Today, Rybka 2.3.2a mp passed Deep Fritz 8 to move into the fifth spot on the list of engine popularity in the Playchess room, as given at http://www.playchess.com/stats/engineranking.htm

Of course, Rybka has so many different versions that there is no chance of getting to the top of the list unless Vas retires for about eight months.  Thus, I thought it would be an interesting project to add up the number of games played by the different engines.  Of course, many games have the same versions of the same engines playing (hence their "total games" number at the top of the page being only somewhat over half of my "total games" number), but I don't believe this affects the relative popularity of the various engines (after all, Deep Shredder 9 was always playing Deep Shredder 9 in 2005).  Anyway, here are the results.  It seems that Rybka has more games than all of the other engines combined!

Interesting that the #1 ranked engine,   rybkav2.3.2a.mp.x64, is in 174th place...

There is no engine that actually has that name.  Someone renamed the engine to the execution file.  With probably only a few machines using the engine being renamed in precisely this way (as opposed to one of the other 160 things that people have renamed their Rybka engines), you can expect a low placement.

I think they should have some kind of code that organizes all the identical engines together. Or can any engine have any name? That kind of makes "popularity" a bit useless... (Not to mention I think Rybka should be #1 on popularity...)

I could buy a 16 core machine and install Zappa Mexico on it, with an uberbook, and start beating everything then claim that I'm using a new Deep ProDeo 1.6 with a private personality and nobody (But Ed) would be able to prove I'm lying? I hope this is not the case...

Actually, you can do exactly this :-)

Any Winboard or UCI engine can be renamed to anything you want.  You could even screw things up for lots of people by renaming it to the name of some other engine that's already in existence, such as Deep Fritz 7, thus tempting everyone to think that Deep Fritz 7 must suddenly be really good again on this new hardware that people have.

Or Rybka 2.1d3. We need that myth. :)
