[Computer-go] Lines of code

[David Fotland]

For Many Faces, all engine code is c, and line counts are from wc (includes
blank lines and comments for .c and .h files)

 

today:

The uct/playout code is 10K lines.

The old go engine is 55K lines.  Some of the is code is not used by the
strongest level, but the weaker levels still use the old alpha-beta
searcher.

There are about 2500 playout pattern gamma constants,  about 62K joseki
patterns, and about 2K old program patterns (with 51K move-value pairs).

 

version 10, in 1997, had 42K lines of code

in 2001 the old engine had 53K lines of code

version 11, in 2002, had 52K lines of code

 

The original version 12, 10/2008, had 5.2K lines in the uct/playout code.
This was the first release that used MCTS.

 

I don't have any on-line source older than version 10, and the older backups
are on floppies, so I can't read them any more J  I don't think I even have
backups any more for any code before 1990.

 

Everything from version 10 forward is in Git, so I could in theory see how
many lines are unchanged since 1997.

Has there been any studies into the number of lines of code in the top
chess/go programs over time?  Another measure would be bytes of executable
or bytes of executable+data.  Obviously the latter grows in chess with
endgame databases, so maybe that's less interesting.
