Pseudorandom Number Generator: Seeds
built 812 days ago
The seed for the pseudorandom number generator used by RANDOM_NUMBER can be set or queried with RANDOM_SEED. If RANDOM_SEED is not used, the processor sets the seed for RANDOM_NUMBER to a processor-dependent value.

HENKOS pseudo-random number generator doesn't need especially resources; it can be actually to work in minimal system. There is ... the version for DOS/Windows as well the version for Linux. The generating speed of a sequence depends directly on of the system performances, as refer point the generator was tested on the system PII 300MHz, 32 MB RAM, DOS/Windows 98 / Linux (276.62 Mbps, for a seed of 640 bits).

The GNU Scientific Library provides a large collection of random number generators which can be accessed through a uniform interface. Environment variables allow you to select different generators and seeds at runtime, so that you can easily switch between generators without needing to recompile your program. Each instance of a generator keeps track of its own state, allowing the generators to be used in multi-threaded programs. Additional functions are available for transforming uniform random numbers into samples from continuous or discrete probability distributions such as the Gaussian, log-normal or Poisson distributions.

Sets the seed of this random number generator using a single long seed. The general contract of setSeed is that it alters the state of this random number generator object so as to be in exactly the same state as if it had just been created with the argument seed as a seed. The method setSeed is implemented by class Random by atomically updating the seed to

Edit 25 April 2007: It seems I’m not the only one to address Flash’s lack of a seed based random number generator. Michael Baczynski presents a more academic approach to random number generation in actionscript.

The benefit... in having this class is that each instantiation is independent, permitting several uncoupled random number generators to be present in the system at once. Moreover, each instantiation is automatically "pre-seeded", making calls to Random::srand unnecessary in most uses. Even arrays of Random items will operate independently.
