Re: Verify integrity of Syzygy TB with MD5

I saw this as well, but I wasn't sure what I should type inside "filepath". I don't want to check all the files individualy (one by one), how can I test multiple files at the same time? And also, does this method compares the two hash (md5) files? Hope I am understood (my english is not the best) :...

Re: Verify integrity of Syzygy TB with MD5

If you're running Windows 10, the easy way (no need to download anything) is doing it in PowerShell:

Code: Select all

Get-FileHash <filepath> -Algorithm MD5

Re: Final Release of Ethereal, V12.75

Imho "choose life instead of chess programming" is a stupid remark. Something that is fun to do IS life. What if it is no longer fun for you. What then? Let me quote Slavoj Zizek: For example, let’s be serious: when you are in a creative endeavor, in that wonderful fever--“My God, I’m onto somethin...

Re: LC0 30x384 (3350) + 2x RTX 2080 Ti vs Stockfish Dev 22.04.2020 + 6 cores + Contempt -75 should be a fair play/ratio

Maybe I'm misunderstanding something here, but what you're saying is: You have a setup in which SF is clearly weaker than its opponent In this setup, negative contempt yields better match results than positive contempt But this is precisely what lowering contempt is supposed to do in this situation....

Re: Speaking of TCEC, what is all this then?

Why are they now playing 100 long games with LCZeroCPU v0.24-n591215? Makes no sense at all. When is Premium league going to start? Because things are not ready yet for the PD. It is supposed to start today (17 March). Normally, when there is something unclear, unplanned or out of the ordinary, peo...

Re: Stockfish Rollercoaster Effect

If white has a score of 0.30 and black has a score of -0.30, it just means both sides believe the other would be in deeper trouble if they played the blunder on this position, than if it was just 0.20/-0.20 or 0.10/-0.10. The old paradigm would show 0.00 and we wouldn't know anything about this. So...

Re: Stockfish Rollercoaster Effect

In the new paradigm, the 30% move increases the chances of white winning, and increases the chance of black winning, so it makes sense that white would show a bigger score for itself, and black would show a bigger score for itself, causing the roller coaster effect . The problem is the user wanting...

Re: question about weak level of engines

I prefer the weak levels to have the following properties: 1)They are not deterministic so humans cannot learn a fixed way to beat them. 2)Their playing strength is fixed and not dependent on hardware or time control. Are there engines with weak levels that have these properties when the levels are...
