Re: End of Era is there: SF is finally beaten!

Like another user pointed out, "How are we sure we are playing against chess engine and not the games database? And when does the multimillion game database end and the chess engine begin ?" The answer is: by understanding what Leela does. (Or, if one does not have the time or inclination to study ...

Re: End of Era is there: SF is finally beaten!

... There is no any "spectacular" and there is no any "plan" on the side of Leela. In reality the position after 19.-c4 and the good continuation is in the 32930net of Leela. To prove this I used the weak GTX 1060 to find the 20.Bg6 move. From net30100 to net32000 Leela want to move 20.Be4, 20.Bxc4...

Re: chess programming - predictions for the next 5 years

let's address the first point, improving tactics... it seems ironic that I not only suggest but RECOMMEND improving tactics... aren't AB searchers tactical beasts? well, not really... :) what happened was that, once engines bypassed humans in tactics, their tactical sharpness started to degrade... ...

Re: Recommended important files to keep on SSD for 7-piece Syzygy

Don't the files with pawns in them require the underlying files with the pieces promoted? Not if you don't care too much about being able to win a winning TB position. A probe of a 7-piece WDL table may do probes of 6-piece WDL subtables (reached through captures), which means you need those subtab...

Re: compiling stockfish with more options

Besides i already use stockfish derivatives with many options, i just was curious if i would be able to make one of them on my own, but its not most important. So it is possible and not all too difficult, but it requires a bit of knowledge of C++ and several modifications to the source code. Since ...

Re: compiling stockfish with more options

Here is my problem. I can add new tuning option just visually by adding something like "o["X"] << Option(100, 0, 100);" in ucioption.cpp but i cant actually connect it in proper way to some value. For example i want for "X" to change parameters in types.h file, we can say "QueenValueMg". QueenValue...

Re: compiling stockfish with more options

I have no problem with changing values by this tool, but its quite time-consuming to make a guess and then make .exe one by one with small fluctuations of values. If i have possibility to change values from uci menu in gui it would be incomparably faster for engine tests (faster like faster is copy...

Re: Interesting article in "Nature" on Machine Learning

The paper itself is also available: https://www.nature.com/articles/s42256-018-0002-3 Our focus is on a specific learning problem we call ‘estimating the maximum’ (EMX). The EMX problem belongs to both models discussed above. Here is a motivating example. Imagine a website that is being visited by a...

Re: Interesting article in "Nature" on Machine Learning

See also here . Ben-David and colleagues then prove that the ability to carry out a weak form of monotone compression is related to the size of certain infinite sets. The set that the authors ultimately use in their work is the unit interval, which is the set of real numbers between 0 and 1. Their r...
