Re: Writing bugs

State is fine but it should be encapsulated in an object. Like so: rg=random_generator(seed) r=rg.rand() The state maintained by the rg object could be much more complicated than a single number (this would likely be the case for a cryptographically secure random generator). The rg object completel...

Today I had a new one, took me hours to see it.
Why didn't your compiler warn you?

Re: Can you improve CPU performance with Intel library?

It depends on what calculations you are doing. If you want to speed up big matrix multiplications, FFTs or other numerical code (and you don't want to push it to the GPU), MKL can help you. But an alpha-beta chess engine does none of that. NN engines do big matrix multiplications and convoltions, bu...

Re: 7 Man Syzygy and SSD **Hashes**

I don't seem to be able to find a list of MD5 hashes for 7 piece tables. I'd like to verify my downloads are not corrupt. Could someone point me to a list of hashes? Thanks Mike No MD5, but something better: http://tablebase.sesse.net/syzygy/7-DTZ/SHA256SUMS http://tablebase.sesse.net/syzygy/7-DTZ/...

Re: Don't use databases

Speaking of 18… when you have the last 18 replies to your own thread, with nobody else interested, perhaps it's time to call it quits.

Re: Komodo 12.3 is out

I do not think Larry every had source code for Rybka. But anyway, if GUI writers would come up with a UCI spec for examining game trees in memory, the data is certainly in Komodo MCTS and I could the PVs available. For analysis.sesse.net, I chose to simply do it outside the regular UCI interface. T...

Re: Leela

What Guenther says. It's unclear exactly what you're asking for, beyond just someone pressing the button to pull up a GPU-enabled AWS instance and installing Leela on it?

Re: Alphazero news

From an obfuscated program one can get its source (or at least what works similarly ) if the program is running. You don't need the program to be running for that, just as much as you don't need a C compiler to understand what a C program listing does. If the program is not obfuscated you can do th...

Re: Alphazero news

I'm not sure how you arrive at that conclusion. Google in general open-sources software for a lot of reasons, probably fairly similar to how other companies that deal with OSS works. Look at the amount of stuff flowing into the Linux kernel—is that for “only for PR purposes”? If so, that's really e...
