I'm glad you're having fun testing! I looked at the source code of Hypnos 190324. The engine is not as new as the date. Most of the code is about 2 months old. It was mixed, old code with new code. That doesn't have to be bad, but old parameters were mixed with new parameters. From what I've heard, this version of Hypnos is not MZ himself. MZ provided only a basis and others are now experimenting with it.

Allign to: "VVLTC search tune"

That is not correct.

Here only one example, there are many more:

SF dev. "VVLTC search tune":

Depth Search::Worker::reduction(bool i, Depth d, int mn, int delta) {
int reductionScale = reductions[d] * reductions[mn];
return (reductionScale + 1107 - delta * 725 / rootDelta) / 1024 + (!i && reductionScale > 956);


HypnoS 240324:

// Reductions lookup table initialized at startup
int Reductions[MAX_MOVES]; // [depth or moveNumber]

Depth reduction(bool i, Depth d, int mn, int delta, int rootDelta) {
int reductionScale = Reductions[d] * Reductions[mn];
return (reductionScale + 1346 - int(delta) * 896 / int(rootDelta)) / 1024
+ (!i && reductionScale > 880);


SF dev. VVLTC search tune

for (size_t i = 1; i < reductions.size(); ++i)
reductions = int((19.80 + std::log(size_t(options["Threads"])) / 2) * std::log(i));

HypnoS 240324 VVLTC search tune

for (int i = 1; i < MAX_MOVES; ++i)
Reductions = int((20.37 + std::log(Threads.size()) / 2) * std::log(i));


HypnoS 240324 is (fake) OLD SF CODE "VVLTC search tune"

My dear friend Eduard,

It seems that these codes are really about 2 months old. We have a small request to Marco Zebinati, we want a new version of your own.

Also, I didn't know your book was for sale and as I said, I found it on a torrent site. It says solista attack 8.1.bin. I can delete the book if you don't want me to use it. I trusted the book when I saw that it belonged to you. It's an old version, but it's still very good.

Best regards,
Fringe
