Finding clones...

Post by Alexander Schmidt »

OK, new try, without anything that could make one believe I accuse someone. I think this one should be fine with the CCC rules.

Please read it completely and try to understand my points before you answer me and say I malign one.

Some of you will remember, I was involved in several clone discoveries, Patriot, Fafis, Deep<9>, xyclops, Nr.9, Christine, Lion just to name a few. In the past all of my discoveries turned out to be correct. So be sure I know what I am talking about.

First of all: What is a clone?

Fruit is released under the GPL, that means as soon as you copy a single line of Fruit to your own program, or if you start with Fruit and rewrite it, your program must be released under GPL too, even if you changed every single line. The only exception is if the original author agrees to close the sources. This is why one can never say that a clone is an illegal clone as long as the original author does not complain.

If you are interested in the cloning issue go on reading this carefully.

Beside the possibility to compare evaluation and PV lines you can look on the direct output of the engines, especially for UCI engines it shows some kind of fingerprint. UCI engines show the search information that you see in the GUI with so called "info strings".

An engine is free in how and when sending it's info strings and so it results in very different output.

Look at the following output of some engines, all done in the starting position for a few seconds, most until depth 9-10. I start in alphabetical order of my UCI engine collection without own book so you cant say I only show special engines. Then a few of the good engines follow. Try it yourself if you like, the best is to use Arenas debug window. Be sure to uncheck "Only Information with PV".

Do not look on pv lines, evaluation and so on. Look how the output looks in general, when which info string appears. which info strings are in a line, which stand alone. Some appear later when a higher depth is reached.

Look on the appearence of the first engines to get an imagination how different the output of engines is, and read my notes and take a closer look on the last 3 engines.

Now you have seen some engineoutput, and you know how it looks like. Now to Fruit, it is comletely different to the above ones.

The position of the info strings for every depth is:

depth
depth - seldepth - score cp - time - nodes - pv
depth - seldepth - time - nodes - nps

Later it looks like this:

currmove - currmovenumber 19
currmove - currmovenumber 20
depth (x) - seldepth - time - nodes nps
depth (x+1)
currmove - currmovenumber 1
time - nodes - nps - cpuload
hashfull
depth (x+1) seldepth - score cp - time - nodes - pv
currmove - currmovenumber 2
currmove - currmovenumber 3

And now to Rybka 1.0 Beta.

The position of the info strings for every depth is:

depth
depth - score cp - time - nodes - nps - pv
depth - time - nodes - nps

Remember Fruit:

depth
depth - seldepth - score cp - time - nodes - pv
depth - seldepth - time - nodes - nps

The only difference is Rybka don't give seldepth infos and has added nps in 2nd line.

And later the output changes to this:

currmove - currmovenumber 19
currmove - currmovenumber 20
depth (x)- time - nodes - nps
depth (x+1)
currmove - currmovenumber 1
depth (x+1) - score cp - time - nodes - nps - pv -
currmove - currmovenumber 2
currmove - currmovenumber 3

Remember Fruit:

currmove - currmovenumber 19
currmove - currmovenumber 20
depth (x) - seldepth - time - nodes nps
depth (+1)
currmove - currmovenumber 1
time - nodes - nps - cpuload
hashfull
depth (+1) - seldepth - score cp - time - nodes - pv
currmove - currmovenumber 2
currmove - currmovenumber 3

Again nearly the same with some missing info strings in Rybka.

OK, at last again one output of a completely different engine, if I remember right, it was Rybka 1.6.1, last private version before Rybka 1.0 Beta appeared. I don't have to mention that it was weaker by hundrets of ELO's. I did not get it, I just got the debug output of one who got it by Vas.

I must admit it would be possible that one just tries to copy the engineoutput. Just, it makes no sense at all. It depends on the whole structure of an engine and when I asked Vas about the similaries he said, he did not take Fruits output as an example.

And not to forget, all this similaries could be coincidence :lol:

Similarities in I/O structures (as opposed to actual PV's and scores) prove nothing at all.

To talk meaningfully of cloning an engine requires to show identicalities in engine source code and data - not trivial I/O mechanisms.

A programmer may well copy output deliberately (by copy I mean have his program produce output in the same structure as a target program) in order to bug test and compare development progress. If target program XYZ is deemed to be bug-free and able to play chess, then paralleling its output is a reasonably effective method of ensuring one's own program to be bug free and playing chess also.

Sorry, but this makes no sense to me.

Of course I cannot proove what Vas told me, but I know it for myself, so...

However, if one specifically claims "I did not look at the UCI output for program X" but upon analysis the output exactly matches program X, isn't that a bit more of a coincidence than one would think possible?

Well, if the report of Vas's comment (did not look at Fruit UCI output) is true, you have two possibilities

The comment itself is true, in which case the matches are perhaps curious.

The comment is false, in which case he quite reasonably used Fruit as a development target.

I would prefer to imagine he fibbed over which engines he concentrated his firepower on rather than the alternative assumption that he copied code. It's not entirely unimaginable he might have wanted to keep quiet over his development procedures and targets, is it not?

The word clone is inappropriate and should not be used

Post by tiger »

Alex your analysis is very interesting.

However I believe that the word "clone" in the title of your message could be misleading and the discussion could degenerate because of this.

You are comparing Fruit 2.1 and Rybka 1.0 outputs, and I think that nobody who has seriously compared the two programs could say that they are clones.

Rybka is clearly not a clone of Fruit, so the word "clone" in your message title is not going to help looking at the matter in an objective way.

I wanted to point out this because in earlier discussions where I was talking about the similarities between Fruit and Rybka, people immediately thought I was bringing back a CLONE accusation.

Actually, what I believe is that Rybka 1.0 started its life as Fruit 2.1. I mean that at some time T=0, probably in the middle of 2005, the source code of Fruit has been taken as the base and has been little by little modified until it became Rybka 1.0 as we know it.

Siginficant and brilliant additions have been made to that code. The end result is a program that is much stronger than the original program.

So in my opinion:
- Rybka 1.0 is not a clone of Fruit 2.1, it is somehow different and better
- Rybka 1.0 started as the source code of Fruit 2.1

I think your analysis tends to confirm this opinion. It is a piece of the puzzle. Of course more analysis, in particular of the sources codes, is necessary to confirm it completely.

We have a different opinion what clone means. Starting with the source code would violate the GPL even if every single line is changed. So I would call this cloneing.

But as I stated several times before, it must not be illegal in case the original author agrees.
