Fire 5 is out!

[pohl4711]

Strings were found in Fire.5, unpacking:
Code:
position w - - 0 10 /8/8/8/8/8/8/ KPK KNNK KBNK KRKP KRKB KRKN KQKP KQKR KNPK KNPKB KRPKR KRPKB KBPKB KBPKN KBPPKB KRPPKRP map/set<T>



This is the Stockfish-code that produces this output of strings in the executable and which is located in the file endgame.cpp:

Code:

// Get the material key of Position out of the given endgame key code
// like "KBPKN". The trick here is to first forge an ad-hoc FEN string
// and then let a Position object do the work for us.
Key key(const string& code, Color c) {

assert(code.length() > 0 && code.length() < 8);
assert(code[0] == 'K');

string sides[] = { code.substr(code.find('K', 1)), // Weak
code.substr(0, code.find('K', 1)) }; // Strong

std::transform(sides[c].begin(), sides[c].end(), sides[c].begin(), tolower);

string fen = sides[0] + char(8 - sides[0].length() + '0') + "/8/8/8/8/8/8/"
+ sides[1] + char(8 - sides[1].length() + '0') + " w - - 0 10";

return Position(fen, false, nullptr).material_key();
}

} // namespace


/// Endgames members definitions

Endgames::Endgames() {

add<KPK>("KPK");
add<KNNK>("KNNK");
add<KBNK>("KBNK");
add<KRKP>("KRKP");
add<KRKB>("KRKB");
add<KRKN>("KRKN");
add<KQKP>("KQKP");
add<KQKR>("KQKR");

add<KNPK>("KNPK");
add<KNPKB>("KNPKB");
add<KRPKR>("KRPKR");
add<KRPKB>("KRPKB");
add<KBPKB>("KBPKB");
add<KBPKN>("KBPKN");
add<KBPPKB>("KBPPKB");
add<KRPPKRP>("KRPPKRP");
}


And the conclusion is: Fire 5 code contains the same endgamestrings as Stockfish and in the exact same sequence...So, there can be no doubt about, that Fire 5 has taken code from Stockfish. And the Fire 5 code ist compressed with MPRESS to hide that fact and makes it harder to investigate the code.
It is really a shame. Fire 4 was an interesting engine. Fire 5 is not.

Use of software packers is extremely commonplace, from small software development firms to large corporations.

It's been standard operating procedure on 'release' versions for every company I've ever worked for.

There are several advantages including less disk space, faster downloads, faster load from disk to memory, etc. and yes it is a deterrent to hacking.

Fire 4 was also packed...

To be fair, this discussion should be conducted in the engine origins forum where it belongs (right alongside the current Houdini 5 topic)

Not knowing any Spanish (or Portuguese?), I put the phrase into google translate.
It gave "Fool of the ass came out the clown"

Google also said
Did you mean: Tonto del culo salió el payaso
(with an accent on the o of salió, incase you do not see this in your browser)
That translated as "Silly ass came out the clown"

He is the one making an ass out of himself...

Translating it to swedish you get 'idiot kom clownen', meaning 'idiot came the clown'

I think we're even further away from it now...
