggestions about how far into the future it would have to search a key consideration given the extremely limited talents of the early computers and the fiendish complexity of chess. By that we mean this: In the middle of a game, when many pieces remain in play, each player typically has 30 or 40 moves. So after one move by each player (that's called two "plies," or one "move") the board could show about 1,000 positions. By another complete move, there would be 1 million, and by the third move, 1 billion. That kind of "combinatorial explosion" lead to this phenomenal analysis: that the number of possible unique chess games equals 10 Must we mention this is an embarrassingly big number? Let's write it out:

Next: 14.3.1 Sequential Computer Chess Up: 14 Asynchronous Applications Previous: 14.2.4 Performance Analysis 14.3 Computer Chess As this book shows, distributed-memory, multiple-instruction stream (MIMD) computers are successful in performing a large class of scientific computations. As discussed in Section and the earlier chapters, these synchronous and loosely synchronous problems tend to have regular, homogeneous data sets and the algorithms are usually ``crystalline'' in nature. Recognizing this, C P explored a set of algorithms which had irregular structure (as in Chapter ) and asynchronous execution. At the start of this study, we were very unclear as to what parallel performance to expect. In fact, we achieved good speedup even in these hard problems. Thus, as an attempt to explore a part of this interesting, poorly understood region in algorithm space, we implemented chess on an nCUBE-1 hypercube. Besides being a fascinating field of study in its own right, computer chess is an interesting challenge for parallel computers because: It is not clear how much parallelism is actually available-the important method of alpha-beta pruning conflicts with parallelism.

The program dubbed "Shredder" running on a dual-2.7GHZ G5 piloted by Stefan Meyer-Kahlen managed to take first place. Competitors had to play nine rounds in three days with a time limit of 90 minutes per game for each side. "Shredder" was in second place after the first day and swept in to take first by day two with 5.5 points out of 6 games. Stefan wrote "The Macintosh version of Shredder performed very well and as far as I know this was the first time that a chess program running on an Apple Macintosh computer has won a major computer chess tournament. The Macintosh hardware has also proved that it is very competitive and fast." Updates on "Shredder" are also available.

58. An Introduction To Computer Chess computer chess may give a down to earth perspective on what is and is not In 1950, the first computer chess program was written by Alan Turing, http://db.uwaterloo.ca/~alopez-o/divulge/chimp.html

Computer Chess: Past to Present alopez-o@neumann.uwaterloo.ca UPDATE Introduction In this time of ``intelligent'' cameras, electronic games and coffee-makers it seems strange that at some point many computer scientists thought that computers would never be able to perform nontrivial tasks. Even today, many people are still unaware of what computers can and cannot do. It is sometimes amusing to see a scientist's face light up surprise when shown some computer tools that have been available for over a decade (like computer graphics, symbolic mathematics, etc), and their disillusionment when told that computers still can't efficiently perform some apparently simple tasks (simple for a computer) like finding the optimal route to be followed by a courier delivering packages all over the city. The history of computer chess is plagued by similar under-and-overstatements put forward by laypeople and experts alike. Though chess is an ideal problem for computers to attack. Its aims are clearly defined (to play good chess) and its advancement can be easily measured (player ranking). Computer chess may give a down to earth perspective on what is and is not currently possible with a computer and how much effort it may take to achieve an specific goal in computer development.

Science Search this site In this section Do not pass Go Computers can beat the world's best chess players but have yet to master other classic games like Go, writes David Levy Thursday October 24, 2002 The Guardian Ever since Garry Kasparov's sensational 1997 loss to the IBM chess monster Deep Blue, the chess world has thirsted for revenge. But the first opportunity ended in failure in Bahrain on Saturday, when Kasparov's former pupil and successor as World Champion, Vladimir Kramnik, could only draw an 8-game match against one of the world's leading chess engines, Fritz. But this was just the latest in a long series of human versus computer encounters that illustrate the inexorable march of artificial intelligence (AI). It's a story that began at a Dartmouth University conference in 1956, when several of the founding fathers of AI defined the goals of that infant science. One of them was to create a computer program that could defeat the world chess champion. Success would, those scientists believed, reach to the very core of human intellectual endeavour.

60. Computer Go Vs. Computer Chess Why is computer Go hard, why is computer chess easy? The real stumbling block inGo is developing a workable set of heristics to model the playing process. http://www.andromeda.com/people/ddyer/go/chess-vs-go.html

Computer Go vs. Computer Chess Why is computer Go hard, why is computer Chess easy? The real stumbling block in Go is developing a workable set of heristics to model the playing process. However, this is the problem because it's a given that brute force is out of the question. In chess programs, brute force is the only strategically or tactically significant factor in playing strength. The cleverness in chess programs is 95% directed toward doing brute force searches more efficiently. This *does* involve significant knowledge about chess, but in the end the knowledge is used mainly to order the search tree more efficiently. If the knowledge is faulty, the bad effect is that the search becomes less efficient. The moves chess programs ultimately make are almost completely dominated by counting the wood at the bottom of the search tree. In effect, the search is used to distill the rough knowledge into high potency play. On the other hand, in go programs the knowledge is all there is, because the search is impossible; so every little flaw in the the playing heuristics remains a visible flaw in the program. comments/suggestions to: ddyer@real -me.net
