Andscacs - New version 0.872

Post by cdani »

I just published a new version of Andscacs, 0.872:

http://www.andscacs.com/andscacs0872.zip

It's the one playing at TCEC stage 3.

Changes:

* Improved various evaluation parameters.
* Solved little bugs.
* Improved pawn evaluation.
* Improvements on king safety.
* Speed improvements.
* Improved time management.
* Improved some endgames.
* Improved move sorting.
* Improved imbalances.

Is not much better than 0.871, maybe 5-10 elo. From 0.86189 that played at TCEC stage 2, maybe 15-20, I'm not really sure.

I will explain in detail in the programming section the changes from 0.86. I don't expect it to go to TCEC superfinal :-)

I don't plan to publish any new version soon.

We expect Anscacs be at least #4. Next year at least #2 and within two years #1.

Otherwise we will be extremely disappointed.

:-) I think this will be a little difficult.

I forgot to mention that this version is already playing in Division 1 of Graham:

Thanks Daniel! You're definitely a solid #2 in Graham's D1. :D

Excelent Daniel!!!

I've tested this version with this position

[d] q2k2q1/2nqn2b/1n1P1n1b/2rnr2Q/1NQ1QN1Q/3Q3B/2RQR2B/Q2K2Q1 w - - 0 1

and andscacs.exe crash

Andscacs finished 6th in stage 2, so it's a little improvement.

Andscacs now #7. Big difference between first four or three and last four. Houdini is back.

improvement of Andscacs has been extraordinary.
When Daniel polish some details, will be more up.
How I have read in the chat their efforts of tests are many, makes lack many good computers to try all the ideas.
It is difficult.
