GfsrGenerator Class

Represents a generalized feedback shift register pseudo-random number generator.

Namespace: Extreme.Statistics.Random
Assembly: Extreme.Numerics.Net20 (in Extreme.Numerics.Net20.dll) Version: 3.6.10055.0 (3.6.10077.0)

Syntax

C#
[SerializableAttribute] public sealed class GfsrGenerator : RandomWordGenerator

Visual Basic (Declaration)
<SerializableAttribute> _ Public NotInheritable Class GfsrGenerator _ Inherits RandomWordGenerator

Visual C++
[SerializableAttribute] public ref class GfsrGenerator sealed : public RandomWordGenerator

F#
[<SealedAttribute>] [<SerializableAttribute>] type GfsrGenerator = class inherit RandomWordGenerator end

Remarks

Use the GfsrGenerator class to represent a pseudo-this.random number generator that uses a fourth order generalized feedback shift register algorithm.

This generalized feedback shift register generator has a very long period of 2⁹⁶⁸⁹-1. Thanks to its simplicity, it is very fast. On the down side, the start-up time is significant.

GfsrGenerator can be used in place of the Random class to obtain pseudo-random numbers of a higher quality.
