Hello Christian,

Hello Robert,

do you have any practical experiances with the Learn Function of the Diablo? Does it have consequences on the playing style if you switch it off?

Christian

Sorry, no; i always have "learning on" as it is the default-setting.

But I doubt, that "learning on" has any effect on the playing strength...

Hello Mike,

although i'm not Christian, i hope, that i may answer your question!

Quote from: Mike Watters on October 18, 2005, 05:40AM   


Sorry I have not experimented with it yet. I only know about it from the brief note in the manual.

Have you got the manual and/or know how to turn "Learn" on and off?

From the manual:

Learning can be en-/disabled with the "Interface"-button.

"SET LEVEL" - "INTERFACE"(Video) - "<-"(Training on) - "<-" (move flash 3) - "<-" (learn on) and then hitting the "NO"-button changes to learning off.

Now iam not sure about this Accoona computer but traditional chess computers (the ones with old fashioned circuit board and dusty microchips) all use an algorithm that is pretty straight forward cold and calculated. 
I can maybe understand storing past games or alternating algorithms to keep from playing the same line but how can they learn?, I just don't understand!, they can't save can they??. Based on the explanation on "how stuff works" It can't work. Calculating X moves into the game just contradicts the adaptation method. I guess the only thing it could do is adapt to the amount of time we as humans take. Most I played seem to play the same way every time on a particular level.

Mike,

I've got the whole package, Manual, Adapter, everything.
But I received the computer two or three days before my departure, and I could only test wheather it works.
I left it in Germany with a fellow collector...I do not know when I will see this beautiful machine again

Thanks to Ismenio  I have a Novag Diablo on which you can turn a Learn feature on or off. With Learn on the Diablo remembers positions from games in which its evaluation suddenly dropped. In future games it will try to avoid the same move.

This might be a dumb question but are any of the computers discussed here capable of learning form the games played?


The Fidelity AG #2-11 are capable of learning

Accoona does seem to learn.  I played the simple Fried Liver as white and won in about 20 moves.  I tried the same opening several hours later and the program completely avoided the line it lost with earlier.

That is a great question and modern chess computers should have this feature. I know Resurrection also "learns" while it plays right? But I wonder about one that would remember past games stored in an EPROM.

Not dedicated chess computer but I just remembered that the folks at Acoona did mention that their engine does learn and stores knowledge of previous games:

Not a dumb question at all Luckster.

I think that several types of chess computer have some sort of learning facility.

Thanks to Ismenio  I have a Novag Diablo on which you can turn a Learn feature on or off. With Learn on the Diablo remembers positions from games in which its evaluation suddenly dropped. In future games it will try to avoid the same move. The Novag Star Sapphire also has a learn feature.

Ah yes, and the function keys on the machine are all labelled in English. A bit strange for East Germany in the middle of the Cold War?

I see you have your wish on the Phantom 6100 now. Burned? I don't think so. 

Looking at the Ebay pictures Dick did you notice anything linguistically remarkable about the Chess Master Diamond?

Please keep the educational threads coming Ismenio.

All the best
Mike


Well, I was a bit surprised at all of the English used on the labels that were pictured.

That Phantom 6100 wasn't the only time I have bid and then asked questions, only to get the wrong answers, in my long eBay career.  Sometimes I have, unfortunately, won the item.  I remember the time I saw a pair of smoked taillights for my BMW 740, and the auction only had a few minutes remaining.  They looked nice and I wanted to change the look of the car, so I bid, never noticing that I was the first, and as it turned out, only bidder.

When they arrived, I discovered that they were simply stock taillights that had been painted, rather badly, black!    I spent a couple of hundred dollars on those things, and I still have them displayed in my basement, as a constant reminder to never bid at the last minute without reading between the lines of the auction wording.

Yeah right! I've seen how fast you and Dick are on eBay
For anyone handling your level of bidding skills this stuff is piece of cake!

Ismenio


When it comes to spending money, I am among the best.  However, my reading comprehension skills are not always very good on these eBay ads.  I have been known to bid first and ask questions later, and get burned.

Ismenio, this thread is too difficult for Dick and I.

I thought I would just share that with you. 




LOL!!

Thanks for checking out that link first, Mike.  My forte is looking at pictures, anyway.

I really the site howstuffworks.com because they explain things in simple terms with visual aids and fun facts.

They have an article about how chess computers work that's worth reading:
