Detailed Description

Linear congruential uniform pseudo-random number generator.

This generator is very fast requiring only a single integer multiply and add per iteration. However, the least significant bits of the numbers are less random; the most extreme case being the LSB which at best flips between 0 and 1. This generator also exhibits poor dimensional distribution, therefore it is best to have a different generator for each dimension, rather than sharing one.
