I am sure all the above means something to many (above my old head). However it would seem that it is not possible to obtain this engine anywhere, so really
the question is what is the point of the post?

My hobby is to analyze everything I arouses curiosity. i have following the story of this engine called Synapse. In talkchess the authors of the komodo argue it is a clone of their engine. Many others say that is a clone of Stockfish and still others say that is a clone of Gull. I managed to get Synapse by a friend, so I just looked at the structure of the three engines and published the same to seize evidence of cloning that I, in truth at the moment and structurally, I do not see ...

As on one can seem to get hold of it, does it matter one way or another?

forgive me but I did not understand your question, please help me understand what you mean ...

It is just you are telling us how you have run some tests on a engine which most of us are unable to get, therefore although your tests etc. may well be important to yourself
they are not much help or use to the rest of us, who cannot get the engine anyway. I hope that explains it.

ok, now I understand perfectly!
Thank you for your opinion.

So what is the result?
Is it clone of another best engine or is it really original?

I can not say for sure if it's completely original or if it is inspired by other engines. the data show that it is definitely not a simple clone ...
In the file .exe, also, are included the  data encrypted of the recipient of the engine and if you try to edit the file it is not working.

Having spent many hours studying the unpacked file of this mysterious engine called synapse I can finally say with certainty what it is.
It comes as a stand-alone .exe file, and corresponds to a chess engine in UCI form, and so far nothing strange or new. But how does? is an original engine? these questions I can finally give a definite answer, but before i must mentioning two old programs: Triplebrain and Chesscombi.
Synapse is in fact the result of the evolution of these programs, is the result of the combination of two other chess engines that, depending on the choices of programmers, takes on characteristics similar to this and that engine.
The very news is that the engine is delivered to the user in the final version, so already set, no need to "mount" each time as to chesscombi.
Analyzing the file emerges a sort of hybrid code, my opinion is that programmers use systems capable not only to unite but also to make compatible and perfectly coexisting two different chess engines in one.
The first part of the file is represented by engine "main". The second part of the file is represented by engine "secondary" more the part that manages the entire file and allows it to function properly.
According to Alejandro Torres, "Synapse uses ideas of engines freely distributed."
....closed story for me!

Interesting response.
The imagination has his ways...

This program is protected with Themida, to open it takes only Reverse engineering programs. A once opened (which is not easy) the file as I wrote shows three sectors. I recently had the version Deep Synapse 4.8. In the first sector there is about 95% of the Stockfish code, in the second sector Houdini 3 (in turn protected). how it run I do not know, but the fact is that they are two engines in one file.
If someone expert in Reverse Engineering wants the file, write to me privately and I'll pass the file as I was given.

You who are a programmer can understand the differences that are included in these data. If you want to try, i can send you the file ...

The engine play as Stockfish 100%, but the file also contains another engine. What do you want that i am imagining? The other engine is in the file!!!

I am in 101% agreement with Mark Lefler, but I need to understand what makes us a second engine in the exe file!

Here by a test i ran with sim03-tool and both engines Komodo 9.3 and Synapse RZ5.31.



It's a tool downloaded from Komodo site itself. I wonder why Mark Lefler doesn't post these results himself?
Just claiming that ... isn't good enough for me.

54.15% similarity doesn't proof to me those engines are "clones". I believe that the outcome had to be > 65% to claim such a thing.
I believe Stockfish has an higher percentage to Komodo than Synapse has so ...?

With regards,

Alexa1978 and I went the executable, thank you.

I've done the test and I get a derivative of Stockfish...

Code:

C:\sim03>sim -r 1

sim version 3
------ Deep Synapse RZ4.8 64bit (time: 100 ms  scale: 1.0) ------
 59.89  Stockfish 7 64 POPCNT (time: 100 ms  scale: 1.0)
 58.51  Stockfish 6 64 POPCNT (time: 100 ms  scale: 1.0)
 49.61  Komodo 9.2 64-bit  (time: 100 ms  scale: 1.0)


C:\sim03>

ok we agree. But the fact is that the engine "derivative Stockfish" in this case occupies only 35% of the entire file exe. Now the remaining 65% what is it? Have you unpacked the whole file? If you are, then you can confirm that there is code of at least another engine? If you have not done, or if you can not do it sends the file to anyone able to say with certainty what is the remaining 65%. All tests done show that the engine Synapse plays and reveals characteristics of this engine occupying 35% of the file. So my conclusion was to say that it is kind chesscombi or similar program...
Expect your reply!
