Ran |
Ran800: huge period generator TT800 of Matsumoto and Kurita.
Returns integer random numbers uniformly distributed within [0,4294967295]
(that means [0,2^32-1].

public class Ran800 : RandomGenerator
The Ran800 type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | Ran800 | Initializes a new instance of the Ran800 class. |
| Ran800(UInt32) | Initializes a new instance of the Ran800 class with a specified seed. |
Properties| Name | Description | |
|---|---|---|
 | Maximum | The maximum value of the random number which can be returned. (Inherited from RandomGenerator) |
| Seed | Gets the current seed value. (Inherited from RandomGenerator) |
Methods| Name | Description | |
|---|---|---|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| Long | The generation function. (Overrides RandomGeneratorLong) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
Fields| Name | Description | |
|---|---|---|
 | max_val | Uniform long int values within [0...max_val]. (Inherited from RandomGenerator) |
| seed | The seed of the random generator. (Inherited from RandomGenerator) |
Remarks
This is a twisted GFSR generator proposed by Matsumoto and
Kurita in the ACM Transactions on Modelling and Computer
Simulation, Vol. 4, No. 3, 1994, pp. 254-266. This generator has a
period of 2^800 - 1 and excellent equidistribution properties up to
dimension 25. A TGFSR with a period of more than 2^11000 is
currently under construction by M. Matsumoto and T. Nishimura.
The original code has been adapted to the general random generator class
interface of Matpack, 1997.
Original notes of the authors:
A C-program for TT800 : July 8th 1996 Version
by M. Matsumoto, email: matangus@math.keio.ac.jp
genrand() generate one pseudorandom number with double precision
which is uniformly distributed on [0,1]-interval
for each call. One may choose any initial 25 seeds
except all zeros.
