Re: Random mover win rate

I would expect a 50% score against itself (i.e., two identical random movers facing each other), with sufficient number of games.

Re: Severe windows 10 problems. What to do?

Maybe there is still a very subtle bug in Microsofts threading library, it would not be the first, the last year they removed several bugs in this subsystem. Pretty soon I will have a Linux system up and running and I just want to see if it also crashes when I compile my engine with GCC. Why not gc...

Re: Self-taught AI solves Rubik's cube.

Hello Sven: I think the speedcubing numbers are way too large, I have more confidence in the Wikipedia numbers . The speedcubing approach sees a 3x3x3 cube (for instance) as consisting of 27 pieces that can be moved. But in reality there is one "invisible" piece in the middle that is irrelevant, an...

Re: Self-taught AI solves Rubik's cube

Another question is, do n x n x n Rubik's cubes actually exist with even n? If so, how many "fixed" central pieces do they have (0 or 24)? If they only exist in mathematical theory then why should they be relevant for us?

I just found the error, somehow a statement in the hash update disappeared like I expected.
Aren't you using a version control system, e.g. Git? It would be a trivial task to review all changes when using Git.

Re: backward pawn

In my view f5 and h5 are not backward but g7 is. My reason: the statement "the backward pawn is not able to push forward without being lost" (https://www.chessprogramming.org/Backward_Pawn) is not applicable if the stop square is occupied. However, available definitions vary a lot. CPW points to som...

Maybe I should try second option: Create Windows 10 installation media
But therefore I first have to buy USB with at least 8 GB. My current USB sticks only have 4GB.
A 32 GB USB stick should be available for much less than 10 EUR. So not much of a "but" ...

Re: Severe windows 10 problems. What to do?

For instance starting explore.exe from a cmd does not work. For it says can't find explore.exe. But if I go to c:windows32 I see an explore.exe. But cannot execute it somehow. So what to do instead of buying a new computer for that is an expensive solution. And maybe I will get these problems in th...

Re: tuning for the uninformed

Eval value is always as white POV. That is different from what Sven says? No, why? I said "same viewpoint" and if the stored value is from white POV then eval must be white POV, too. My example was more general and did not assume white POV, it was only made to show what would happen on a viewpoint ...
