Never prune the first move.

Good idea!

Any chance to see Discocheck in the next nTCEC season?

Thanks.

No. TCEC is only for SMP engines.

Very nice. I am currently watching DiscoCheck 5.2 crush Texel 1.02 on my linux test computers. +110 elo after 2526 games at time control 1s + 0.08s/move.

One small detail. The README.md file says:

Code: Select all

On Linux (or POSIX), with g++ installed, simply run `./make.sh` to compile.

However, you need to specify the executable name or else the compiler gives lots of errors:

Code: Select all

./make.sh dc52

1"+0.08" is really fast! There is an UCI Option called "Time Buffer" in DiscoCheck. By default, I put it as 100ms, but for such time control, assuming you're using cutechess-cli (hence minimalistic lag), I would use Time Buffer=10. Perhaps you have a similar option in Texel, or maybe it's hardcoded. To compare apples and apples, makes sense to make sure they both use the same.

Ah yes. I should probably just modify the script so that $1 becomes an optional parameter with a default value like './discocheck'.

Yes I use cutechess-cli. Texel has a hardcoded time buffer set to 1 second. Changing it to 0.1s gives about 30 extra elo points in self play at this time control.

I could make the time buffer a UCI option but I don't like the idea of people setting it too low and then complaining about texel losing on time.

Hello, Maestro Tony !

THANK YOU, but under Win XP both binaries (DC 5.2 & M 1.0) need:

-libgcc_s_dw2-1.dll
-libstdc++6.dll
-& so on !
