Detailed Description

A simple random generator using MWC, CONG, and SHR3 by George Marsaglia (1999; internet posting).

Here is an excerpt from the posting describing this generator: The KISS generator, (Keep It Simple Stupid), is designed to combine the two multiply-with-carry generators in MWC with the 3-shift register SHR3 and the congruential generator CONG, using addition and exclusive-or. Period about 2¹²³. It is one of my favorite generators.
