Re: to Juri Osipov and BB: in what Houdini differs from Ivan

If the thread is directed solely to Juri Osipov and BB, maybe the OP should have sent them private messages.

This thread is directed not only to Juri Osipov and BB. I asked for their opinions because I think, perhaps I'm wrong, that they are the ones that studied more and disassembled Rybka and ...

Re: to Juri Osipov and BB: in what Houdini differs from Ivan

Since you mention Juri first, I shall grant him the right of first response. One bug that Houdini seems to have introduced is 0x d 5aa55aa55aa55aa for a colour-based bitboard mask.

The order doesn't matter. Even without being a programmer I read with interest all you threads with your code ...

is Critter a clone of Rybka?

I've just read this message from Peter Skinner: http://talkchess.com/forum/viewtopic.php?topic_view=threads&p=393188&t=37948

So you have Houdini, Critter, Ivanhoe, and Rybka all in the same group? Why not just match Rybka against itself or Fruit for that matter?

That's a complete waste of time ...

to Juri Osipov and BB: in what Houdini differs from IvanHoe?

Hello, I've read here and there that Houdini is considered by someone a clone of IvanHoe (or Robbolito). If this is true, in what does Houdini differs from its parent? What are the improvements?
I bet Juri and BB already disassembled it and studied it :))

Re: Is Houdini "dumber" than IvanHoe

Is Houdini's eval more simple and less knowledgeable than IvanHoe's eval, thus trading knowledge for speed in the search function? Are there any easy ways, test suites, etc., to determine these things about an engine?
Houdini has a more sophisticated evaluation function (with more terms and more ...
