Re: When will we see HOUDINI in official tournaments?

As someone who is not a scientific expert of the similarity tool test methodics, I would like to ask: Is this method capable (enough) to spot differences of search code , not of evaluation only? Especially the fact that the calculation times per position were varied (*) depending on the engine's st...

Re: When will we see HOUDINI in official tournaments?

Ed, I don't know and I don't care. Success of Houdini 3 will not be measured by its similarity score but by its 40+ Elo increase over the previous version. It's important because people would like to see the strongest engines in the world to meet and compete. Can you please return to the case at ha...

Re: When will we see HOUDINI in official tournaments?

I suggest to wind this Critter issue down in this thread. Mentioning the similarity is a fact, but everything else... we are walking on thin ice. Miguel The point of my post was not "accusing" Critter (I don't really care about that). My point was about the "60% rule" which may prove not to be very...

Re: When will we see HOUDINI in official tournaments?

The more relevant issue is if your current engine stays below the required 60% similarity, which is already pretty tolerant. LOL. What a joke. I notice that the first CSVN tournament (Leiden) that is supposed to use this "60% similarity" rule has accepted Critter as participant. Surely you're aware...

Re: When will we see HOUDINI in official tournaments?

A similar question was asked nearly 2 years ago (see here ). The answer is still the same: time, money, relevance. Participating in tournaments is probably good for marketing, but hardly relevant for my goal of creating the best chess engine. I am sure the CSVN can provide a good operator for you. ...

Steve, I will ask Johan. That is, in case I don't forget.

Re: Possible LMR improvement using AB_FOOL

SImple question... would you really trust information from a simple 4-ply non-alpha/beta search over the results obtained from a 20 ply normal alpha/beta search, for anything at all??? I see moves with high scores at 4 plies that are losing at 20 and beyond. So keeping that stuff doesn't seem reaso...

Fern, ah yes, but my recurring virus has been trying to improve my sorely lacking golf swing, which has many advantages over programming in I can pursue that activity outdoors! ;-) However, I must say all this posting has gotten me curious enough to take a look at some of the open sources out there...

Re: Possible LMR improvement using AB_FOOL

Sven, Dan, of course you are right. Each root-move needs [-inf ... +inf]. I get 35 elo doing it the OP way, maybe there is even more now :lol: I hate to rain here, but I don't see how one can get +35 elo from just adding LMR at the root. That would suggest that you have speeded up your search by a ...
