Returning to the original subject ...

Quote from: Overtom on May 12, 2007, 04:39AM   

As I wrote before, eBay never responded to my complaint about the misleading content of the advertisement. So I left feedback saying "Wrong description!! Item was descrbed as chess/sudoku computer. It is neither!!"

Two days ago, eBay wrote me a message (in Dutch) which meant:

"Ceo1shop has filed an application for mutual withdrawal of feedback. Members are allowed to withdraw feedback if both agree that the feedback is no longer applicable."

Since this seller daily continues posting ads with the same misleading text, I wrote a message to ceo1shop with the following content:

"I received a request to cancel my feedback for this object. However, this object was advertized as a chess computer. I was told by several members of http://users.boardnation.com/~chesscomputers/index.php?board=1 that they thought this might be a chess computer. Daily you add new computers to eBay with the same misleading description. You can hardly expect me to retract my feedback if you go on putting this object on eBay with false descriptions."

So far, I did not receive any response, but if I will, I'll keep you posted ...

After eleven days I received the following message from ceo1shop@uxcell.com.hk

"Thank you for your reminder and we will pass this piece of
information to our
in-charge colleagues.  Thank you.

Best regards
Ceo1shop"


Very decent of them to pass it on to their "in-charge colleagues" ... but the so-called chess/sudoku computer is still being offered at eBay!!

With curiouser and curiouser regards,

tom

Nick,

I don't know if you're very much looking forward to playing all the games yourself.

Otherwise other members, who have some spare time on their hand, might consider playing a few games for the tournament.

Personally, I wouldn't mind playing a few games.

With best regards,

tom


Tom:
I like your suggestion and offer to help !!    I have made a couple of slots available by taking out a couple of fringe machines that could play later in a U1600 tournament.

I will post the current groups line-ups as well as current available slots.

Tom and and anyone else who is interested let me know what you think after you see the groups 

Thanks

Nick

OK Nick, now that you have well advertised your tournament, everybody here is looking forward the results...
But in the mean time, can you share the list of the computers which play this tournament ?

Of course, a web page updated weekly would be great  but I understand that it can take some time do build and publish (I have a french software that can be used for that, it is used in almost all tournaments in France and I used it for 
a tournament I played with my machines a few years ago

Best regards,

ALain:
Thanks for your input and link !!  A web page has crossed my mind al lot lately but as you said that also takes time to build.  A weekly update of course as well as a simple fast web page is possible

Your english is very easy to read and very easy to understand  and much better than my french.

Thanks for the additional info.  Before I play the Boris machines I will time them as you suggested and let you know the outcome.  This would be interesting to know and compare to see if my Boris machines timers run at the same speed as yours.

Seriously let us know the list of the machines and the results

Hi Turboking
I can see the smiley behind your first comment but still it does bring up some reservations which I have had since I started the tournament about if I should post details or not.

I know that Tom has a genuine appreciation and love for the low end ELO machines and I also see that Dan has a great love for his Boris Collection.  There are many fantastic collectors of low end ELO machines who visit this site.

There is history behind many of these machines.

So anyway my concern was that people who happen to read the results would avoid these machines and that is not what I am trying to show by playing this tournament.

It was mentioned earlier that there is a serious lack of information on low ELO machines.  I recognise that and since I happen to have a few oldies and newer ones that fit into that category I have the urge to play them and enjoy them and categorize them.  But not avoid them 

I had planned when finished to provide the information to Schachinfo to help by adding additional information in their already great database of games and machines.

Because I am competitive, I do plan to name one the champion and one the the baddest    But this is only meant to be as fun and not to detract or increase the perceived value or the beauty of a machine 

After all once the top machines step into U1600 they are just as likely to be knocked out immediately !

Anyway thanks for your "tongue in cheek" comment which I do appreciate since it allows me to mention my reservation.

All the history of computer chess starts at U1400 and I do not want to detract.  Unfortunatley most of that history has been lost over the years also with regards to info on game tests etc

Take care and all the best

Nick

ps when I posted the game and comments about the LJ-676 I actually just wanted to defend this poor machine a little

Hello Nick , I am happy to be a little part of your huge project... The thing that I said, it is that each Boris has his own clock speed. However, better means of adjusting the clock, it is to make run the Boris clock and to time it with your watch or a chronometer to see how much a truth 30 seconds is equivalent in Boris standardized time units.

You will see that the standardized time units are not equivalent to real seconds. Try for 1, 2 minutes or more the difference will be more evident. Perhaps that for only 30 second that will be not significant.

On my benchtest machine, if you want to give Boris 1 real minute, you must set it for 63 standardized time units because the clock of this specific Boris is slower than a real clock.  But for my Boris Master, it is the opposite; I must give him less time because his internal clock is faster than a real clock.

Anyway, really I don’t want to bother you with details… Just inform you with a bit of humour!

And sorry for my English, if I'm not clear, I’m so better in French. Good luck in your project!

Best regard. Dan.

Then it is necessary to be certain to give 30 seconds to Diplomat because it really needs it...

Certain Boris have faster and others slower clock. For example, on my benchtest machine, I must add 3 - 4 standardized time units per minute to be equivalent to 1 true minute.

Finally, I am very interested to know the whole tournament result. But I am obviously interested to know the classification of Boris Diplomat. Thank you.


Dan:
I am very happy to set the clocks correctly for a good comparison as per your suggestions.  Especially since I know this is of interest to you.

Can you confirm that you are asking that I set the levels as follows:

Boris Diplomat = 32 display units/move
Boris = 32 display units/move

If I have misread your comments then please let me know your suggested settings.

All the best
Nick

Hello Nick, I congratulate you and I encourage you in your titanic work! But as a Boris defender… I would like to remind you that as I say it on my site: I could validate that on all the Boris I have, no clock turns at the same speed. On this subject, it is mentioned in the Boris Diplomat's instruction manual: "Note that BORIS Diplomat’s timer is not designed as an accurate timepiece, but will chronicle standardized time units for comparative play"

Then it is necessary to be certain to give 30 seconds to Diplomat because it really needs it...

Certain Boris have faster and others slower clock. For example, on my benchtest machine, I must add 3 - 4 standardized time units per minute to be equivalent to 1 true minute.

Finally, I am very interested to know the whole tournament result. But I am obviously interested to know the classification of Boris Diplomat. Thank you.

Tom & Dan:
Thanks for your interest in my low ELO machines tournament 

Yes it is 72 machines that are entered.  I grouped them into 8 groups of 9 machines.  Therefore each machine will get 16 matches.  Also since each machine gets to play 8 other machines after group play I should have a a good feel of the ELO ability of each machine.

The rules are 30sec/move with slight exception, if for example a machine plays 35 sec on a level I will accept that but not if the time difference is too big, then I will set to the next level down.  So some machines may have a a penalty, but since I want to have an idea of their abilities in 30sec/mov setting as a standard I can accept a penalty and I can blame the programmers for being stupid. After all it is my tournament therefore my rules 

Yes Boris is represented in Group F with brown Boris Diplomat and Group G with Boris.

So the initial Group games are a total of 576.  Sofar I have played 280, therefore I am halfway through the group games.  After this you still have the knockout stage of the top 4 machines in each group playing 4 match knockouts until you have a champion.  So this will take me a while.

Once I have finished the group games I will post the group standings if you are interested and the games in pgn.  But that will take me probably another 3 months to finish the games.

If anyone is interested in the machines playing then let me know and I will start a new post with the details.

Also if anyone is interested in predicting the groups final order or the final champion then that would be fun to know and compare later when I finish all the games 

As you know this is a slow process, since you only play when you have the time and the mood to play.  So my goal is to finish U1400 this year.  If I can do that then maybe next year I start U1600.  And I will let the final 16 U1400 machines enter the U1600.  Which will give them the opportunity to show more if they can show more..and so on up the ELO ladder 

Anyway Rome was not built in a day. 

ps.. Dan your website shows a lot of care and attention.

best regards

Nick

Hi Nick,

Do I understand it correctly that you are holding a huge tournament involving 72 (sic!) weaker chess computers?

If you are, you're certainly doing work that may be quite relevant since it's mainly the stronger computers that have been tested for strength. The weaker ones have often been grossly ignored.

Needless to say I'm very curious to learn the results and wouldn't mind seeing them here in due course.

With best regards,

tom

Well I can say that China Backlit for all its faults including not knowing how to castle at least knows a checkmate when it sees one 

I am currently in the middle of a 72 machine Under 1400 ELO tournament at 30sec/move settings.  (I know torture but I am interested in finding out which machines play good and which machines play bad below 1400 ELO)  So anyway you can imagine my surprise when I witnessed this game:

[Event "2007 Under 1400 Active Chess Cup"]
[Site "Group D - 30 sec/move"]
[Date "2007.04.06"]
[Round "12"]
[White "Saitek Kasparov Chess Shadow, LV 4."]
[Black "Lang China Backlit Touchscreen, LV 4."]
[Result "0-1"]
[ECO "D20"]
[WhiteElo "1360"]
[BlackElo "1000"]
[PlyCount "90"]
[EventType "tourn"]
[EventRounds "16"]
[EventCountry "USA"]

1. d4 d5 2. c4 dxc4 3. e3 Be6 4. Na3 c3 5. Ne2 cxb2 6. Bxb2 Nc6 7. Nb5 Nf6 8.
Nf4 Bd5 9. Bd3 e6 10. O-O Bd6 11. Nxd6+ Qxd6 12. Nxd5 exd5 13. Rb1 Kd8 14. Bc3
Rb8 15. Qc2 a5 16. Rfc1 h5 17. Rb5 Qa3 18. Qd2 a4 19. Rcb1 b6 20. Qb2 Qd6 21.
Qc2 a3 22. Bf5 Re8 23. Qb3 Rb7 24. Rc1 Ke7 25. h3 Kf8 26. h4 Re7 27. Kh1 Rb8
28. Bb2 axb2 29. Qxb2 Rbe8 30. Qc3 g6 31. Qxc6 gxf5 32. Qxd6 cxd6 33. Rxb6 Ne4
34. f3 Nf2+ 35. Kg1 Nd3 36. Rc2 Rxe3 37. Rxd6 Nf4 38. Kh1 Ke7 39. Rh6 f6 40. a4
Ke6 41. Rc6+ Kd7 42. Rcxf6 Re1+ 43. Kh2 R1e2 44. Rxf5 Rxg2+ 45. Kh1 Re1# 0-1

In group play it currently has 3.1/2 points out of 14 so therefore the title of worst chess computer playing game ever made will probably not go to LJ-676 

The Chess Shadow is handicapped in this tournament because it does not have a 30 second move setting.  But still that does not give it an excuse to lose to the LJ-676 

The Chess Shadow is currently at 7.5 points from 14 games.  Not bad considering at level 4 it plays at 15 seconds.  Level 5 plays at 1 minute (I think) so for this tournament it is not an acceptable setting for me.

Anyway for me the title of worst playing chess computer will not go to the LJ-676 

best regards

Hi Ismenio,

Quote from: Ismenio on May 15, 2007, 03:00PM   

... in the scenario I was thinking about, not having a validation procedure is a plus since you would be able to demonstrate how computers like the CC1 make those "exotic" moves

I'm afraid you're overestimating the applet - which once again shows your positive mentality. But I'm afraid the applet can do less than you attribute to it.



With move 23. ... Ra5, the program will check all the squares from which a rook can move to a5. But since this is an illegal move, the program will never find this square (it only considers the legal squares). So things just go wrong in the program and it will malfunction.

With best regards,

Hi Ismenio,

Ceo1shop (or Uxcell?) is quite a large seller. I fail to see why eBay allows him to sell goods with false descriptions. It must be the fact that he sells about a thousand objects per month (and offers even more).

But I must confess that I already suspected this was not a chess computer. But I would never know if I didn't give it a try, would I? After all, this seller rarely responds to queries. This experiment cost me no more than 16 US dollars, which I consider cheap for finding out the truth.

I don't possess enough technical expertise to judge why the LJ-676 makes illegal moves. Maybe a faulty circuit, or a programming mistake. Who shall say? It is a small miracle that they can sell a back-lit touch-screen handheld at that price, even with no chess program in it at all



As to your question about the Java applet, it interprets the 'short' notation. So, for instance, in the case of 'Ra5', it will check all the squares from which a rook can move to a5 and if it finds a rook on any of these squares, it 'knows' where the rook came from. There are no validation routines, so if you submit a game the applet doesn't understand, it will just malfunction. After all, the applet was made in less than a week (based on an applet I'd made before but had never finished - http://overtom.nl/EngTomChess.html) I agree this is not the way to build decent programs, but the applet was only meant to be used by myself.

With best regards,

tom

Hi Tom,

Thank you for keeping us in the loop on this and for the great service you're providing us.

Also, kudos to you for the kind, yet firm, manner you're dealing with this fellow. That seems to be a nice facet of your personality.

Believe me or not, I actually liked the LJ-676 Chess :-
It must be the kid in this old and silly guy who likes pretty much anything that is small and has an LCD on it

Interestingly how in this day and age someone actually produces a computer that makes illegal moves!
That raises a question: does the Javascript kit you use to have us replay your nice test games handle that?
That is, will it play an illegal move if you have it on the list or will it validate it and give you an error?

Best regards,

Ismenio
