ALSO MORE THAN ESTIMATED NUMBER OF TOTAL WORDS SPOKEN BY MAN SINCE THE BEGINNING OF MANKIND, YES THIS INCLUDES ALL THOSE WORDS SPOKEN BY WOMEN TOO . HA HA !!! This info in book stated that a computer came up with this number ! yours BBG |
| Posted by jean-marc uskidscompute.com 5/23/2003 00:16:14 Play online chess | Calculation... Message: Sorry if I'm teaching you how to suck eggs, in case you already now... The result is simply the factor of multiplying the number of possible moves available at each ply. With a simple coin, after three tosses (heads or tails) you get 2x2x2 = 6 different results. In chess say white has 20 (I'm guessing 16 pawn and 4 knight moves) first move options and black 20 responses you get 400 possible games at the end of the fist move. Imagine how rapidly that grows as more options become available. The number of possible games would increase exponentially. All you have to do is count the number of possible moves in each position. How did they do that ? I give up ! How ? Professor Jean-Marc PS: I was never this smart at school ! ——— Magnus Carlsen Survives on His Wits — One of the reasons that Garry Kasparov was the world’s dominant chess player from the late 1980s through the ’90s was that he was better prepared than his competitors. He spent an enormous amount of time researching chess openings for new ideas to spring on his opponents, or he paid others to do it for him. Magnus Carlsen, currently the world’s top-ranked chess player, is beginning to be as dominant as Kasparov was, but it is not because of his preparation. He has described himself as a bit lazy, and so rather than play the most popular chess openings, which everyone has studied, he often chooses systems, particularly as White, that do not yield any advantage. Carlsen wants to ... |
| Posted by sumsar uskidscompute.com 5/23/2003 00:47:31 Play online chess | Just count! Message: They have just counted them like you did for the first move. Honestly I think they programed a computer to know the rules of chess and the it did it for them. Just took every piece in every possition from the first move then added all the moves and so on. If you give a strong enough computer enough time it will in the end come up with an answer. The same will you, just try! Sumsar ——— Impressive Field at World Open — The World Open, the annual chess tournament in Philadelphia that always takes place around July 4th, often lives up to its name by attracting a world-class contingent of chess players. This year is no different as the field includes Francisco Vallejo Pons of Spain, Surya Shekhar Ganguly of India, Loek Van Wely of the Netherlands, Luke McShane of England, Evgeny Najer of Russia, Viktor Laznicka of the Czech Republic and Ilya Smirin of Israel. It also includes many of the best Americans, among them Gata Kamsky, the United States chess champion, and Alexander Onischuk. The players come because the tournament offers one of the biggest prize funds in the world. This year’s is ... |

LOL. ——— Magnus Carlsen closes in on Garry Kasparov's record chess rating — Magnus Carlsen is closing in fast on Garry Kasparov's all-time record chess rating. The 19-year-old Norwegian scored an unbeaten 7.5/10 at Medias, Romania to take his score on the daily calculations up to 2826, just 25 points shy of the great Russian's peak mark. And Carlsen did it while still not in optimum form. He began with two draws, then took risks including a 1 e4 e5 2 f4 King's Gambit and a couple of dubious positions, but his inventiveness and will to win coupled with the growing Carlsen-fear of those on the other side of the chess board ensured another impressive outcome. Technically his most interesting game, certainly from the practical viewpoint of competition ... |
| Posted by raimon uskidscompute.com 5/23/2003 01:01:19 Play online chess | Thanks - fascinating Message: it'll give me something to think about before I start my next game! ——— A Race for Second at the Grand Prix — With four rounds left in the Fourth Women’s Chess Grand Prix in Jermuk, Russia, time is rapidly running out for anyone to try to overtake Nana Dzagnidze of the Republic of Georgia for first place. She leads by 1.5 points over Lilit Mkrtchian of Armenia and Tatiana Kosintseva of Russia. She still has to play Mkrtchian and Hou Yifan of China, the chess tournament’s top seed, who is currently in fourth, so there is still a chance she might be caught. But her form so far has been superb as she has only yielded one draw in seven rounds. So the rest of the tournament may be a race for second. The Grand Prix is a series of six tournaments organized by the World Chess Federation. The winner will ... |
| Posted by atrifix uskidscompute.com 5/23/2003 01:31:25 Play online chess | Message: Any decent computer will be able to total up the number of positions after 20 ply (half-moves) from the initial position and tell you how many nodes it has searched. You can try it yourself with a copy of Fritz or Chessmaster if you leave it on for awhile (expect a few hours). The estimations for deeper numbers of positions, like up to move 40 or 60, requires a different sort of calculation. I don't remember exactly how these numbers were estimated, but I imagine you could fairly easily find the calculations, or maybe someone here knows. ——— A White Day at the Women’s Chess Grand Prix — Everyone knows that playing White is an advantage in chess (though curiously it was not during the last round of the King’s Tournament in Romania that ended Friday; then Black won all the games). But, the results of Round 6 of the Women’s Chess Grand Prix in Jermuk, Russia, were still startling. White won every game. It was the second time in the first six rounds of the chess tournament that every game had ended decisively. Over all, only 8 of the 36 games in the tournament have ended in draws, an astonishingly low percentage. After six rounds, Nana Dzagnidze of the Republic of Georgia leads with 5.5 points, a point ahead of Lilit Mkrtchian of Armenia. Tatiana Kosintseva of Russia is ... |
| Posted by raimon uskidscompute.com 5/23/2003 02:09:08 Play online chess | Message: Can you tell these programs to simply count the positions rather than analyse? Or does this amount to the same thing? |
| Posted by zucan uskidscompute.com 5/23/2003 06:18:32 Play online chess | Computers and # positions Message: If you are using a computer engine, such as Fritz, to count the number of moves, it won't be the same number. Sure, it does tell you how many nodes it has searched, but that isn't an exhaustive number... after all, it probably pruned off tons of trees in its search based on the thought that it was a poor move and better ones already have been found. If you haven't turned off the opening book, that would affect the number too... Zucan |
| Posted by v_glorioso12 uskidscompute.com 5/23/2003 15:07:41 Play online chess | hey! Message: is that number the move order or total number of positions reached by a certain move order? like, is it that there is 1 way for the position reached when 1.Nf3 c5; 2.e4 d6 is played or is there 4 ways for the move order 1.Nf3 c5; 2.e4 d6 and another for 1.e4 c5; 2.Nf3 d6 and another one for 1.Nf3 d6; 2.e4 c5 and the last one for 1.e4 d6; 2.Nf3 c5? sry if it is confusing... :-S thanx |
| Posted by jean-marc uskidscompute.com 5/25/2003 18:04:47 Play online chess | Processing time... Message: I read somewhere that even if you took the strongest current computer in the world and asked it to count all the different possible moves in all the possible chess games, even if the computer had started at the time of the first man leaving the caverns, the computer would still be in the process of counting today. I assume that someone "averaged" the number of possible moves in the middle game in coming up with a number. Great question, though... |
