Re: Testing of Asmfish in CCRL?

Asmfish is not equivalent to a faster Stockfish, it has a few differences impacting on the strength (around 1 or 2 elo?) and is faster. If one is looking for a faster Stockfish, there's Pedantfish. So the bench is not the same for Asmfish than for Stockfish. Your info is out of date by five months....

Testing of Asmfish in CCRL?

I wonder if there's any project to test either Asmfish in the CCRL. I fail to understand why Sugar was tested and not Asmfish. Asmfish is not equivalent to a faster Stockfish, it has a few differences impacting on the strength (around 1 or 2 elo?) and is faster. If one is looking for a faster Stockf...

Outcome of Crazyhouse with perfect play

While there are some indices that chess may be a draw with perfect play, such as the increement of draw percentage between strong engines. Especially when they are made stronger by increasing the time to calculate and/or increasing the number of cores/threads... I was wondering whether Crazyhouse wo...

Hardware questions about cores and threads and /proc/cpuinfo

I have a quad core i7 7700, so 4 real cores and 8 threads or virtual cores. In Linux when I do cat /proc/cpuinfo | grep MHz I see 8 listed frequencies and they don't necessarily matches by pair. Without using grep, I can see that these frequencies are for core 0, 1, 2, 3, 0, 1, 2 and 3 in that order...

When did chess engines running on common home pc hardware be

When did chess engines running on a common home pc hardware became stronger than the strongest human? Was it around 2006? By common home pc hardware I mean the kind of hardware people would buy (like Intel core 2 duo E6300 back in 2006). I am excluding server machines. I am interested in which hardw...

Re: Another attempt at comparing Evals ELO-wise

Hello Tsvetkov, I think it doesn't make much sense to compare an engine X to an engine Y at fixed depth like you did. That's because the definition of depth differs between engines (it is an iteration of something different according to which engine we consider). There are other more meaningful ways...

Re: Chess power of Ryzen processor

Nice, but as far as I've gathered knowledge on this forum, solving puzzles does not necessarily correlates with strength. This is why in order to see which engine is best, you run full games, not solve some positions only. Thus, I don't think your sentence So it is obvious that for an overclocked Ry...
