Hello bookmaker

Thanks for the post. Seems to be a strong engine

Wonder if the networks used with lc0 can be used with alpha too

Could you, please inform the link of the engine site?

the engine plays well and uses only the CPU. Unfortunately after about 10 games it crashes and does not go beyond the moves of the book. Strangely, the file is protected with an obfuscator .... I will try to open it with Reverse engineering programs.....

crashes can be caused by syzygy timing (too slow for large files), try if engine crashes change SyzygyProbe Limit from 6 to 5 for both engines in engine - engine testing.

well yes this is based on Sf indeed like any other strong modern engine but its not exactly the same engine,it plays different besides GPL licence which is SF and Lc0 allow change of code so this is no problem.

Here is example after 1200s (20 min) analysis of the same position (startposition) output is as follows

Alpha subZero - NN for CPU Exampl10

if it's the same engine the analysis tree variants after long time will be also the same.SF candidat move after 20 min is 1.e4 Subzero 1.Nf3

here another example (because in startposition is very limited possibilities) in this position SF by 10 mins analyze mostly 1 move Bc1-g5 ,Subzero at this time analyze 3 possibilities Bf4 ,a3 ,Nf5 and even not consider SF move Bg5.

Hash can be set to 0 ,this not using hash only cache which is a type of hash but self allocated.You can change cache size this way
- NN cache size limit --- is max value that cant be across
- ThreadCache multi values min 100 MB max 500 MB

and it works this way
if number of threads x cache multti is bigger than Cache size limit it sets up this limit ,otherwise its allocate via thread cache multi option.

I set it to 36 Lc0 cores (the max for my pc) and I got a whopping 51 nps! Could only reach depth 15 after a few mins. I'd have reached depth 30 in that same time with SF. Something wrong with this engine.

try this compilation its new and should be ok ,but look if you got system 36 threads then you shouldn't set it to 36 but 32 because of 4 cumulative threads ,4 + 32 Lc0 threads = 36.My system is only 24 threads so i test it max on settings 4 + 20 Lc0

you can set number of threads whatever you want but you should set it in this way that Threads + Lc0 Threads should not ecxeed number of threads on your system.
I.e i have 24 thread so max settings i 4 + 20 Lc0.

And what NPS do you get?

I doubt that if I set Threads to 4 and lower Lc0 threads to 32 that I'll get the expected speed. I should've got a lot more than just 51 nps....closer to 51,000 nps.

i get 65 -70 kns on max settings, on fast system you can adjust option OutOfOrder eval to limit selectivity then kn/s should jump a little.

Forgive my question, what does it mean that the other threads are reserved for Lc0? I ask you this because I noticed that the engine requires only the presence in the folder of subzero.zip, libopenblas.dll and client.exe without using them in the least, the engine only shows error if they are not present in folder, but otherwise doesn't use them.
Thank you

Alpha subZero 190.1:  
Code:
https://anonfile.com/1cK6t6Rdnc/alpha_subzero_190.1_rar


I have the other one he released on January 12, 2020, too. It is quite a bit larger due to a Sergio net being included (which it doesn't use as it is supposedly a Stockfish derivative Very Happy ). If you want it, let me know.

Also, supersharp77, I was able to compile a Crafty 25.4y Windows binary. If you still need it, PM me and I will send it your way. I have popcount and non-popcount executables.

I do not know the country of origin and there is no logo that I am aware of. If you happen to find one, please post it on the forum. I would appreciate having it, too.

The chess2u forum has a six page thread regarding this engine:
Code:
https://www.chess2u.com/t13376-alpha-subzero-nn-for-cpu

Here is the other Alpha subZero engine that was released before 190.1  Warning: the VirusTotal report is showing a lot of positives.
VirusTotal report:
Code:
https://www.virustotal.com/gui/file/102189654d874aa1c4616378182b299c6264ae0a3ad4d66a4eac8a3aa4438bc6/detection

Alpha subZero engine:
Code:
https://anonfile.com/LcWaH1Rena/azero_January_12_2020_7z

The executable was packed with UPX in order to obfuscate code and this may be the reason for the positives. I have used this engine in a sandbox and have not detected any suspicious behavior. My Kaspersky Internet Security has not detected any problems. However, please be cautious.  See the chess2u forum link for more on this.

Avast antivirus has a problem with this so I am not risking it at present. I am using an older version which beats them all except Stockfish. Thanks.

Alpha SubZero Chess Engine Empty my best guess as to how it works

Post  jessy on Fri Jan 31, 2020 3:44 pm

The engine saves info to the encrypted subzero.txt file and then forwards the data with the client.exe file.
That is how the real Alpha Zero works except it doesn't scrape your computer's cached memory.

Alpha subzero and bluefish are made by same author and both engines looks at producing faster nodes compared to original versions alpha generates more nodes than original lc0 and bluefish is faster than stockfish. We previsously had asmfish doing the same thing and were these engines stronger than originals. Please author do some useful work and concentrate on either lc0 or stockfish.

So people think and proceed.
