Android UCI engine update: armFish 2018.02.11 to 2018.02.19

ArmFish is a project based on the assembly code to achieve the highest speed with Stockfish engine. A lot of updates have rained during February, so frequently that i thought it would be easier to share them all together, in a single post.

ArmFish and MateFish are provided side by side, bearing in mind that MateFish is a specific version of ArmFish, dedicated to find mating attacks quicker rather than breaking ELO records.

GET armFish 2018.02.11.LA for arm8
GET armFish 2018.02.11.CP for arm8
GET mateFish 2018.02.11.LA for arm8

Rahul, have u tried to open .bz2 by winrar ?
then u will get

which is working both in droidfish +chess tournament
( i have forget to extract previously 😁 now working perfectly )

I alwz mention these 2 apps as some works in droidfish only , but not working in chess tournament ( both means it will work in any gui )

Rahul said...

Thanks Chysiddh, for suggesting me this idea.

Alexei there must be a serious bug in the arm64 version, during analysis of a game the nps jumped from 2500 to 4700 moving a piece, the selected moves were wrong and evaluation from +.29 went to -45 for a move completely wrong that should be over +1

Alexei Chernakoff said...

There is no error.In the engine settings in droidfish, disable the [Analysis Contempt] option.

Alexei Chernakoff said...

I tested Cfish-100318-arm64v8 against Cfish-9 and it plays harder.And the fact that the rating of the engine jumps,it works dynamic contempt.It changes the score depending on the opponent's answer.There is no bug in the engine,this is how the new Cfish or Stockfish works.Check Cfish-100318 against any engine and you will see that it is much stronger than any.

Alexei is smth wrong with settings?

2 test positions. Cfish 15.02.18 solves them faster than 10.03.18.

Also according to android app nps is a bit lower on a this newer vesrion.

Alexei Chernakoff said...

2 positions??This is not enough.We need hundreds of positions (if not thousands) to draw some conclusions.A slower speed is generally not what you said.These are different versions of Cfish (added new patches,they can reduce the speed it add bonuses to the positional game).
You can't compare the speed of different versions of engines.

chysiddh14 said...

tq Alexei
Can u explain all stockfish clone / derivative what they are?

Alexei Chernakoff said...

Cfish is not a clone and not a derivative.This is a pure port of Stockfish in the language c11.
Brainfish is stockfish. with the support of the Cerebellum book.

Unknown said...

Good morning, I thought the default contempt was at first 20. Then it became 18, and now it is 12. Alexei, can you explain why they are slower removing contempt? Thanks

Alexei Chernakoff said...

In stockfish-9 there was contempt=20 but it was static.In new versions of stockfish to cfish set dynamic contempt, the engine, depending on the assessment,automatically adjusts the level of contempt.So don't be fooled by that contempt the default is changed.

I can only appreciate Alexei for compiling into Android

Alexei Chernakoff said...

My compilation Arasan-20.5(arm7,arm64v8).
Changes in Arasan 20.5:
1) Have tuner output objective value to params file.
2) Bug fix in more() function of RootMoveGenerator.
3) Fixes to Syzygy code: enable locking when multi-threaded.
4) Fix very shallow search when MultiPV greater than the number of legal moves.
5) Fix UCI score output when tb hit at root - now outputs score based on tb score
(worked with multipv but not when multipv == 1).
6) Do not exit search for forced mate if UCI and search type is fixed depth or fixed time.
7) Don't execute move after UCI "bestmove" Wait for GUI to send position.
8) Remove Nalimov and Gaviota tb support.
9) Fix mate score output in GUI.
10) Add code to save/restore window flags and state in GUI.
I expect this version to perform pretty much on a par with Arasan 20.4: all the changes are basically bug fixes, not performance improvements. But some of the fixes are significant: in particular, the tablebase code fixes may prevent occasional crashes when running multithreaded with tablebases in use.

Alexei Chernakoff said...

Incidentally, in the analysis mode, the engine is not working properly.It works well only when playing.That's how the author of the engine explained it.
Quote:
at the moment, i don't have an easy fix for this. the engine doesn't respond to stop command, so even if it works, the analysis can't be interrupted. will implement this in future.

Rahul said...

Xiphos playing style is great.it play like Tal & Kasparov who loved sacrifices their pieces to beautify the games including with great tactics,its great.

Thanks Alexei! One question:this s Xiphos 0.1.10 as in the engine settings screen correct? Because when it loads the engine loads as 0.1.11 not 0.1.10.Please clarify the version.Thanks for the engine again!

My English is not good but you can understand.

Alexei Chernakoff said...

Each engine has played to 8 games??It is impossible to understand who is stronger,the error ~(+/-150) Elo!Need hundreds of parties (and sometimes and thousands of).You identified the winner of the tournament, not the strongest engine.

Alex said...

@ karim - Here is results from your test, as Alexey told already, you simply identified the winner of the tournament (with all respect karim, i can't even call this as tournament, i mean 20 games for 5 engines??).. Error bars are 400 + times bigger than elo difference, it means that you need at least 200 games for each engine, not for the whole tournament! Rahul's test is more convincing 75,5 vs 24,5, it shows that Ethereal is a little stronger.
Anyway, karim why don't you use Cfa (Chess for android) app? There is a fast time control, (10sec+1sec) that you can use for more number of games, and more accurate results. Cfa also support pgn opening books, i made some pgn books with a specific number of games, all books contain 8 moves = 16 ply, eg if you want to make test Round Robin between 2 engines and 100 games, then choose 8moves_v3_50positions.pgn (50x2=100 games).

Hello Karim,

Yes! It's really need to made more games.

And, other thing is that Andscacs not play better better in hawk GUI in 20 to 30 game.

Made more game!

One more thing is that when Xiphos is beaten by senpai and ethereal then how is possible that xiphos beat Andscacs!

Rahul said...

Finally, I get rid off my old 32-bit device, and I bought a new redmi 64-bit device only for chess.

And, my first tournament is against the big rival of each other,
KOMODO vs STOCKFISH,

When, I was going to made this tournament, I was thinking that it is worthless because komodo11 is not updated while SF is always updated with big improvement, and recently SF beat Houdini in final,

So I think SF will beat Komodo badly,

and Yes, SF beat Komodo but not big differences.

Now, I wonder that which improvement SF doing these days, Komodo already had done.
See result!

Hi Rahul, pls tell me which GUI r u using for ur tournaments? And how to set 2 different engines play with each other in typical tournament conditions. I mean the hole process to make a successful tournament in an Android device. By the way I have Mi Max with 64 bit processors and 3 gb RAM.

P.s.. I meant CFA, not CPA..

Rahul said...

For tournament use "Chess for android" from play store.

Rahul said...

Hi Karim!
Don't get angry.



Would you please make 50 games in hawk GUI between xiphos and Andscacs and see result.
Then you will get the answer.

I can't set up the tournament effectively. Pls explain the whole process. It will help me a lot.

Karim said...

I get never angry, for you I'll try

Hi,
First you must have "Cfa" and give the app permission for storage by going setting's installed app.

Now,open the CFA and tap on the black screen, a pop-up menu will appear then choose uci and xboard and tap that an another menu will be open then choose "install engine SD card"and after that choose folder in which you have chess engine and select engine and install.

And, for tournament you will have to tap again UCI & XBOARD
Option you will get tournament option.

try chess tournament by javiolo

Yeah thanx. But I know all these processes but after taping tournament option it shows me all the installed engines in a menu and when I chose 2 engines then nothing happens, actually I get no option to begin tounment after that. This is the main problem I am facing for quite a long time and I can not figure out how to begin the tournament after this last engines selection process. Very much annoying for me.

Will you stop arguing!Any plans for tournaments this CFA.All others have a bug and are not suitable for testing,as they give incorrect results.For example,in a good shell Chess Tournament has a bug, it often makes a decision about a draw when one of the engines has a win.In Hawk Chess, an unsuccessful GUI (slows down) consumes a lot of resources and not all engines work in it.CFA is still out of competition.

Hi Rahul! Thanks for the pgn file, you did over 6700+ games, that's nice!
But, i have bad news for you. First, i separated from your pgn file tournament between Komodo and Stockfish, and i didn't look at all about engine lag or flag etc.
Later, taking a closer look at the games, i noticed something very strange, both engines had resignations for unknown reason, there was also time flag (photo->) https://postimg.cc/image/k92660yjp/ Honestly, i haven't seen this type of issues before and i don't know what to say, almost half of your games ended with this way.
Try to change your adjudications rules, give some extra "GUI time lag", and check the device's temperature (it is also important). Last thing, for 10sec+1sec time control set hash 16 or 32, and reset Komodos setting to default.
Later i'll remove all the "corrupted" games, and i'll post your results.
P.S I use this rules-> https://postimg.cc/image/vlernuwyt/

Results from my test - Critter 1.6a arm5 vs Xiphos-0.2, even with more games, elo gain remain the same..

Alex said...

Sorry, Critter 1.6a arm5 vs Xiphos-0.2.2

Rahul said...

Hello Alex,

Would you please check this pgn,in this pgn 300 games Komodo Vs SF.

https://drive.google.com/file/d/1hoeqlX0DGgi1ar3OuQCqZanf7qwvqIU5/view?usp=drivesdk


I think something is wrong, you must check first 4 game and game 40 and after that game from 222 to 250.

I am unable to explain, so please check and tell me what is wrong.

In any one game(I don't remember which one) K won in only 9 move and sometimes in under 26 move. how it's possible against SF?

Alexei Chernakoff said...

Try this compilation cfish-210418-arm64v8 ,build clang-5.0(should now work at all).
https://app.box.com/s/0anykol1bnwxfaub8xl4rk0dgkcfj41n

Rahul said...

It's faster than SF work nice.
Thanks!

Alexei Chernakoff said...

Hi friends.Please, from whom processor Snapdragon and Exynos ,check this version of Cfish(very need) and write works or not.
Thank you for your help.

https://app.box.com/s/jpbz6gx4i2nwii7n4e3lpaw6ccwl7voi

Rahul said...

Yeah it's work nice. I have Snapdragon425 processor.

Alex said...

Yeah Rahul, definitely something is very wrong. In your last pgn, about 70% of the games ended in few moves, or in middle game, game 1-13 "time control flag", game 14 ended normally, from game 15 again "time control flag" etc. -> https://postimg.cc/image/zax7r3tjx/ - https://postimg.cc/image/l4hgvwl9p/ - https://postimg.cc/image/568r5tgrx/ etc..
I have a feeling that the engines don't have time to response, and they lose in time. What can i say, this is maybe GUIs or engines fault, or bad responding from your device. Btw you use arm8 engines, correct? I use arm7, my arm8 device is not available right now (maybe from next week). So, with arm8 engines only Aleksey can help you (or somebody else with 64 bit arm8 device)!

Works fine on Snap 835

Alexei Chernakoff said...

Thanks!

Paulzzz said...

It's nice to be back here,thank you very much Sir Alexei for many engine updates including new engines(Xiphos and Delocto).Although Xiphos 2.2 is very buggy as DroidFish always says"engine error".

Btw,Alex how I can use your pgn book in CfA? I've downloaded it.Thanks��

Alexei Chernakoff said...

My compilation Ethereal-9.64(arm7.pgo,arm64v8):

Karim said...

Alex! Can you share the same books in bin file format? Or how to convert them to bin format?

Karim said...

Rahul, the bugs in your pgn games are because of Komodo engine. You are using the engine Komodo apk version, right?

Rahul said...

Thanks sir!

Rahul said...

Yes,I am using an APK file.

But,what you say about this?
Check! Game 30 and others
https://drive.google.com/file/d/1qjXW2rsGy0sFuj8QTP7XNpg39zQyrSa3/view?usp=drivesdk




Rahul said...


Any solution for this problem?

Check this too, Game 10 and other

https://drive.google.com/file/d/1blMholKSDQ-Sk4Ou9Kt04gtUxpaekuVR/view?usp=drivesdk

Rahul said...

Hello sir,
what is ethereal arm64 gcc?

Karim said...

Remove the apk engines from CFA GUI, I hope the error may be solved..if not then ask Alex, he is more expert in such cases..

Anonymous said...

I had the same problem with Komodo 11.2.2, it has a tablebases bug, if you're using Syzygy tablebases - disable them

Alex said...

Paulzzz - It is very easy, just keep the books on your device memory or SD card and follow the next steps -> press UCI and Xboard -> https://postimg.cc/image/71hy4dmj9/
===================================================================================
Rahul, 2 last tips for you..
1) Unmark animate option -> https://postimg.cc/image/3vxce9r39/, It is marked by default, and this option slows the sending of engine responses to the shell (GUI).
Make small test, about 20-30 games, after that look those games in Droidfish, or in other app, go to the end of the game and look how it's ended. You can also open pgn file with notepad or Code Viever app, you'll see this-> https://postimg.cc/image/irvvlx7np/
2) If the problem remained, then send email with pgn games to Aart Bik.
Good luck!
