Hello, everyone!

I'm happy to release a new version of my engine, zurichess glarus.

The source code for this release can be browsed from https://bitbucket.org/zurichess/zuriche ... ase.glarus
The release binaries can be downloaded at: https://bitbucket.org/zurichess/zurichess/downloads
Linux AMD64 https://bitbucket.org/zurichess/zuriche ... inux-amd64
Windows AMD64 https://bitbucket.org/zurichess/zuriche ... -amd64.exe

Since last release
* Improve futility conditions. Geneva's futility is a bit too agressive and causes lots of tactical mistakes.
* Add History Leaf Pruning similar to https://chessprogramming.wikispaces.com ... af+Pruning.
* Improve pawn evaluation caching. Also cache shelter evaluation.
* Improve king safety using number of simultaneous attackers.
* Improve time control. Timeouts should be extremely rare now.
* Small tunining of LMR and NMP conditions.
* Micro-optimize the code for the future Go compiler.
* Move Position.SANToMove to https://bitbucket.org/zurichess/notation
* Move Polyglot hashing to https://bitbucket.org/zurichess/polyglot
* Usual code clean ups, speed ups and bug fixes.

glarus is about 80 Elo stronger than geneva in self-play. The later, geneva, has 2473Elo on CCLR 40/40 and 2323 Elo on CEGT 40/4. Self-play is usually a poor estimator of the strength improvement.

Code: Select all

   # PLAYER            &#58;  RATING  POINTS  PLAYED   (%)

   2 stockfish-6-15    &#58;  2324.6   434.0     800    54
   3 glarus            &#58;  2300.5   600.5    1200    50
   4 geneva            &#58;  2215.2   283.0     800    35

This is the same version that played in HGM's tourney yesterday. As usual the source code can be found at https://bitbucket.org/zurichess/zurichess/overview . The latest development Linux AMD64 binary can downloaded from drone.io
https://drone.io/bitbucket.org/zuriches ... /zurichess

Please test the new version if you maintain a rating list.

Regards,
Alexandru
