Re: TEST position TCEC5- Houdini 1.03a-DRybka4 1-0

Since I don't have saved copies of these lists, and I don't know if histories of said exist for perusal anywhere else, I have to use archive.org. Using the standard 40/40 list from CCRL, starting May of 2007, or about the time that Rybka took its place at the top of the chess program world, and taki...

Re: TEST position TCEC5- Houdini 1.03a-DRybka4 1-0

There we go again ... all Rybka's are clones of Fruit and Ippolit is not RE from R3. I think if you would put up a Poll and ask who believes that R3 is a clone of Fruit, very predictably you will get the same clueless group voting that R3 is a Fruit clone and that Ippolit has nothing to do with R3....

Re: TEST position TCEC5- Houdini 1.03a-DRybka4 1-0

[snip] I'm not interested in rehashing who or what new program is or is not a clone of Rybka [snip] Yeah, you are. You came back again after stating the same thing earlier. I'm afraid that I don't see the point to your last post, unless calling me names and flaming me is the goal here. I suppose yo...

Re: TEST position TCEC5- Houdini 1.03a-DRybka4 1-0

What do you think the answer is? I looked on the IPON rating list and Fruit is 2626 ELO, and 32 bit Rybka on this same list is 2849 which is a difference of 223 ELO points which is massive. It's much more if you consider the 64 bit version. Isn't that a bit like comparing apples to oranges? The ent...

Re: Jeroen Noomen wrote me this post:

I don't quite follow the logic here. Mr.X has more important pursuits than working to produce Y, but it is OK if he steals it from Mr.Z, who has worked hard to produce Y, because if Mr.X would have worked as hard as Mr.Z, he could have produced Y too. Is that it? Nope. It has nothing to do with whe...

Re: Chessbase article. WTF? Please explain.

NPS numbers mean literally shit when talking about clusters. The real efficiency of Rybka cluster is at best 50 (meaning 50x speedup in average time to fixed depth compared to its single core). 50 is most probably largely exaggerated number, but lets just take it. This means that (in)famous Rybka c...

Re: Jeroen Noomen wrote me this post:

Of course, Mr. Rajlich has had four years to improve Rybka, while the alleged cloners have had less than a year to improve their engines. Also, I believe that Mr. Rajlich has said that he makes his living off of Rybka and its associated software, etc., while the alleged cloners are working for free ...

Re: TEST position TCEC5- Houdini 1.03a-DRybka4 1-0

It's apparent to me that if Mr. Rajlich were to bring a lawsuit against the clones, he would need to ...identify who he was suing. You could probably do a better job of that than I could. That's one of the problems Mr. Rajlich would face with a potential lawsuit. There are several other hurdles tha...

Re: TEST position TCEC5- Houdini 1.03a-DRybka4 1-0

So this thread has, like many others I've read here and there, transformed into a "Houdini/etc. is a clone of Rybka is a clone of Fruit" pole-waving match. (NOTE: Those significantly familiar with the whole clone of Rybka which is a clone of Fruit controversies and related arguments might wish to sa...

Re: New Engine: Deep Saros 2.3c3

If the clones can easily be proven to be tweaked versions of Rybka (eg using large portions of code that didn't exist before Rybka was published) then why doesn't Vas take legal action against the "authors" of these other engines? What should he list in the charges? "These people stole the code I t...
