15 | * Basic Linear Congruential Generator. This is one of the simplest and | ||
16 | * most common pseudo-random number generators out there. It's simple, | ||
17 | * fast, and does a decent job if you don't have any stastistical | ||
18 | * requirements other than "random looking." This is the algorithm included | ||
19 | * as the default random number generator in most standard libraries, | ||
20 | * although this one uses larger numbers internally, has a longer period, | ||
21 | * and more even distrubition of randomness accross it's bits than most | ||
22 | * implementations. | ||
