DON 1.0b derivate Glaurung

[mcostalba]

Actually looking at initial commit:

[LINK deleted by mod Team]

It seems more Stockfish than Glaurung (for instance book and move generation implementations are almost directly copied form SF).

I'd think it shows "derived from Glaurung" simply because author copied SF readme file verbatim changing only the name:

https://github.com/mcostalba/Stockfish

Anyhow I have to add that the author did a good amount of work above the original sources so that it is a derived and independent engine by all means.

And because it publishes the sources it is 100% legal.

Marco Strongly agree.

I also seemed. Code very stockfish
In addition to these things to you that you love, is compiled as C + +11(Visual C++ 2012),
But it certainly has a lot of work that the author does not explain.
The branch compiled, is saying DON-mingw

Legal, but not really an example to follow. Acknowledging where things were taken from is, at least, a minimum standard of courtesy (to the authors and the users who download it or may start a fork from it). I understand that for certain piece of software is awkward to list all contributions, but here... he could have just added the name SF to Glaurung.

But did he actually release anything?

Just having a repository on github with some work in progress and a README that isn't yet very clear on the origin of the program seems fine to me. But if he's been publicly announcing his project somewhere then I agree he should have made it clear that it derives from SF.

So the question is how did Jose learn about this engine?

I've done an "extensive" google search and I'm 100% sure José's source is [LINK deleted by mod Team]. So now the question is whether "tyuyy" is Ehsan or not, I guess.

I work with who asked me to compile,
compile almost everything. It is a pleasure for me.
It's easy to find a program, you enter Github, and marks in the search "Chess" and you sort by last updated.

Now for my question is that you ask that question.
A respect for others members, please.

Thanks SilvianR.

Glad to hear that last Visual compiler supports XP.

After several hours of entertaining work.

Good news. And a big thanx to Jose for compiling!
So I will do a testrun for my LS-ratinglist, when the testrun of Stockfish 140129 is finished...If all works correctly, the result of Don 1.0b should go online next tuesday...if it is strong enough (at least 30% scoring against the engines of the LS-top10-tournament is necessary)...
In a little preview testrun on my old non-SSE-PC, the x64-DON is around 30-40% slower than Stockfish 140129 x64, but the depth (displayed by LittleBlitzerGUI) is nearly the same...interesting. But it seems, that DON is measureable weaker than Stockfish 140129 (35%-65% scoring in this small head-to-head-match).

Stay tuned!
