The Battle of the Crowns has finished!
(Or, as Bruce put it 'The Championship of Dann Corbit's Basement'!)
;-)
One Crown Division Final Standings:
Program Score % Av.Op. Elo + - Draws
------------- -------- ---- ----- ----- --- --- -------
1 TSCP : 30.0/ 36 83.3 2275 2555 83 155 22.2 %
2 Monik : 25.0/ 36 69.4 2289 2432 96 146 11.1 %
3 Storm : 21.5/ 36 59.7 2297 2365 107 112 19.4 %
4 Noonian : 21.0/ 36 58.3 2298 2356 109 78 44.4 %
5 Ozwald : 19.5/ 36 54.2 2300 2330 115 104 19.4 %

8 SnailSCP : 10.0/ 36 27.8 2320 2154 129 93 22.2 %
9 Raffaela : 9.0/ 36 25.0 2322 2132 135 90 22.2 %
10 Golem01 : 5.0/ 36 13.9 2335 2018 237 81 5.6 %
Notes, surprises, and ruminations:
I expected TSCP to finish first, and it did (in a dominating fashion). Golem01
is declared the "most playable" program on earth for beginners. That is not
because it finished last in the 1-crown division. Rather, it is because it never
crashes and won't be terribly intimidating for chess amateurs. I like all the
programs in the contest, including the 'cellar-dwellars'
;-)
Two Crown Division Final Standings:
Program Score % Av.Op. Elo + - Draws
------------- -------- ---- ----- ----- --- --- -------
1 Freyr : 31.0/ 44 70.5 2292 2443 84 130 13.6 %
2 Cilian : 30.5/ 44 69.3 2293 2434 85 131 11.4 %
3 Sjeng73 : 30.0/ 44 68.2 2293 2426 86 117 18.2 %
4 Faile : 28.0/ 44 63.6 2296 2394 91 102 22.7 %
5 Averno : 25.0/ 44 56.8 2301 2348 99 93 22.7 %
6 SSEchess : 24.0/ 44 54.5 2302 2334 103 90 22.7 %
7 Gully2 : 22.5/ 44 51.1 2304 2312 108 94 15.9 %
8 ColChess : 22.0/ 44 50.0 2305 2305 95 95 22.7 %
9 Chessterfield: 16.5/ 44 37.5 2312 2223 97 92 25.0 %
10 DChess : 16.5/ 44 37.5 2312 2223 123 92 6.8 %
11 NewRival : 12.0/ 44 27.3 2319 2148 126 82 18.2 %
12 Crux : 6.0/ 44 13.6 2331 2011 204 71 9.1 %
Notes, surprises, and ruminations:
Crux is given the title of "Crash King" which also cost it a considerable number
of points. I expect that the current versions of Crux are far more stable than
the version used in the contest. Having a program that crashes all the time
included in a contest like this where many games are run unattended is a big
hindrance. This old version of Crux really should not have been included. It's
inclusion is my fault, and I apologize to the author. Congratulations to Freyr
for the nice victory by the narrowest of margins. I think Cilian would have
benefitted greatly from its recent recompile. It's a big boost over the GCC
version in terms of performance. The new Sjeng versions are massively improved
also. I am fairly sure that Sjeng 8.x would leap out of this crowd.
Three Crown Division Final Standings:
Program Score % Av.Op. Elo + - Draws
------------- -------- ---- ----- ----- --- --- -------
1 ExChess : 32.0/ 44 72.7 2285 2455 82 126 18.2 %
2 ArasanX : 31.0/ 44 70.5 2287 2438 84 106 27.3 %
3 lambChop : 29.5/ 44 67.0 2289 2412 87 104 25.0 %
4 Ant : 25.5/ 44 58.0 2295 2350 98 97 20.5 %
5 InmiChess3 : 24.0/ 44 54.5 2297 2328 103 86 27.3 %
6 Knightx : 24.0/ 44 54.5 2297 2328 103 106 9.1 %
7 GNUChess4 : 19.5/ 44 44.3 2303 2263 89 101 25.0 %
8 Dragon : 18.5/ 44 42.0 2304 2248 97 98 20.5 %
9 Amyan : 16.0/ 44 36.4 2307 2210 90 91 31.8 %
10 gnuchess : 16.0/ 44 36.4 2307 2210 102 91 22.7 %
11 Fortress : 14.0/ 44 31.8 2310 2178 117 86 18.2 %
12 LDBlanche : 14.0/ 44 31.8 2310 2178 95 86 31.8 %
Notes, surprises, and ruminations:
I predicted the first and second place entries but the 3 crown division was
closely contested like the two crown division. Also, this ExChess version was
still 3.14. The new 4.x ExChess is DEFINITELY a 4 crown engine -- maybe even
above the centerline in that lofty atmosphere.
Four Crown Division Final Standings:
Program Score % Av.Op. Elo + - Draws
------------- -------- ---- ----- ----- --- --- -------
1 LGoliath : 37.0/ 52 71.2 2289 2445 76 99 26.9 %
2 Crafty : 32.0/ 52 61.5 2294 2376 85 77 34.6 %
3 AnMon : 31.5/ 52 60.6 2294 2369 86 83 28.8 %
4 Amy : 28.5/ 52 54.8 2297 2331 93 85 21.2 %
5 SOS : 28.0/ 52 53.8 2298 2325 94 82 23.1 %
6 Bringer : 27.5/ 52 52.9 2298 2318 96 72 32.7 %
7 TCBishop : 27.0/ 52 51.9 2299 2312 97 73 30.8 %
8 Phalanx : 26.5/ 52 51.0 2299 2306 99 74 28.8 %
9 Comet : 24.5/ 52 47.1 2301 2281 62 96 44.2 %
10 Gromit3 : 24.5/ 52 47.1 2301 2281 79 96 25.0 %
11 Gromit2 : 21.5/ 52 41.3 2304 2243 89 88 21.2 %
12 Francesca : 18.5/ 52 35.6 2307 2204 102 82 17.3 %
13 Yace : 18.5/ 52 35.6 2307 2204 87 82 28.8 %
14 ZChess : 18.5/ 52 35.6 2307 2204 108 82 13.5 %
Notes, surprises, and ruminations:
I am surprised that Little Goliath won so handily. I really thought that crafty
would run away with it, despite not using pondering. However, a 1-3 spanking at
the hands of AnMon really ended crafty's chances with 3 rounds to go. Up until
that point, crafty was leading.
It's a little ironic that the three programs in a dead tie for last place are
also three programs which have had huge upgrades in the recent days.
Look also at the finish of Bringer and Amy! The version of Amy run in this
contest was before I got the Intel C++ compiler, so it is probably lacking 20-30
ELO from that cause alone.

Final notes:
Running this contest was an enormous amount of work, but I am very glad of it. I
had a huge number of enjoyable hours watching the programs battle. All
contestants are worthy competitors, and every program that participated is a
testament to the excellence of its author. It is no simple task to write an
operational chess program. My great thanks to all who have worked so hard to
write chess engines and then had the bodacious spasm of graciousness to release
it for free consumption by the public.
Above all, I am a fan.
