Students are quite good at this kind of obfuscation. One can do the above to improve speed (one popcnt vs N BSF instructions in a loop) or to make the code appear to be different (both do the same thing, but look significantly different, particularly if you change the variable names as well... You ...

About copying, rewriting of code and so on. In eval-function of Ivanhoe we can find: U = (POSITION->OccupiedBW >> 8) & wBitboardP; while (U) { b = BSF (U); MobValue -= PawnAntiMobility; BitClear (b, U); } Robert Houdart replace this at: U = (POSITION->Oc...

So I guess it will be ready in April. If we add some time as these predictions are always ...

It would seem to me that by asking multiple times for his permission to commercialize Strelka, that you clearly felt he had this authority. I asked permission of Vasik only once. Hmm.... " ...I would like to ask once more ... " Vas previously not objected to the commercialization of Strelka: "Selli...

It would seem to me that by asking multiple times for his permission to commercialize Strelka, that you clearly felt he had this authority. I asked permission of Vasik only once. This was done for two reasons: 1. Vasik promised to make a mobile version of Rybka. 2. Strelka was partly based on Rybka...

My letter to Vas in response to his questions (translate by V.Zakharov): Hi Vas, First of all I would like to excuse for my public pronouncements, that Rybka was developed on the basis of Fruit. There were only subjective guesses and I didn't have right to share unchecked thoughts publicly. Unfortun...

Are you claiming that you did not suggest Strelka be packaged with Rybka as a variant/flavor of it? That was the reason I was even brought in. As a variant of his program, his permission was required, and frankly, the idea wasn't a happy one since it wasn't just a variant, it was a variant in which...

Yes, the links are bogus though. The statements predated his later admissions that Strelka was heavily based on RE of Rybka, though there were a number of parts of the RE that were incomprehensible to him. He also added parts of Fruit and other things, which was what made it such a strange patchwor...

My first pseudonym on russian computer chess forum was "natasha strelka".

In the case of Rybka, the reason for the slowdown and the growth of a tree in the won positions lies in the method of evaluation hashing (10 bit).
Houdini uses a different method of hashing.
