Humankind Makes Last Stand Against Machine

MrZeebo writes "According to this Financial Times story, Garry Kasparov has begun another match against a computer chess program on Sunday, this time playing against the Israeli-developed Deep Junior. Kasparov is the highest-rated chess player of all time, and lost to Deep Blue in 1997. According to the article, Deep Junior, despite evaluating less moves per minute than Deep Blue, is considered to be a superior chess player. The match will span 6 games, the last one being February 7th." Kasparov has won the first game.

      I disagree with you, since I could apply your reasoning and conclude that this is NOT Kasparov competing either. It is Kasparov's school teachers, nutritionists, chess instructors, fellow chess players, parents, programmers of software that Kasparov uses to train with, and authors of chess books that he no doubt assimilates knowledge from.

      My point is that computer algorithms aren't the only thing shaped by the contributions and knowledge of others.

      Both Kasparov and Deep Junior are "black boxes" with a recognized I/O protocol for playing chess. One box is made of meat and one is made of hardware/software. Neither box is created itself without huge amounts of guidance, programming, critiquing, iterative refinements, constant tweaking of strategies, etc.

      Yes, but what the computer can do is calculate the probability of all of Kasparov's moves, then only explore the options that are most probable. Although the computer cannot correctly predict the exact move Kasparov is going to make, it can probably narrow it down to 2 or 3 likely moves. It can pretty much ignore all the other moves, because Kasparov is not going to make a bad play. Kasparov's move is either going to be the best move for the situation, or at least the second or third best move. Although the 'best move' for any given chess scenario is debatable, the way the computer plays is to quantify the relative strengths of different positions and try to get into the strongest position.

    First of all, as long as we are winning one single game against the computer under tournament settings, we've got a chance. Karpov may have only drawn against deep fritz, but you know what? That means we have a chance: That draw includes some wins.

    Kasparov won some games before ultimately losing to Deep Blue in 97. Now he's already won one more in 2003.

    Chess is a game chosen by the AI to deceive you, because computers happen to be, today, really, really good at Chess. With judicious pruning, they have look-ahead trees of ten, fifteen, twenty, fifty moves. Folks, that means that except for some cute evaluation software to determine what lines to prune down, they're basically brute-forcing their way into winning.

    And they want us to bow before this brute force?

    Never!

    They can brute-force their way out of 56 bits, sure.

    But let's throw them against 128 bits.

    Let's throw them against Go.

    From "The Game of Go" by Matthew Macfadyen, page 122:
    (I'm typing this for you out of a book -- and first-strike claim fair use with +2 save for being anonymous).

    Computers and Go.

    Gary Kasparov's recent difficulty in handling computer opponents has been described as the fall of the last citadel in the battle of humans against the encroaching computer meance, but Go still stands as a refuge well beyond the reach of curent programmers. This is not for want of trying. The late Ing Chiang Ki from Taiwan sponsored an annual Go tournament for computers with good prize money, and several of the entrants put ijn years of work on their programs. But the tournament finishes with a challenge match between thew inner and a teenage human. This has to be played with a huge handicap - currently 14 free moves at the start of the game - and this is only diminishing slowly.
    Part of the reason for this is accidental. Although for a human brain Chess and Go present similar challenges, there is an easy way to see how well you are doing at Chess - just count the pieces on the board. Looking a few moves ahead and counting the balance of pieces hich results gives a quick and easy way to avoid silly moves. Chess computers only need to be clever at sorting out a small number of "sensible" alternatives.
    There is no such simple method in Go. Positions do not have a clear value until the game is finished, and the same pattern of stones may work perfectly in one context and be almost wrothless in another. One source of the great strategic trichness of Go is that you can choose between making large-scale loose formations and small-scale solid ones and each provides for different types of efficient development.
    There are certain types of localized position in which computers have been used to find the right moves by exhaustive analysis, but even for quite modest-sized problems the programs run into millions of varioations. This is simply not a practical approach to most Go positions. It comes as something of a relief to discover that methodical calculation, considering all the possible outcomes, is neither necessary nor very useful in Go.


    So. Let's concentrate on Go! In which the WORLD'S BEST computer program gets beaten - not by the world champion, but by a GIRL or BOY possibly still in highschool -- after being given more than ten moves to make without human response.

    Computers are toast, even at a simple game with only two rules, one of which is hardly ever used and is just a "hack" to make infinite loops impossible. Humph.

    Note: Another reason look-ahead-trees don't work for shit in Go is that at every point in the game, you can move to any free square. Typically, this means the first player has a choice of 361 squares for the first move, with the player making move 2 have 360, for move 3 there are 359, etc, with the only change in this pattern occuring when pieces are captured, pretty rare in professional games. (You just threaten to capture). So the "base" of the exponent is differnet AND you can't prune the look-ahead tree.
    Chess has been SOMEWHAT brute-forced. So what.
    Few things useful in the real world are as closed (8x8 board; clear general concept of positional value [number and location of important pieces]) as Chess.

    So don't let the AI tell you chess is the last stance. Go is.

    Not to be a spoilsport, but this is utterly impossible. For a computer to intentionally do harm to a human being through a chessboard, the computer would have to either be programmed with the knowledge that human beings are subvertable by electrocution via the output line (and therefore via the chessboard), or have inferred it from a deeper understanding of physiology. The chess program would have to be extensively meta programmed with thinking routines and structured information about the outside world, as "win at all costs" is a statement of intent, and we have not quite moved beyond where stated intent can only be a simplification of the programmer's desires when structuring routines. This, as I have said, is changing, but is very doubtful that any machine from 1993 can said to harbor a real "intent," and the self-coding capabilities to carry out that intent. The chessboard would also have to be wired in such a way as to have access to a dangerous degree of alternating current. As basically all computers and computer ports run on DC, and DC is harmless, they would have to wire a board directly to an AC power supply, and both moniter and control the flow of power by DC regulators connected the CPU. The person at the table would have to complete a circuit between some electrified part of the board and another or be sufficiently grounded while sitting at the chair, or power transmission would fail. The chess pieces would have to be entirely metal to facilitate this transmission.

    For that matter, they would have to connect the computer to a physical chessboard instead of just displaying one on the screen, or (more likely) having an IO person type in the human moves and moving the computer's pieces on the board. Commercial machines that can move / react to moves with a chessboard as IO, and with questionable AI, have been available since the mid-eighties. However, they are quite limited, hardly available, and physically incapable of electrocuting someone.

    Stranger things have not happened. Things that had been previously believed to be impossible through some misreading of logic have eventually come true, given time... Machines have advanced to the point where they now can play chess, a once "impossible" feat, but it was truly impossible that Wolfgang von Kempelen's Turk could play a meaningful game of chess in the 18th century. Anything is possible given enough time, but what you describe is impossible without both technology greatly in advance of what we have available today and an almost homicidal recklessness spanning far beyond accidental negligence on the part of the designers.

    As you describe it, this is truly impossible.

  31. Notes from the Kasparov-Junior match by migstradamus · · Score: 4, Informative
    Always interesting how much interest this man vs machine stuff can still generate. My name is Mig Greengard and I'm doing the official live web commentary on the Kasparov-Deep Junior match and worked with both Kasparov and one of the Junior progammers (Shay Bushinsky) for over three years as the director of Kasparov's now-defunct website.

    There was a good attendance and a great deal of media coverage today for game one, particularly considering it was a national holiday in the USA. (Well, almost.) Kasparov had the white pieces in game one, which is an advantage. (Interestingly, the Deep Junior team won the drawing of lots and could pick which color to have in game one (and 3 and 5), and chose to start with black.)

    He completely dominated the game, it was a total stomp. He played 'real' chess instead of the dubious anti-computer style he used against Deep Blue in the 1997 match. Anti-computer chess involves trying to reach positions that computers don't play well instead of just making what you think are the best moves. Deep Blue showed that computers are pretty much beyond being vulnerable to these tricks nowadays, although every once in a while you'll see a strong program play like an idiot in a position it doesn't understand.

    Kasparov prosecuted his advantage very quickly. In the press conference afterward he showed how much he had learned about playing computers. One key, he said, is that a computer doesn't understand results or practical chances, it only understands the evaluation of the current position. So instead of trying to swindle a way out of a bad position like a human Grandmaster would, by creating maximum chaos and hoping the other guy makes a mistake, a computer just tries to find the 'least-worst' move all the time. This is the only effective way for computers to play chess, but in inferior positions it often makes them look completely docile, if not pathetic.

    He won't be able to do this in all six games, of course, and he'll probably lose one just because a human can't play error-free chess for so long against a strong opponent and computers punish errors ruthlessly. But game one showed he's prepared to the gills, as usual, and along with the fact that he's the strongest player in history should give him a decisive edge.

    You can watch the games live with my commentary (and that of other commentators on-site as I relay their words) at many places on the web. Most of it is directed toward the level of the casual fan, not the chess expert. The company I'm working with, ChessBase, publishes Deep Junior and just about every other top chess program. (The program Fritz just drew an eight-game match against the world's #2 rated player and current world champion, Kramnik, in October 2001 in Bahrain. I was the webmaster and commentator on that match as well. I think I prefer the cold here at home in NY to the Bahraini humidity.)

    As for the Deep Blue versus the current micros debate, that will be eternal as long as Deep Blue is in pieces. It was obviously much more powerful, but that doesn't mean it was a better chessplayer. We only have six games as evidence of its strength. They were good, but they weren't godlike and Kasparov said at the opening press conference that when you go over those games with Deep Junior it's clear that it plays better in just about every moment. (Except for two, which are the moves Kasparov has always suspected were the result of human interference. But that's another kettle of conspiracy.) Deep Blue was far, far ahead of its competitors in 1997, but computer chess programming has not stood still for the past six years.

    It's also worth noting that what constitutes a huge advantage in computer-computer competition does not always translate into play against humans. A processing power advantage of just 10% between two identical programs will cause a lopsided score, but even a fourfold increase in processing power usually only means an extra 30-40 rating point gain against open competition. That is, one more win out of ten games.

    I've spoken with Deep Blue's architect and other members of the IBM team on several occasions. Their egos are almost as big as Garry's! Hsu's book on the building of Deep Blue is almost as partisan as Kasparov's comments. They are both very competetive people. Personally I don't think there was any human interference in the DB match, but IBM's secretive and heavy-handed behavior needlesssly created a great deal of circumstantial evidence and suspicion.

      Assuming this is the book you mean, I'd have to disagree. I read this over the holidays, and thought Hsu went out of his way to attempt to be impartial.

      He obviously had a vested interest (as do you), but I didn't feel his book was in any way partisan - he wanted to win, but he was perfectly capable of dealing with the inevitable losses. As he's one of the participants, you have to take the comments about Kasparov's behaviour with a pinch of salt: but that's a very minor part of the book, and perfectly understandable given that it was an "I said/they said" situation.

      It's a great book for finding out just how cobbled-together some of the early chess playing machines were - and that the kinds of problems they ran into along the way were incredibly mundane (fabrication problems, hardware failures, networks going down, last minute "this can't possibly hurt" changes to the code, etc). Although the book is pitched as being the story behind Deep Blue, a large chunk of it relates to the machines leading up to that point and the process by which Deep Blue came about (rather than that particular machine).

  33. He's right, you're retarded by jpmorgan · · Score: 4, Informative

    A chessboard is 8x8, meaning 64 spaces. However, each space can contain a pawn, a rook, a bishop, a knight, a king or a queen of either colour. The best estimate for the number of states the board can be in is 2.99x1041.

    A naive encoding is 96 bytes per state. Let's say a tighter, or compressed encoding is 48 bytes per state. So a rough estimate as to the total storage space it would require is 1.44x1043 bytes.

    In words, that's about 14 million billion billion gigabytes of data. I'm not going to say it'd be impossible to build such a storage mechanism in the forseable future, but I will say it's incredibly unlikely, and would be mindbogglingly expensive. And with modern technology, would require more matter than is actually on the planet. So no, dynamic programming wouldn't be useful in chess at all. Proving once again that if it were as simple as that, somebody would have thought of it already.

    Out of interest, consider Go. This is a board where dynamic programming really would be useless. With around 10750 possible states, it would require significantly more atoms than are actually in the entire universe.

  39. Competitive Magic the Gathering by Kid_Korrupt · · Score: 2, Interesting

    There seems to be some debate in this forum about the merits of computer chess players and their brute force method. Some posters have brought up go as a 'real' challenge for computers. Although I haven't played go I would like to bring up another alternative: Magic the Gathering.

    Now before I get scoffed at, and modded down I think the case for magic should be heard. And I am not talking about casual play with your latest dragon deck, but competitive magic. The WOTC and DCI support a fairly large, world wide, competitive player base, with prize support up to about $30,000. Now this doesn't compare to what chess masters can win but I find the similarities very interesting.

    The thing in my mind that makes magic far more interesting and challenging than chess is that the game changes every 4 months. Based on some essential fundamentals the actual rules recieve a complete overhaul, and even top players that cannot adapt to the new format will find themselves sharing tables with the scrubs.

    I think a real challenge for programmers would be able to make a program that could thrive in this type of environment. To me that would be true AI. Being able to actually LEARN and not brute force its way to a win would be an amazing accomplishment for AI programmers.

    The IBM guys changed Deep Blue's parameters half way through the competition, and it started playing differently that it did the last game. I understand that humans can do this too, but IIRC, they stated before the matches started that they would not do this.

    They did change the parameters. It is allowed under the rules, and common practice. If they ever stated "that they would not", please provide a citation.

    Also, they would not give Gasparov transcripts of the previous matches that Deep Blue had played.

    Accurate, but irrelevant since Deep Blue had played in no previous matches. DB's precursors *had* played in matches, and those transcripts are public record. If Kasparov didn't have them it was because he didn't look.

    The thing that GK complains so much about is that they refused to provide the evaluation logs. Big difference! The logs describe the *reasons* that DB played or rejected certain moves. Kasparov is no more entitled to them than any human player is to have his opponent sit down after the match and descript why he played each move. No professional player would ever give *or ask for* such a thing.

    Frankly, I think this is why IBM disassembled Deep Blue and will never sponsor or play in another such match. Kasparov poisoned the well. The payoff for IBM is in the public relations, and for GK to accuse them of cheating seriously detracts from the PR value. And there's no way to disprove the charges. (BTW, the match jury *was* given the logs, and after examing them they cleared the Deep Blue team of any wrongdoing.)
