Stockfish 8 SSE (Special Edition)

[h1a8]

Is this version of stockfish supposed to be stronger than stockfish 8 (or the latest version)?

If so then can someone please give me detailed instructions on how to install it and use it with fritz 15 (I know how to install regular uci engines in fritz 15).

Thanks!

Somebody else will have to decide - but if you run it with the Cerebellum book, tbe odds are looking it may be.

just really learning Crazy House - this is my best game thus far , using the Ladder rating of 1200 - generally less than 100 nodes ,but keeping skill at 20 ( highest) - also no take backs here ;>). For now using no opening book.

Was in control at move 20, lost my way around move 40, but then came back.

ugh! just did some quick analysis - missed a mate in 2 and a mate in 1 , but like said I'm just getting used to crazyhouse . SF also had several chances to mate me, but due to the weak level, failed to see them.

Amazing ! I just started to play against SF-zh on Lichess yesterday too !
Lost to level 1 then beat level 1 and level 2 :

Michael, please check out the LP code patch. It generates some (non-critical) warning from the compiler, perhaps you could clean them up and incorporate the patch in your code base? I didn't use it for the Variant bins since for some reason it made the POPCNT exec slower than vanilla old x64 (!); maybe you could figure out why it worked for SSE but not Variant.

Thanks very much T for the windows exe, will place them on my GitHub page. Unfortunately, I'm on macOS which does not use LP and it ir=s not something I'm not familiar with.

The latest Windows exe's are now on Github

A triple pack of refreshed SF for macOS exe's - these SHOULD work on most Macs going back the last 5 years - either compiled with clang or included static libraries - please let me know if you see otherwise.

https://www.dropbox.com/s/umhbiturw76bz ... K.zip?dl=1

Includes:

latest developmental SF
latest SF sse version
latest SF variant (crazy house etc)

it's late , will update Github with sources tomorrow ...going to bed

[tpoppins]

I cant get this crazyhouse version to work in my fritz gui ( I am still using a Fritz 12 gui ).

Presumably fritz ( 12 ) gui doesnt support crazy house ?

The only variants Fritz GUIs support are Chess960 (FRC) and Giveaway, AFAIK. Try Winboard instead.

[Rowen]

Thought so. thanks for the answer.

We have updates to both "Stockfish-8-sse" and "Stockfish-8-crazyhouse"

The "Ladder" was granualzied to now offer over 1000 different levels. Virtually every ELO level from 1200 to 2600 will now impact the number of nodes (positions) searched - but still keeping to the doubling of nodes every 100 ELO. The secret is this number "1.0069555500567" - take this number to 100th power , it is almost exactly 2. 1.0069555500567^100 ~= 2. So what that means is that can a unique number of nodes seems for virtually every ELO from 1200 to 2600 , 1200, 1201, 1202 etc. Note at the low levels, some ELOs will generate the same number of nodes to be seen, but once you play t a level over 1500 or 1600 ELO , you will see a very slight increase in the number of nodes searched with an increase of just one ELO ( ~0.69555% increase in nodes for every ELO).

in addition, for more variety of play, you now can select a range of ELO for Stockfish to play with serval new commands, "Ladder Range" (true or false ) "Ladder Lower" and "Ladder Upper". As an example if you set "Ladder Range" to be true (checked) , and select "Ladder Lower" to be 1600 and "Ladder Upper" to be 1800, on any given move it will play somewhere after seeing ~1000 to ~ 4000 nodes - so just like a human, it will play some very good moves and occasionally a clunker but not by weakening the evaluation or search ( other than reducing the number of nodes it sees. All other features previously added are maintained.

We hope the kindness of T Poppins, so that compile us for windows. Thank you very much.

Hi Diego!

We hope the kindness of T Poppins, so that compile us for windows.

There are windows-compiles at Michael's SF SSE- github- link given, you just have to cklick "view raw" to download them

[peter]

Thanks a lot, Michael!
SF SSE seems to use large pages now, doesn't it? Could you please consider to add a UCI- option to switch that off too, like there is one in Brainfish?
Having used Windows for a while you always have to restart it, if you want to let an engine compute with big hash and lp- usage, otherwise lp rather slow down the engine than making it faster
