Strelka 2.0 B running for the IPON ...

[IWB]

... as usuall at http://www.inwoba.de

This one has to be explained a little more:
It seems that Strelka is not a Rybka-clone but much more a legal Fruit derivate (Source available, even if not mentioning the real source in the download)). I included the engine aprox. 2 years ago, but deleted it later because I wanted to post my list at some forums and was not allowed to do so with Strelka in it. In short: I was not secure enough about the whole thing. To be more decisive this time and a little bit as an apology to Jury Osipov I am catching up now (Better late than never!)

Do not expect miracles and do not compare it to close to other enigines in my list. It might have complet different opponents!

Is Strelka GPL?

Is Strelka GPL?

Miguel

Not really, but it has the source code with it while others dont have even that.
But may I quote Fabien: "Strelka did not look like a problem because I assumed it was free." (And he is right, even WITH source - others do not have anything delivered with it!)

Who am I to disagree with the original author

Btw: I wrote it already here, GPL is dead, at least for comp chess, as it is impossible to finaly prove something. Some might debate the legal issue but forget that everything is impossible to prove! For every expert you find someone who claims the opposite, just have a look in the current hot thread.

If Strelka is a Fruit derivative, it cannot be a legal one. I needs to be GPLed. To have the source open is not enough...

Sure you are 100% right, but again: Even the Fabien is not too much worried about it - why are you? (retorical)

You might stick to your legal aspect but actually to give the engine AND the source and to miss the "GPL" files and to mention where it comes from (what Osipov did in several fora in the past officialy - at least!) seems to be a minor glitch compared to other "infrigements".

I believe that the rights to Fruit were passed to Ryan Benitez. So his opinion is very important here.

I see many misconceptions around OS and GPL code. Since I am the author of chess open source code, sometimes I would like to get involve in those topics. Of course, this is a hypothetical case because the author of Fruit does not care about Strelka for other reasons, apparently. To have a GPL mandate over Strelka there should be code copied. He is not claiming Strelka has code from Fruit, why do you? (retorical).

It is rhetorical, I know, but actually I answered this in my first post here and to be more precise: I did!

I think the point about Strelka and many others is quite simple (from my point of view, although Miguel may agree): strong derivative engines filled the top of all existing rating tables. Today there are about 20 versions of ippo occupying the tops of the tables and therefore this "drop down" the other amateur engines (and also redirects the attention of the general public). This is very good for testers (better and better engines to test), but it is not "motivating" for authors who every day have 5 new +3100 ELO engines that move to their own engines more and more down on the table and away from almost all the valuable tests that run the testers (except CCRL, which tests engines throug all the range of ELO).
I addition, I have my reservations on how good it is to try 20 or 50 versions of virtually the same engine to detect after thousands of hours and computer "horse-power" that the performance of all derivatives is about the same +- 10 ELO in limited testing conditions.
