SmarThink v1.95 is available

[F.Huber]

Seems to work for me. What happens when you run it?

This is what I see:

SmarThink v1.95 [r2300/23.05.2016]

info string Found 0 tablebases.

Well, I have the same output until "Pondering = on", but not the info line about "tablebases" - instead I get the usual Windows error "Program ... doesn't work anymore".
Maybe this is the problem, or it is compiled with any special CPU options which don't work for me (although I can't believe that, because I have a Core2Duo-CPU and run Windows Vista here).
No idea, Smarthink has always run perfectly in the past ...

Have you tried to place values.txt in the engine directory?
Because I'm previously forget to place it in smt195.zip (now it's fixed).
Engine behavior without values.txt is undetermined...

1. Why "Found 0 tablebaes" at first?

I will check it, probably because it tries at first with default path (c:\tablebases).
Is it Arena or other GUI?

Now I start the analyzes ...

Found 0 tablebases.
Found 35 tablebases.

2. Why SmarThink will give not a mate information?

The behavior is probably the same as for StockFish. SmarThink uses TBs to filter out bad moves at the root (i.e. if you have winning moves — all drawish and losing will be filtered out and so on). Then it starts regular search if there are more that one winning move. And it will show mate score only if it will see mate by search.

OK ... I am looking again in UCI Parameter of SmarThink and see this one ...

3. Double entries ...

Still no idea. Is it Arena?

Thank you, Wolfgang!

Please use the latest engine archive (with values.txt that was initially missed).

Hi Sergei,

Shredder Classic GUI

Installed on my SSD under:
c:\Chess\_syzygybases

Oh, your information to mate view ...
Thats explain all!
Thanks!

Again ...
Not Arena GUI, made 10 or more years nothing with Arena ...
since I gave up my work for Arena GUI.

Best

there is a small problem with the webpage (missing css?): download links look the same as text. Thank You for Your engine!

Yes, I've already downloaded the new package, but also the values.txt didn't change anything - it's still crashing.

Hi Sergey,

Is there an ini file for use as a WB engine? Old ini files cannot be used with syzygy.

I think it should work with old ini's.

Actual options are:

TranspositionSizeMb
TranspositionSize
ResignValue
ResignTimes
PawnHashSizeMb
PawnHashSize
Aggressivity
Cowardice
VarietyOfPlay
BookLearningBound
Learning
UseBookLearning
Pondering
UseEGTB
EGTBPath
OpeningsBook
BookLearningMode
UseLearningData
UseBookWeights
LogLearningIntoFile

Major changes:

— Syzygy tablebases support;
— no more Nalimov EGTB support;
— more agressive forward pruning;
— better time management;
— several optimizations;
— further eval tuning.

Estimated Elo gain: +50
