New version: Demolito 2017-08-26

Post by lucasart » Sun Aug 27, 2017 6:32 am

About 50-60 elo gain in my testing: self-play, tc=8"+0.08", high resolution book (5 plies). As usual, expect elo compression in rating lists, due to higher TC and longer book lines.

Theory and practice sometimes clash. And when that happens, theory loses. Every single time.

It is quite an interesting project, especially considering how compact the code base is.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Merci beaucoup Lucas !!!

Un gain de 50-60 points élo comparé à la version antérieure de Demolito, c'est sacrément bien :)

Bravo pour ce grand bond en avant Lucas !

From http://www.computerchess.org.uk/ccrl/4040/

65 Demolito 2017-06-18 64-bit 2844 +25 −25 48.5% +7.7 43.9% 481

It is about as strong as Jonny 4.

Considering 2000 lines, that is pretty incredible. It reminds me of thinker, but unlike thinker, it actually produces a PV.

That's the previous version. Current version is stronger than Cheng 4.39 (at least in my 8+0.08, hash=8 testing).

Hi Dann,

Sensational!
Lesser as Thinker?
Do you know how many Senpai have?

Best
Frank
I like computer chess!
