C# 클래스 numl.Math.Probability.Sampling

SimpleRNG is a simple random number generator based on George Marsaglia's MWC (multiply with carry) generator. Although it is very simple, it passes Marsaglia's DIEHARD series of random number generator tests. Written by John D. Cook http://www.johndcook.com.

비공개 메소드들

메소드	설명
GetUint ( ) : uint	This is the heart of the generator. It uses George Marsaglia's MWC algorithm to produce an unsigned integer. See http://www.bobwheeler.com/statistics/Password/MarsagliaPost.txt.
Sampling ( ) : System	Static constructor.
SetSeed ( uint u ) : void	Sets a seed.
SetSeed ( uint u, uint v ) : void	The random generator seed can be set three ways: 1) specifying two non-zero unsigned integers 2) specifying one non-zero unsigned integer and taking a default value for the second 3) setting the seed from the system time.
