Booot 6.3 Release

[tmokonen]

I see the maximum number of threads has been increased from 16 to 64. It will be interesting to see how Booot fares in the next edition of TCEC.

[Fuddur]

Nice progress!Every chess engine must have the android version.

Dropbox and inactive accounts cf. https://www.dropbox.com/help/security/e ... ve-account; my former account there was deleted after a year.

Great news! Thanks Alex and good luck in Stockholm.

[Colin-G]

Thanks for this latest version, which I downloaded today.
Booot just keeps getting stronger.
Would I be wasting my time trying to compile a native linux version from the source code using lazarus (linux version of Delphi) and FPC, or is it only for Windows OS?

Hello:

Dropbox no longer allows direct downloads and their signup/login system is broken: "unable to complete this request" upon login. Using the Google account option leads to about 20 pages of CAPTCHAs. At any rate, there shouldn't be an account requirement to download a file that's supposed to be freely available to everyone.

I just downloaded it without even logging in. Top right corner, download > direct download.

Yes, direct download was successful for me too, although I had to try twice.

Indeed, why make it easy. Likely some new collaboration of a kind, but the small part in the right upper corner - direct downlod - worked for me as well.

For those who have had problems with download, other option is replace the last 0 of the URL by 1, that is, enabling dl=1 (download = yes) instead of dl=0 (download = no). It works for other Dropbox links according to my experience. So, for Booot 6.3, the following link should do the trick of allowing a direct download:

https://www.dropbox.com/s/soy5ux773vm1w ... e.rar?dl=1

(I copied the link of the OP and replaced the last 0 by 1, I do not know if there is an upgraded version of Booot 6.3 already out).

Regards from Spain.

I support this question: is it possible to compile a source version of the version under linux?

[Kotlov]

Good day all!

Here is the link for the new version of my engine: https://www.dropbox.com/s/soy5ux773vm1w ... e.rar?dl=0
As usual, archive has Pascal sources and executables for x32, x64 and x64_popcnt.

This version will play in Stockholm soon. According my tests it has some good improvement (about 70-100 elo). But my tests a short, quick and unfair .

So, who likes Booot - just enjoy it!

Best regards,

Alex Morozov.

Но почему именно Паскаль?
