I compared the code of Ippolit and Rybka 3. There are a lot of matches. But in general the code very seriously rewrited. I think that this could be done only by author of Rybka. I think that Ippolit - intermediate version of Rybka 4.
About "nonhuman" parts of the code I can not say anything. Rybka 3 do not have these parts.
And also.
I do not think that Ippolit was obtained by the reverse.
For example, it has a lot of constant expressions. The compiler evaluates such expressions, and the binary contain the numbers. Reset the expression from these numbers is quite difficult.
I put the two posts together, it is easier like that.
Correct me if I am wrong about what you say.
1. There are a lot of matches.
In what way? What do you see that are matches? Too many matches with Rybka so that it icould only be based on Rybka itself (in your opinion)? I know other people have said this as well.
2. The code is seriously rewritten.
Yes, it is. Most if not all of those we spoke to said the same thing, but also they said that they could not imagine a person would write code in this way. Mostly they said "it's a mess Chris".
3. You think that the code could only be made/done by Vasik.
Could you tell us why? I mean, what is it about the code that make you think that. Is it because you see the same code in Rybka?
4. You think that Ippolit - intermediate version of Rybka 4.
It will be very interesting to see what the finished Rybka 4 is like, so we can see if there are similarities between Ippolit and it. Whether or not the conspiracy theory that this is a marketing ploy sticks or not, the fact remains that it would be questionable to give away a source (even partial and mangled) of a commercial product. You can't discount the idea but it is questionable.
5. I do not think that Ippolit was obtained by the reverse.

Some time ago there was a version of Rybka 2 that appeared that did not have symbols stripped. Would that help someone who wanted to do that?
Sorry, if there are a few questions here. It is only about what you think and your opinion. We also asked quite a few people. Adding such opinions (for that is what they are) together helps to gain a good overall picture.
