Re: Leela, such a great engine (and innovation)?

And finally, there is a huge difference between "I am convinced." And , "It has been proven." What's the difference? Really, I keep saying "Magnus Carlsen", "Magnus Carlsen" like a parrot, but it hasn't been proven to any degree that he's the strongest chess human on earth, yet "people being convin...

Re: Where are the funs of Leela?

As long as the opening is not too lopsided, reversing the opening is a good ides. Nobody is ever satisfied with the openings, even though competent people like Cato and Jeroen work on them. Every good chess player wants their favorite chess opening included. You will never satisfy everyone. The main...

Examples where most people do not extrapolate correctly are the Mony Hall "Let's Make a Deal" problem and the birthday paradox.
Hilbert's Hotel is another good one.

Re: Leela, such a great engine (and innovation)?

The key word here is prove. I don't know if there is someone within 20 Elo, but if there is,we can't prove who is smarter on the basis of the games played. That does not means that we don't have a pretty good guess that is likely to be right. If someone is 100 Elo better you can drive the LOS very, ...

Re: OKE - Opening Knowledge Engines

Rodent's score might well be an artifact caused by the fact that it likes fianchetto and finds/completes it more often than other engines. Other opening-related bits and pieces are penalty for developing queen before minor pieces (but it is quite low and unlikely to influence the result), some code...

Re: OKE - Opening Knowledge Engines

The engines that ere interesting here are those that out kicked their coverage. Rodent and Gideon stand out like sore thumbs. How do the differ in opening eval? For Gideon one reason would be, as already stated earlier, no reductions, no futily pruning etc. --> no loss in the quality of eval. That ...

Re: OKE - Opening Knowledge Engines

I should mention that I always used the three strongest engines (not just Rybka). By the end of the test set Rybka was long retired.

Re: OKE - Opening Knowledge Engines

Well Ed, why bother? We have the excellent "Strategic Test Suite" which "consists of series of themed test suites designed to evaluate chess engine's long term understanding of strategical and positional concepts" (self-description). Dann and his Rybka were the main contributors to it. Here are som...
