Package org.uncommons.maths.random

This package provides deterministic, repeatable, pseudo-random number generators, a set of strategies for seeding them, and classes for generating values from different probability distributions.

Description

Interface Summary

RepeatableRNG	Deterministic random number generators are repeatable, which can prove useful for testing and validation.
SeedGenerator	Strategy interface for seeding random number generators.

Class Summary

AESCounterRNG	Non-linear random number generator based on the AES block cipher in counter mode.
BinomialGenerator	Discrete random sequence that follows a binomial distribution.
CellularAutomatonRNG	Java port of the cellular automaton pseudorandom number generator developed by Tony Pasqualoni.
CMWC4096RNG	A Java version of George Marsaglia's Complementary Multiply With Carry (CMWC) RNG.
ContinuousUniformGenerator	Continuous, uniformly distributed random sequence.
DefaultSeedGenerator	Seed generator that maintains multiple strategies for seed generation and will delegate to the best one available for the current operating environment.
DevRandomSeedGenerator	RNG seed strategy that gets data from /dev/random on systems that provide it (e.g.
DiehardInputGenerator	Utility to generate an input file for the DIEHARD suite of statistical tests for random number generators.
DiscreteUniformGenerator	Discrete, uniformly distributed random sequence.
ExponentialGenerator	Continuous random sequence that follows an exponential distribution.
GaussianGenerator	Normally distributed random sequence.
JavaRNG	This is the default JDK RNG extended to implement the RepeatableRNG interface (for consistency with the other RNGs in this package).
MersenneTwisterRNG	Random number generator based on the Mersenne Twister algorithm developed by Makoto Matsumoto and Takuji Nishimura.
PoissonGenerator	Discrete random sequence that follows a Poisson distribution.
Probability	Immutable value type for probabilities.
RandomDotOrgSeedGenerator	Connects to the random.org website (via HTTPS) and downloads a set of random bits to use as seed data.
SecureRandomSeedGenerator	SeedGenerator implementation that uses Java's bundled SecureRandom RNG to generate random seed data.
XORShiftRNG	Very fast pseudo random number generator.

Exception Summary

SeedException

Exception thrown by SeedGenerator implementations when they are unable to generate a new seed for an RNG.
