C# Class RandomOps.MersenneTwister

Pseudo-Random Number Generator (PRNG) using the Mersenne Twister algorithm by Makoto Matsumoto and Takuji Nishimura. This implementation is rewritten from their C source-code originally dated 2002/1/26. This PRNG has a very long period of 2^19937-1 (approximately 4.3 x 10^6001), and is hence known as MT19937. This implementation is the 32-bit version. Not thread-safe.

Public Methods

Method Description
MersenneTwister ( ) : System

Constructs the PRNG-object and seeds the PRNG with the current time of day. This is what you will mostly want to use.
MersenneTwister ( UInt32 seed ) : System

Constructs the PRNG-object using the designated seed. This is useful if you want to repeat experiments with the same sequence of pseudo-random numbers.
Rand ( ) : UInt32

Draw a random number in inclusive range {0, .., RandMax}

Protected Methods

Method Description
Seed ( UInt32 seed ) : void

Seed with an integer.
