Turing engine
Is turing engine in any rating list, like ssdf? Has anybody tried it
against a wide variety of opponents to estimate its elo? Is there anywhere in the web more info about how it works? Thanks

Thanks Turing is much too weak of an engine to appear on the SSDF rating list. There are a couple of other testers who do include it in their lists. You can look at these links to get a general idea of its strength: http://www.grailmaster.com/misc/chess/comp/all.html http://loirechecs.chezalice.fr/ches...swar011PLs.htm The chessbase page that has the Turing download has an explanation of Turing. http://www.chessbase.com/download/download2.asp Tony

Try http://www.chessbase.com/download/index.asp and then select Engines from the drop down list and click the select program button. Tony

I realized quickly it is rather weak, but i didn't know it was so weak! There is some info on chessbase but i m still qurious about its actual algorithm

"Turing Engine" has another meaning. I suggest calling it "Alan Turing's Chess Program" or "TurboChamp." Nobody has tried it against other programs for the following reasons: [1] Alan Turing's Chess program has been lost to history. No copies survived. [2] Alan Turing's Chess program was written long before there existed any computer that could run it, So Turing ran it by hand using a pencil and paper, taking about half an hour to compute each move. [3] Alan Turing's Chess program was incredibly weak. There would be no point in playing it against even the weakest programs written for actual computers. Here is the only recorded game of Alan Turing's TurboChamp: Event "First game by the frst chess program"] [Site "Manchester, England"] [Date "1952"] [White "Turing's TurboChamp"] [Black "Alick Glennie"] [Result "01"] 1. e4 e5 2. Nc3 Nf6 3. d4 Bb4 4. Nf3 d6 5. Bd2 Nc6 6. d5 Nd4 7. h4 Bg4 8. a4 Nxf3+ 9. gxf3 Bh5 10. Bb5+ c6 11. dxc6 OO 12. cxb7 Rb8 13. Ba6 Qa5 14. Qe2 Nd7 15. Rg1 Nc5 16. Rg5 Bg6 17. Bb5 Nxb7 18. OOO Nc5 19. Bc6 Rfc8 20. Bd5 Bxc3 21. Bxc3 Qxa4 22. Kd2 Ne6 23. Rg4 Nd4 24. Qd3 Nb5 25. Bb3 Qa6 26. Bc4 Bh5 27. Rg3 Qa4 28. Bxb5 Qxb5 29. Qxd6 Rd8  Guy Macon http://www.guymacon.com/ HI Guy, all these are very interesting. I had no idea we lost it completely. Are you aware of any effort to reconstruct it? Or to make some valid educated guess about how it was working apart from the nondetailed info on chessbase? Thanks for the game Thanks

It's a Chessbase engine, written by Ken Thompson and Mathias Feist, that is an implementation of Turing's "famous paper machine". http://www.chessbase.com/download/index.asp Select Engines from the drop down list. Fascinating! It sure looks like Thompson and Feist had a copy of Turing's original program that other sources say was lost. I just went on a quest to ether find the program they started with or the source code to the program they wrote. I started with the description at the above URL: Turing Chess engine for Fritz by Mathias Feist and Ken Thompson which implements the famous paper machine by Alan Turing. The orginal set of rules was incomplete and unclear in several points, which are discussed below. 1. no mention was made of stalemate; detection was added with a positional evaluation of 0.0, which seemed to be the most logical. 2. a move gets a bonus if threatening mate in 1; a threat obviously means a nullmove for the other side which is illegal if the move was giving check. Still it may be a mate in 1 move. This was ignored, the move just gets the bonus for a checking move. 3. algorithm enhanced so that the engine may play with both sides, i.e. everything logically negated if black to move. 4. iterative deepening added to allow higher search depths. 5. a recapture is not made entirely clear: it is considered to be a capture to the same square as the previous move. 6. rule d) is not clear about checks/enemy pieces; a wKe1 and a wPe4 give the vulnerability of e2+e3, but a bPe4 gives an additional vulnerability of e4. Doesn't sound logical. 7. calculating the material value is impossible if one side is left with the king only. A division by zero would occur. In this case the material value is material+1.0 of the other side. The algorithm is based on material value, at the root moves with equal material values are resolved by positional values which are shown as the evaluation. This is not completely satisfying since the positional values are rather "jerky" and the more important material values are hidden. You download a setup program which allows you to install the engine in the Fritz directory. Download Turing Engine: http://www.chessbase.com/download/en...p%20turing.exe I downloaded it and ran it, and it created a single file called Turing.eng, dated 16092003 19:19 with a size of 139,264 bytes. Extracting various text strings from the above, I see: R6028  unable to initialize heap R6026  not enough space for stdio initialization R6017  unexpected multithread lock error R6002  floating point not loaded Microsoft Visual C++ Runtime Library Runtime Error! Program: ... program name unknown Chess32.dll Turing.eng Turing Mathias Feist & Ken Thompson .... So it's a Microsoft Visual C++ program with a Chess32.dll The obvious Google searches turned up nothing: Your search  Feist "turing.eng"  did not match any documents. Your search  Feist "turing.c"  did not match any documents. Your search  Feist "Chess32.dll"  did not match any documents. Your search  Feist "Chess32.c"  did not match any documents. Your search  turing "Chess engine for Fritz"  did not match any documents. So, does anyone have any other information on this algorithm  either the Turing or the Thompson and Feist version? Could someone with Fritz please run Turing.eng and tell me if it displays any other information (splash screen, copyright, help screens, etc.) and if possible post any that might help in my search?
