Arasan 19.1

[jdart]

Arasan 19.1 is available from http://www.arasanchess.org.

Changes in Arasan 19.1:

Code: Select all

 1) Change/fix root move reordering. After wide search phase, just move
    the pv move first and other moves down.
 2) Scoring change: limit range of KING_MOBILITY_ENDGAME array.
 3) Add scoring for threats of lower-valued pieces and pawns against
    higher-valued pieces (previously only pawn threats were scored).
 4) Add support for thread affinity via the hwloc library (not enabled
    in the release builds; must recompile from source to get this).
 5) Add restrictions on SEE pruning: don't prune evasions, and only prune
    checking moves if they are not discovered check.
 6) Change extension logic: extend checks if not losing or if discovered.
    Other checks can be pruned (SEE pruning) or reduced. Remove FORCED2
    extension (2 legal evasions).
 7) Pick up en passant fixes from Fathom library.
 8) Add fixes for Android compatibility (although note: Makefiles still do
    not support Android cross-compilation).
 9) Fix bugs in Syzygy probing to avoid non-progress in endgames where
    a repetition has occurred.
 10) Non-POPCNT builds use a better software POPCNT implementation.
 11) Change IID conditions: allow IID in check if in PV. In non-PV node,
     score must not be too bad (like Protector).
 12) In "wide" search mode do not shrink upper bound of search window.
 13) Small changes to LMR reduction formula.
 14) Fixes to terminate multithreaded searches faster when fail-high
 detected.
 15) Changes to draw score calculation when ratings are available and
 to logic for "accept draw."
 16) Fix MVV/LVA calculation for move ordering.

Plus as usual book updates/fixes.

A test against 19.0.1 (3000 games at 5 min. + 3 sec, 8 move book, 1 core, no ponder):

Thanks Jon.

Hi Jon,

if I edit a position (Shredder Classic GUI) ...

Example:
White: Kh1, Nh2, Bh3
Black: Kh8

Arasan will not used endgame tablebases if I start the calculation.
Not important what I select out (Nalimov, Syzygy or Gaviotabases).
Not important what I set in Arasan.rc

Only if I switched to Nalimov without to create a new eng file ...
Example: From Gaviotabases to Nalimov ... Arasan find directly the mate and I can see TB=22

Try it out ...
Set the same position and start the analyzes.
Arasan calculated with around +7 without to find the mate.

Hi Jon,

1.
I can set in UCI Options (Shredder Classic GUI)

A. Path for Gaviotabases
B. Path for Sygyzy

I can't set the path for Nalimov (not logical)

2.
If I set Tablebases = Nalimov
I should see that in the *.eng file or it's not Logical too!

All what I can see is ...

Code: Select all

[ENGINE]
Name=Arasan 19.1 POP x64

Filename=C:\Chess\Shredder_12\Engines\Arasan\Arasan_191-POP-x64.exe
[OPTIONS]
GaviotaTbPath=c:\Chess\_gaviotabases
GaviotaTbCache=32
SyzygyTbPath=c:\Chess\_syzygybases

And I can't see what Arasan do now!
Better is ...

Code: Select all

[ENGINE]
Name=Arasan 19.1 POP x64

[OPTIONS]
Tablebases=Nalimov ... should be to see here
NalimovTBPath=c:\Chess\_nalimov ... should be to see here
GaviotaTbPath=c:\Chess\_gaviotabases
GaviotaTbCache=32
SyzygyTbPath=c:\Chess\_syzygybases

And I know ...
Tablebases = Nalimov
TBPath= c:\Chess\_nalimov

Much better ... maybe this is the mistake I wrote before.
I think Arasan can't find any of the endgamebases because engine don't have the order what should be used because ...
Tablebases=Nalimov is missing ...

Maybe this one helps for the bugfix.

The Nalimov UCI options are there. This is the console output after "uci":

I don't know very much about Shredder but it looks like from docs it assumes that the tbs in use are Nalimov and there is a GUI dialog to set the path (http://download.shredderchess.com/pc/sc ... Manual.pdf). What it sends to the engine though I don't know.

Hi Jon,

that is right what you wrote.
Sorry I forgot it ... (nalimov path in Shredder GUI).

But why it works fine with Arasan 18.3 (with the position I gave as example) and not with Arasan 19.1? Arasan 18.3 gave directly the mate if I start the analyses.

Arasan 19.0 and 19.0.1 not checked from myself.

Too late ...
I will looking tomorrow with more time in detail but I try it out in the night around 1 1/2 hours with all what is possible to set with sygyzy, gaviota and nalimov bases in combination with *.rc and without *.rc file.

Maybe I should try the winboard mode.
This one I can try out tomorrow. Maybe with a winboard configuration and wb2uci it works fine under Shredder GUI.

Best
Frank

Here you can see it ...
Version 18.3 and Version 19.1 ...

Maybe this one ...
I switched the engine only and make no changes!
Means from 18.3 to 19.1 ...
