Re: how far is too far: houdini for sell?

The easiest way to deal with rule #2 is to tie it with a legally binding issue. If the code is legal then it is OK, if it is not legal in a court of law ... then it should not be allowed. At the moment things are in a very strange position, where you have people with differing opinions hacking it o...

Re: Code comparison with Rybka, Houdini, then Chiron

I dont understand the difference between suspecting Houdini or suspecting Chiron. kgburcham One is proven the other is not (in fact its not even close). Happy? God I f***ing hope so. Its a quality answer. :) Chris you did not answer the question. I said what is the difference in the suspecting of e...

Re: how far is too far: houdini for sell?

I like radical ideas, or at least the discussion thereof, because they help us look ahead. I completely agree with you we face a new reality and that it is wise to reconsider what we want with these tournaments. To me that is the only discussion worthwhile at this moment. Marcel, 100% agree. All of...

Re: Code comparison with Rybka, Houdini, then Chiron

It shall be done to Junior, Fritz, Hiarcs etc. ? if you can present clear indications that the above mentioned programs are clones of XY it will be done for sure, at least when they start at the next major programmers tournament. For the moment to my knowledge no such indications exist. They are no...

Re: Code comparison with Rybka, Houdini, then Chiron

Several have compared Rybka code to Fruit/Crafty. Ippolit, Robbo code to Rybka. Houdini code to Robbo. Of course now it is time to compare Chiron code and see if it has any dirty nasty code. Now if Chiron is rated 2000 to 2400 then who cares but if Chiron is rated 3000 then it also needs to be comp...

Re: how far is too far: houdini for sell?

I simply state facts. You are EXACTLY in the same boat as the few remaining Rybka fans. Sorry that you don't like FACTS, but fact is, houdini is based on Robolito. Ton of evidence to support that, more coming each day. Learn to live with it, because it is NOT going away... You are fighting a phanto...

Re: Houdini with 1:1 Robbolito-code?

Well, Robbolito is pubic domain, right? So there would be nothing wrong with this. The Robbolito versions that are being used in the code comparison above are 0.085g3 and 0.09. These have been meticulously translated to common English programming terms. The are greatly modified, improved, stronger,...

Re: how far is too far: houdini for sell?

Right, that's absurd! I don't think Robert Houdart used that nickname for building Robbo. It must be someone else.... But the clear point is: can an anonymous author claim GPL rights and/or moral rights? Yes (the attribution rights, that is). And will they succeed? There is no prior jurisdiction of...

Re: How Much Ram Can Modern Chess Programs Use?

I guess most 64-bit programs can use whatever you have. (32-bit programs are probably limited to 2GB.) With a good replacement algorithm I once measured that search speed went up as the 12th root of hash-table size. As Elo scales with speed approximately as 100*ln(speed), this would give 8.3*ln(has...

Re: how far is too far: houdini for sell?

Robert, you know that there is a big big difference. All programs are based on a lot of ideas of a lot of persons. Just make one simple statemtent: a) Houdini starts or shares a lot of code with engine XXXXXX b) Houdini is completely original and does not share any code with any other engine. if a)...
