Detailed Description

Class RWRandGenMCG59 generates random numbers uniformly distributed over the interval [0, 1], and may be used instead of class RWRandGenerator as a template parameter to any of the distribution generators derived from abstract base class RWTRand<> . RWRandGenMCG59 is a 59-bit multiplicative congruential generator.

Unlike class RWRandGenerator, each instance of RWRandGenMCG59 contains and maintains its own, independent state. This can make it easier to use in some situations. The "internal state" of an instance of RWRandGenMCG59 consists of only a seed.

Constructor & Destructor Documentation

RWRandGenMCG59::RWRandGenMCG59

(

)

[inline]

Constructs a generator, abitrarily seeded by a call to the time() function.

RWRandGenMCG59::RWRandGenMCG59

(

unsigned long

seed

)

[inline]

Constructs a generator with a specified seed.

RWRandGenMCG59::RWRandGenMCG59

(

const RWRandGenMCG59 &

u

)

[inline]

Constructs a copy of u. The copy's state will equal the state of u at the time the copy is created, but will not share the state of u.
