Speaking of false evidence...

[Dann Corbit]

Here are assembly listings created from the binaries of Strelka 1.0, Rybka 1.0 Beta, Fruit 2.1 using IdaPro freeware:
http://cap.connx.com/chess-engines/new- ... ompare.zip

It is interesting to note that the UCI parser of Rybka 1.0 definitely does not even call strtok().

We have been quibbling over false information. These so-called source code dumps are whimsical fabrications.

You can get IdaPro Freeware here:
http://www.hex-rays.com/idapro/idadownfreeware.htm

and repeat the experiment for yourselves. The UCI parsers of Fruit 2.1 and Rybka 1.0 are not terribly similar and Rybka clearly does not use strtok() at all.

I suggest that it will be a worthwhile exercise to perform the experiments yourselves and not rely on the words of someone else (including me!)

Dann, you are way too smart for this. You know good and well Bob is not the least bit interested in the truth. And they have taken this poor innocent kid, pumped him up, and sit back and shamelessly let his name be drug thru the mud. Im embarrassed for them all.


PS: Since my first day in computer chess, you and Jim Ablett are the 2 i have looked up to the most- you 2 are my heroes of sort.


Best,

Should be interesting to see how the accusers respond to this!

[Dann Corbit]

Should be interesting to see how the accusers respond to this!

I hope that they respond as follows:
1. Download the disassembly tools or use their favorite disassembler.
2. Disassemble the binaries themselves.
3. Examine the resulting listings carefully.
4. Form their own conclusions.

I will be genuinely interested in what they have to say if they actually perform these steps. I am not interested in discourse with anyone who has not done so, because they are running on hearsay evidence and evidence I believe to be largely fabricated.

I wonder if any of them have the guts to back down if they're proven wrong.

Exactly what world did you wake up in Graham- if it is the truth- which i am quite certain it is- they will ignore it and/or divert attention away from it. This was never a quest for truth- merely a witchhunt.

Sorry again Dann, but you are again wrong. It is there, without the function name.

Please Dann, if you are going to say that what I post is "whimsical fabrications", please investigate it a little more.

Should be interesting to see how the accusers respond to this!

I hope that they respond as follows:
1. Download the disassembly tools or use their favorite disassembler.
2. Disassemble the binaries themselves.
3. Examine the resulting listings carefully.
4. Form their own conclusions.

I will be genuinely interested in what they have to say if they actually perform these steps. I am not interested in discourse with anyone who has not done so, because they are running on hearsay evidence and evidence I believe to be largely fabricated.

I wonder if any of them have the guts to back down if they're proven wrong.

There you go- getting silly again.

Dont know about you- but if Dann Corbit tells me it is going to snow in the middle of August- im getting out my long johns, cover-alls and insulated boots

I am wrong often enough to make it a bad idea.

But whatever the case may be, it is always a good idea to keep the attitude for which the "Show-me" state of Missouri is famous.
