Damm Algorithm
The original dissertation is in German: http://archiv.ub.uni-marburg.de/diss/z2004/0516/pdf/dhmd.pdf
Translations, anyone?
Wikibooks has code examples: http://en.wikibooks.org/wiki/Algorithm_Implementation/Checks...
Interesting. The Wikipedia article says:
> Despite its desirable properties in typical contexts where similar algorithms are used, the Damm algorithm is largely unknown and scarcely used in practice.
To what degree is this true?
This is a placeholder for the inevitable punning that will (and should?) ensue.
