Hello Chess Friends,

Nowadays is popular to discuss about the sizes of chess engines ))

That's why I decided,
To check some of the engines, which mostly of them already participated in SCCT

To be honest,
Size formats are not much important...
I care more about originality, stability, and + Elo performance of course )!

But however, here are the smallest ones,
Note that the list includes engines, which are less than 200 KB:

Hakkapeliitta 2.0 x64 = 26 KB = 2767 Elo
Elf 1.3 = 33 KB = ??? Elo
Counter 1.2 = 47 KB = ??? Elo
Vice 1.0 = 72 KB = ??? Elo
Mskcp 1.45 JA = 81 KB = ??? Elo
Milady 325 = 94 KB = ??? Elo
Requiem 0.53 = 96 KB = ??? Elo
Rodent 1.6 x64 = 96 KB = 2842 Elo
Uralochka 1.1b = 101 KB = 2245 Elo
Diablo 0.51 = 101 KB = ??? Elo
Anatoli 0.35k = 112 KB = 2485 Elo
Nemo 1.01b x64 = 115 KB = 2911 Elo
Sungorus 1.4 x64 = 118 KB = ??? Elo
ChessMaster 9000 = 131 KB = 2664 Elo
Atlas 3.70em = 149 KB = ??? Elo
Scorpio 2.77 x64 = 149 KB = 2863 Elo
Fizbo 1.31 x64 = 160 KB = 2863 Elo
Gull 1.2 x64 = 162 KB = 3023 Elo
Amateur 2.82 = 165 KB = 2369 Elo
DisasterArea 1.54 x64 = 176 KB = 2906 Elo
Frenzee v3.5.19 x64 = 188 KB = 2806 Elo
Adam 3.3 = 190 KB = 2256 Elo

1)Hakkapeliitta 2.0 is the smallest one - My Congratulations to Mikko Aarnos (Finland)
Really impressive...24 KB, this is a World record, if we check originality + size + Elo

2)Elf 1.3 is another very tiny one, created by Erdi Ata Bleda (Turkey)

3)Counter 1.2 is very small too, created by Vadim Chizhov (Russia)

Also I decided to check some well-known IPPO (Rybkanians) ones:
Note: Rybka 3 x64 = 2.875 KB, released date: 29.07.2008
The first Ippolit version is appeared on the scene: May 2009
For example, Ippolit 0080c is 268 KB, released date: 21.10.2009

Thinker 5.4D x64 = 78 KB = ??? Elo
Houdini 1.0 x64 = 271 KB = ??? Elo
RobboLito 009 x64 = 287 KB = ??? Elo
Strelka 5.7 x64 = 287 KB = ??? Elo
Bouquet 1.8 x64 = 447 KB = ??? Elo
Gull R600 x64 = 458 KB = ??? Elo
IvanHoe 999946h6 x64 = 492 KB = ??? Elo
Fire 3.0 x64 = 504 KB = ??? Elo
Critter 1.6a x64 = 546 KB = ??? Elo
Elektro 1.2 x64 = 576 KB = ??? Elo
Naum 4.2 x64 = 658 KB = ??? Elo
DeepSaros eXp x64 = 666 KB = ??? Elo
BlackMamba 1.4 x64 = 887 KB = ??? Elo
Equinox 3.30 x64= 3.882 KB = ??? Elo

Continuing, let me say a few words about these issues...
I am surprised that Thinker is the smallest Ippo one, just 78 KB !! very small size indeed...
And well-done to Thinker's author, this is another talent and record... !)
For example, Thinker seems to the World's strongest engine, if we check the sizes + Elo

And here is Houdini 1.5a vs Critter 1.6a comparing:
Houdini 1.5a x64 = 1.332 KB, released date: 15.10.2011
Critter 1.6a x64 = 546 KB, released date: 26.06.2012
On my Sim testings, I've noticed that both engines are very similar (+60% similarity)
And after checking the rating lists: both engines have almost same Elo performance !)
It seems the author of Critter 1.6a learned/copied a lot from Houdini 1.5a's author !!))
Houdini's author learned/copied a lot from Ippolit's author
But note also that R. Houdart managed to add many Elo points, this is really very important !
Where unfortunately Richard Vida (the author of Critter) could not....!!
Ippolit's author learned/copied from Rybka's author and etc and ets...
But however I should admit also that,
Ippolit's author managed to make his engine to be stronger than Rybka 3 too
Right now I am not sure how much Elo difference exactly...
That's why I started testing Robbolito 0.90 x64 and Rybka 3 x64
The first Ippolit ones are too buggy, that's why I preferred more stable one
And soon I plan to publish the first results....
Please note also that if Robbolito 0.90 will be over than Rybka 3 with +50 Elo
Then I will leave its name as it now (as Robbolito) and if less than 50 Elo,
Then I am afraid that it will be renamed as RybaLito ...
In my eyes, in case of close similarity plus 50 Elo to be over...
Then this engine deserve to be tested under SCCT, and to leave it as original name...

BTW, Fire 4 x64 has the biggest size: 25.257 KB
I wonder, how many engines are inside ?? ))) just joking...
Yes, the latest Fire 4 version seems to be clean, with less than 50 % similarity
Congrats to Norman Schmidt (like Gull 3), Fire 4 is another one, which is already cleaned...
And I hope to see more clean chess engines in the next new releases...
And it will be great if you will be able add some extra Elo points, lets say 50 Elo !)

Please stay tuned...more info coming soon )

Best,
Sedat
