by Marco Costalba:

"Me and Joona decided to release SF 8 with the same sources that will partecipate in TCEC superfinal.

We think it is a sensible choice that makes SF 8 a well defined point in time release, not just a random commit.

In the following hours Daylen will update our official site.

Kiran will kindly compile the target binaries."

The new Stockfish 8 has just come out, and can be found here

https://stockfishchess.org/

So now it looks as if we may have new Stockfish and Houdini engines in the TCEC final, should be an interesting event, assuming some poor
mental retarded person keeps away. clap thumb up

We also have a new Komodo 10.2 out too.  Happy day's !  bigsmile

Well I guess we can assume that the Stockfish 8 and Houdini 5 will go into the list higher than Shredder , which will push it down even more.  However I have used (and like)
Shredder in the past, the only and main drawback is that it is not cheap, plus you have to buy the whole package, you cannot get just the engine.  At least that was the case
years ago, they may sell the engine on it's own now.  But as I said it was never cheap to buy.

in fact I also think that the price is really excessive.

What is the difference between popcnt and bmi2

descriptionStockfish 8 EmptyRe: Stockfish 8

more_horiz
popcnt: Population count is a procedure of counting number of ones in a bit string. Intel introduced instruction popcnt with SSE4.2 instruction set. The instruction operates on 32 or 64-bit words.
bmi2: Bit Manipulation Instructions Sets (BMI sets) are extensions to the x86 instruction set architecture for microprocessors from Intel and AMD. The purpose of these instruction sets is to improve the speed of bit manipulation.
There are two sets published by Intel: BMI (here referred to as BMI1) and BMI2; they were both introduced with the Haswell microarchitecture.

bmi2 is in essence an extension of further speeding up popcnt SSE4.2 with Haswell architecture and later.

Stockfish 8 SE (Special Edition) - a fork of the Official Stockfish, has some features and functions that are not part of the official Stockfish source. Many of these changes were derived from the Stockfish team from pulled requests which were not committed , but which were interesting to me and subsequently incorporated in this unofficial fork of Stockfish.

As one can note above, none of these changes appear to be detrimental to Stockfish playing strength. New in this update , the "study" option from SF Matefinder by Joesph Ellis was added - based on some of the posts here , many of you should enjoy this option. So when one is looking at a position you can quickly get a second opinion without reloading an engine , just check the uci menu box for "study" and you are on your way. Also added the "Clean Search" uci option from Ellis' Matefinder. The "fast play" when mate is found is now a uci option, by default it is turned on. If you want SF 8 SE to keep searching for a shorter mate , check the uci "fast play" menu box off.

And naturally, this has the other features from previous forks, including Multi-PV when using tb's (submitted by Ronald de Man) , the uci menu option "throttle" to simulate a slow pc from the 90's, select elo engine strength from the uci menu, which utilizes the 40 different skill levels ( official SF has 20 skill levels) and the fast play when mate is found mentioned above.

One can check out the "study" option from the command line "setoption name Study value true" and then type bench - the bench nodes will be significantly higher. On any position , this will provide a different perspective and, sometimes, a very interesting "second opinion" - very nice work by Joseph Ellis.

Stockfish SSE 8 Android Chess Engine
Stockfish SSE 8
Stockfish 8 SE is the Special Edition of Stockfish as described here:
http://talkchess.com/forum/viewtopic.php?t=61952

So one might be wondering what is the SSE version? Back in the 80's, Pontiac came out with a Bonneville SE Edition model , but then when they came with a newer "top of the line" model Bonneville , it was the "SSE".

SSE incorporates Brainfish - more information here: http://www.zipproth.de ) , essentially, a deeply searched database of chess positions at its disposal. I created an opening based book on WCC games (available here http://talkchess.com/forum/viewtopic.php?t=61999), knowing this would give Stockfish a huge advantage against an opponent that did not have access to the same database.
