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
Re: [computer-go] Yet another article
MessageThe translation is not completly stupid (for an automatic translator). But its funny that it tries to translate English parts like the title of the first Chiptest/Deep Blue paper and mangles this completly. It fails to translate Austrian. E.g. bisserl (a little bit, ein wenig in German). These are the parts the German editors of my writings also want to translate to German. But on the same time it shows that the translator misses any minimal context knowlegde. E.g. Checkers is called in German Dame, which means also Lady. Lady is statistically the better guess, but in this context the lady programm Chinnok is of course completly stupid. The most funny translation is Fuer Fritz Programmierer Frans Morsch to For Fritz programmers fray to rotten. morsch means in German indeed rotten. But Frans is no valid word. As the name is written in uppercase the translation programm should have known that it can not mean rotten. I know no German language construct where one can write morsch in uppercase (besides at the beginning of a sentence). But upper/lowercase rules are in German extremly complicated. Constructs like Fritz Programmierer Frans Morsch are typical for my writing style. According my wife (she has studied linquistics) its a bad habit and not real German. The translator expected therefore some verbs. I do not now why Ed Schroeder is made to OD. Ed is also no German word. What does OD mean? Bayesion pattern matching is also tried in Go. I think the results are similar. There are some meaningfull game fragments reproduced, but overall it lacks any higher meaning. The approach also fails when the player deviates either on purpose (like in bisserl) or because he has learned bad style (e.g. Fritz Programmer Frans Morsch).

[computer-go] Most common 3x3 patterns
I've thrown together a rudimentary pattern extractor and was looking at 3x3 patterns taken from a collection of 9x9 games provided by Nici Schraudolph. Each game was played through in each of the four rotations and two reflections. Colors were inverted every other move, so all of these patterns have black to play in the center. Looking at the data below, it appears that: a) It might be better to somehow take into account the ratio between how often the pattern appeared and how often the corresponding move was played. b) Endgame moves appear often, because they get played sooner or later. c) Tesuji don't appear as often as one would hope. Connecting against a peep, making a bamboo joint, and the diagonal cut are not among the top patterns. Let the thread begin! The actual information: 134008 occurrences of ... .?. ... (Fair enough, you need a lot of these.) 9794 occurrences of ... .?. Bw. (And similarly for the other 7 transformations of this. Hane.) 7444 occurrences of ... .?. .w. (3 transformations.
