Golomb rulers have been featured twice in the Computer Recreations
column of Scientific American, which did much to popularize them.
The most recent feature, and a nice introduction to the problems
and their applications, is the following.
A. K. Dewdney, "Computer Recreations,"
Scientific American, December 1985, pages 16-26,
and a follow up on March 1986, page 21.
