%description
|
|
As with other Pseudo-Random Number Generator (PRNG) algorithms like the
|
|
Mersenne Twister (see Math::Random::MT), this algorithm is designed to
|
|
take some seed information and produce seemingly random results as output.
|
|
However, ISAAC (Indirection, Shift, Accumulate, Add, and Count) has
|
|
different goals than these commonly used algorithms. In particular, it's
|
|
really fast - on average, it requires only 18.75 machine cycles to
|
|
generate a 32-bit value. This makes it suitable for applications where a
|
|
significant amount of random data needs to be produced quickly, such
|
|
solving using the Monte Carlo method or for games.
|
|
The results are uniformly distributed, unbiased, and unpredictable unless
|
|
you know the seed. The algorithm was published by Bob Jenkins in the late
|
|
90s and despite the best efforts of many security researchers, no feasible
|
|
attacks have been found to date.
