Guys,

I've never been far from you. I've been reading every comment and all your shares all the time.

Indeed i'm late recovering from the hiatus of the blog. But note that i'll be coming back very soon. I'm alive and kicking!

Keep up following.

The return will be good enough for you to forgive the long lasting silence.

Best wishes to all.

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.

Android UCI engine update: CT800 1.20

CT800 is an average level engine released by Ratmus Althoff who recently concentrated on compiling for Android and finally managed to obtain working binaries.

CT800, in fact, was born as a dedicated chess computer idea and it was designed by Rasmus Althoff.  The original CT800 featured an ARM Cortex M4 microcontroller of an Olimex H405 board that operates up to 168 Mhz, with 1 MB of flash memory, 192+4 kB of SRAM, and multiple I/O and USB connectors, with a 4x20 character text display, two leds, and a 4x4 + 1 keypad as peripherals aka user interface. Voltage source is due to four NiMH rechargeable AA batteries or external 5 V DC power supply.

The "chess computer" CT800

CT800's firmware is developed by Rasmus Althoff, released under the GPL Version 3. The chess playing software is an ARM port of George Georgopoulos' open source engine NG-play including a KPK bitbase by Marcel van Kervinck.

Chess Tactics & Strategy aka PbChess

This is nothing but PBchess ported to Android by the developers. As per a comment sent to Chesstroid, i came back to analyze what engines they embedded. There's nothing new. Two engines out of three are previously shared builds of Fruit and Toga. Regarding Stockfish, although it looks like different, smaller in size, doesn't bring too much attraction after SF9. Therefore, the app is only recommended for its basic features, not the provided engines.

The app description from Google Play says:

Zevra is a weak engine written by Oleg Smirnov, around 1700 in Rapidroid scale. The Android build still causes issues on my devices, like the previous 1.4 version: A remarkable % of the games played with black by Zevra needs to be replayed after a division. I keep hoping Alexei can find the trick behind this problem with Chess for Android.

However, you can always try Zevra with Droidfish or for human vs machine games in CfA.

Android UCI engine update: Stockfish 9

The long awaited ninth fish was finally released after TCEC-9, thanks to latest fruitful patches adding the utilization of the contempt factor. This number defines how positive (or negative) the engine will interpret its evaluation. More contempt means more optimism and less contempt means more desperation for an engine. By definition, contempt factor can convert draws to wins against a weaker engines but it can also cause losses instead of draws, while forcing for a win.

By the end of Janary, the official SF9 has been released on Stockfish website. It has included Alexei Chernakoff's Android builds that i share below. The choice of the Stockfish team made us extremely happy and proud of what he achieved.

GET Stockfish 9.ACH (OFFICIAL) for arm7 (Jan-31th, CRC32: 23404375) and arm8

After first tests, arm7 build has been found to perform worse than expected due to incompatibility between latest patches and heavy PGO+LTO optimizations used by the compiler. Arm8 builds were healthy but arm7 delivered less than +60 ELO vs SF8.

Therefore, following alternatives came quickly in a few days during first week of February.

GET Stockfish 9.ACH for arm7 (2nd build on Feb-2nd, probably without PGO/LTO, CRC32 = D38AD094)
GET Stockfish 9.ACH for arm7 (3rd build on Feb-2nd, fixed PGO, CRC32 = 251627CA)
GET Stockfish 9.ACH for arm7 (4th build on Feb-7th, noPGO?, CRC32 = 25D1EE16)
GET Stockfish 9.ACH for arm7 (5th build on Feb-7th, fixed PGO, no LTO, CRC32 = 65FEB516)

I'd already chosen the 3rd build for Rapidroid before the 4th and 5th came out and didn't change it afterwards because it had played a lot and its performance was satisfying (+60 to 90 ELO depending on the progression of the rounds). So, it's up to you to decide which one suits you best.

One thing is sure: More nps didn't mean higher ELO this time.

SSDF rating list of 20-Jan-2018 featuring Stokfish 8

Happy to see that SSDF featured SF8 instead of SF6, at last. The bad news, on the other hand, is that SF9 appeared shortly after SSDF update came in. Well, bad luck...

Another bad news is that Houdini is still completely missing, probably due to the fact that P.Houdart didn't want to lend a free copy of his program. This is not written anywhere, just my guess.

The Top-30 of SSDF list

Comments to the Swedish Rating List 1/2018, January 20

"On our latest ratinglist we have a new leader! It's the Stockfish 8-program by Tord Romstad, Marco Costalba and Joona Kiiski. As the program is released without an own book, we have used the free opening book from Fauzi Dabat, called "Aggressive 3.2 by Fauzi.abk". Even though it's early on, this strong combination has achieved an impressive rating of 3436 after the first 202 played games! This is 37 points above Komodo 11.01 on second place, but we will of course need to play more games to be able to shrink the error bars.

Another early bird is the Komodo 11.01-program by Larry Kaufman and Mark Lefler, which we introduced on our Ryzen-hardware last time around. We now have enough games to present an early rating for it on our Q6600-level. With a rating of 3340 after the first 202 games, it still trails its older 9.1 program by 13 points. This relationship will probably be readjusted for the next list as more games are played.

Since last time we have also included our formerly tested Wasp 2.01 by John Stanback on both the Q6600 and the Ryzen 1800X hardware. On our Q6600 it has reached a rating of 3068 after the first 320 games, and on the Ryzen hardware it has achieved a rating of 3155 after 446 games. As we also have tested it on our 32-bit, singlecore A1200-level, we can now compare it on three different levels. Judging from our testing, it seems like the difference is approximately 100 rating points per hardware level for this program.

Compared to our former ratinglist, Millenium ChessGenius and Deep Hiarcs 14 1800X gained 10 respectively 9 points. Wasp 2.01 A1200 lost 21 points, Deep Shredder 13 1800X lost 11 and Komodo 11.01 1800X lost 8 points.

The next ratinglist will be released as soon as we have enough games to be able to present one or more of the manually tested chess computers which we test at the moment. They missed this list by a small margin, but hopefully we will be able to present them in our next ratinglist which we hope to release in March/April.

Lars Sandin"

Android UCI/XB engine update: Wyldchess 1.51

Wyldchess is a UCI and Chess Engine Communication Protocol compliant open source chess engine by Manik Charan, licensed under the GNU General Public License v3.0, written in C/C++, first released in October 2016. Origin of ideas and implementations are documented inside the source code, e.g. tapered eval SIMD score or SEE from Stockfish. Since version 1.5, released in June 2017, WyldChess supports Syzygy Bases.

The update to 1.51 is not new and i must have skipped it somehow. There's only one build available,  compiled by the author. Unfortunately, it crashed on my devices the same way as v1.5.

If you can run Wyldchess on your device without issues, share the recipe here.

Life is a Game of Chess

December and January were full of bad surprises in my life. It just reminded once again that life is a chess game too, more or less complex, where you have to protect your valuable pieces from the other color and to achieve this, you may have to sacrifice some of the other pieces to survive.

No matter what number of squares are present on the board, it's a game that begins and ends for a purpose.

Despite all difficulties, i hope i can continue to allocate enough time to keep this "still unique" blog alive and kicking, in near future because it proved to be worth the effort.

This January of 2018, Chesstroid has reached 500.000 hits after 3 years without any artificial support or sponsoring. Today i'm proud of what it has become. To be honest, it's gone way beyond what i'd imagined in the beginning.

Thanks for all those who supported. You're all amazing...

3 more articles about Kasparov-Deep Blue and AI

If you are not old enough, you didn't see the days when a world champion could beat dozens of best computer chess programs even in a simul.

In 1997, the equilibrum has shifted in favor of the computers, after Deep Blue has been the first computer to beat a human world champ in a match.

The 6 game match is a historical moment of the human vs machine, so there have been many books & publications & media articles about it.

Let me share two of them, although not very recent, but still interesting to read:

1) @ THE CONVERSATION:
Twenty Years on from Deep Blue vs Kasparov: How A Chess Match Started the Big Data Revolution

2) @ TIME MAGAZINE:
Did Deep Blue Beat Kasparov Because of a System Glitch?

3) @MEDIUM.COM: CONVERSATIONS WITH TYLER COWEN (BONUS PACK):

...and the third, as a bonus, speaks about the future of AI from Kasparov's point of view. Don't forget to read what GK suggests about a match opportunity between Magnus Carlsen and the strongest computer program available (Stockfish?).

Android UCI engine update: armFish 2018.01.21

armFish builds used to be made by Lyudmil Antonov for arm8 64-bit devices only, using direct cpu instructions via assembly language. This method is the most native but a little bit unhuman too. One would only bear for nothing but to reach for the the fastest build.

The assembly project seems abandoned by Mohammed Li, the former implementer of the code for Windows and Linux. The project is now forked and continued by Michael Byrne, developer of derivatives like McBrain, Hawkeye.

The Android port shared below comes from Alexei1976. We can do nothing but thank him for the contribution.

RAPIDROID RELOADED: January-2018 ft Komodo 11.2.2 and Andscacs

Here i come with a new list for a new year, long awaited and delayed a little bit due to unexpected updates that i couldn't ignore. Especially Andscacs, Ginkgo and Ethereal.

It's a pleasure to see new stronger engines coming to the stage, like Andscacs and Ginkgo thanks to Alexei Chernakoff's valuable efforts. As previous top engines didn't perform the same way against newcomers, we have a slightly changing distribution this time, explaining why Stockfish lost ~50 ELO. In fact it didn't lose anything, it just traveled between the lines. ELO margins between this list and the previous one are still linked.

I think this update is the most accurate ever because there are more games per engine and more competition at the top. Conclusion: Different population explain different distributions and different distributions explain different ELOs.

If you ask why Stockfish 8 is still here, there are two reasons:
1) There's no SF9 coming, not enough improvement yet,
2) Komodo is still behind.

The highlights of this release:
* ADDED Andscacs 0.921 (3210 ELO)
* ADDED Ginkgo 2.0 (3146 ELO)
* ADDED Sctr 1.0 (2722 ELO)
* UPDATED Ethereal 8.16 to 8.37
* UPDATED Komodo 11.01 to 11.2.2
* UPDATED Scorpio 2.7.7.JA to Scorpio 2.7.8.ACH
* UPDATED Sting SF 8.1 to 8.9
* UPDATED Senpai 1.0 JA to Senpai 1.0.APE
* UPDATED Texel 1.07a9lazy to 1.08a4
* UPDATED Vajolet2 2.3.1 AP to 2.4.ACH
* UPDATED Zurichess Luzern to Neuchatel

Targets for next release:
* ADD Gogobello 1.4
* UPDATE Arasan 20.0 to Arasan 20.4
* UPDATE Fruit Reloaded 2.1 to 3.2.1
* UPDATE Ethereal 8.37 to 8.85
* UPDATE Senpai 1.0 to 2.0
* UPDATE Texel 1.08a4 to 1.08a8
