You haven't got a clue.


In fact if we kick out the deep futility out of ivanhoe, which is an obvious and illegal Rybka/Fruit clone, and add a very old years 90 extension, then we have Houdini.



If you don't mind please let us know exactly what years old "90" extension you are referring to. Frankly, if some old idea has been shown to help a modern program, I'd like to try it in Komodo. Regarding "deep futility", are you saying that Houdini reduced the maximum depth at which Ivanhoe does futility? If so we already use less plies of futility than Ivanhoe in Komodo. Do you think this reduction could explain a significant part of the elo gain of Houdini 1.5 over Houdini 1.0/Ivanhoe?
For the record, I don't think we are using any original Houdini ideas in Komodo, if there are any. I think we are using one or two Stockfish ideas that found their way into Houdini.
This raises another question: Is looking at decompiled code for the purpose of seeing what old ideas have been resurrected in a different ethical category than looking at decompiled code for original ideas?
