And the Ippolit author is...

[Dr.Wael Deeb]

Running a match between Ippolit and Rybka. Compared to other results I have seen with really long timecontrol: 2min/game + 1sec/move. The match is running under Fritz 8, Rybka with Rybka book, Ippolit with Fritz 8 book.

Rybka contempt set to 0 as advised by some here.

Results so far:

20 games, Ippolit won 6, Rybka won only 1, 13 draws. That means according to Fritz +88 ELO.

So it looks like that Ippolit wins also vs. Rybka 3 with contempt 0

One interesting observation:

The absolut score is mostly similar between both. If there is a change in the score, Ippolit can see it 2-3 moves before Rybka. Similar evaluation and better search in Ippolit?

I had also some time losses under Arena. No hang, just loses on time. Maybe, and now I indeed start speculating, maybe Yelin implemented a special Arena feature because of the Patriot 2 desaster (Patriot 2 should have been sold via Arena, but turned out to be a Fruit clone). There is no reason why an engine should stop playing under Arena and not under Fritz. After the game has started the protocol is handled in the same way by both GUI's.

Vas confirmed the engine is a clone of Rybka

The Rybka guys don't like the idea of an engine stronger than Rybka 3, which is NOT based on Rybka. This statement is done without any proof.

It is much more likely that Ippolit is a patchwork of several engines, based on Kaissa. It is even possible only ideas where taken from other engines, as most other authors do it.

The Rybka guys can bubble whatever they want....as I stated yesterday,I don't buy this $hit anymore....

With latest Robbolito version it says:

id author Yakov Petrovich Golyadkin, Igor Igorovoich Igoronov, Roberto Pescatore

Are these true names or is this only joke?

We have a little mistake in the second name. It should be:
Igorovich

We have two versions:

1. Rybka 3 binary ->
disassembling ->
rewriting on C ->
algorithm understanding ->
rewriting on new engine ->
Ippolit.

2. Intermediate Rybka 4 sources ->
[without disassembling, rewriting, understanding and so on] ->
Ippolit.

What version is more reliable?

What version is more reliable?

The first possibility would be too much for a single man.
I think the second option is more probable, with a team of three man.

Version 3:

Kaissa + Crafty + Fruit + Toga + Strelka + Rybka (not necessarily Rybka 3, maybe only the parts from Strelka) like described on the Ippolit webpage, and like a few similaries between the old Kaissa and Ippolit confirm.

What version is more reliable?

I think the first option is almost science fiction....it would take way too long to be accomplished....

I think the second option is even more impossible....Vas is not that naive to allow his new source code to be taken that easy....

A real mystery indeed....

I really dont like all that speculation.

If its a clone (and the author is not a talented computer programmer), soon Rybka will overcome it by new additions and work.

If it is not a clone, its really a pitty for so much hostility.

Scenario 1 is really hard to believe its true. So much work to create a clone? Doesn't that guy have anything more useful to do? Scenario 2 would make a really good movie.

Alex,

nice to meet you again!
Hope you are right!

Exactly!
At first I am not many thinking about it. But I remember me on the sentence he wrote in the latest mail contact I had with him.

"Later, I will come back and the World will see what I can do".

Best
