Re: Question to Shut Ctf Down posters

Well, not in my opinion. TalkChess is not a free hosting company, and offering space to anyone merely because we feel that it is their democratic right to exist is not enough. It is just what the vote expressed, and it was a minority POV. There has to be a specific reason to exist here to provide s...

Re: Question to Shut Ctf Down posters

37 posters want Ctf shut down. The counting is wrong and intimidating with an already started election. I don't want to be part of this community any longer. This is the entire reason why forums such as CTF shouldn't exist in the open in a community such as this one. They create strife in the commu...

Re: The plea to new democstrocal elections in CTF gets sabotaged

I do not understand why the CTF forum even exists. The content that is posted there has absolutely nothing to do with chess and with computer chess even less. There are plenty of alternative outlets for the kind of drivel that constitutes the main content of CTF (last time I looked the chief racist ...

Re: Chess solved?

What the OP wants to say is that there might be some "easy" algorithm that predicts the game theoretic value of any position. It might then be possible to verify the correctness of such an algorithm mathematically (it should give the correct value on terminal positions, a predicted lost position sho...

Re: SF-NN embedded

I think the embedded file is misguided. For instance, I build a bunch of different binaries, and shall each one have a 20MB pile of goo sitting in it's data space? Imagine if all of the stockfish variants follow suit. Then we will have 3-4x 20MB pile multiplied by variant count. I think it would ma...

Re: Stockfish has included WDL stats in engine output

Before discussing the SF wdl data one should understand what they actually represents. There are two principal definitions of wdl. Given a particular position one could define it as the empirical probabilities that an engine scores a win,draw,loss against itself when playing from that position. Most...

Re: Stockfish has included WDL stats in engine output

If you want to end up with real win rates, just run a long match with SF against some other engine or against itself and collect the stats. It's not so clear how to objectively measure the win rate of a particular position. One must have some method for introducing variety. The method one uses may ...

Re: Throwing out draws to calculate Elo

This whole discussion is very strange. Lots of useless words for things which are well understood and well known. LOS is a Bayesian concept. Hence it is not an empirical probability but a degree of belief. Formally LOS is the probability that one engine is stronger than another assuming a uniform pr...

Re: Repeating games with switched colors reduces Elo error. All matches should be done like this

This only applies to tests with the same opening book for both sides. It makes intuitive sense that the results will be more accurate if player A and player B play both sides of all openings. But I couldn't find any empirical results so I wrote a utility to test it out myself. First, I've compared ...
