Hey everyone. I recently made my own cave generator based on Brian's
Cellular Automata at
http://www.herassmygod.org/bcr19374/programming/cellular/ and it works
beautifully.

What I don't understand is how it works. When I looked at the source
code, it says that "if at least X amount of tiles are within 1 radius
of a tile, and at most Y amount of tiles are within 2 radius of a tile,
then the tile changes".

I can't see the logic behind the "at most Y amount of tiles are within
2 radius" part. I don't really HAVE to, because it works fine with a
30% fill with a 4 0 2 generation and that's all I really need. But I'm
curious...

Can anyone explain this to me? Thanks!
