COMPOUND

• Definition:

  This is a "meta"-generator which combines a number of PRNG into one single generator by adding the respective numbers modulo 1.

• Name (as given to prng_new): "c(generator1,generator2, ...)".

  Up to PRNG_MAX_COMPOUNDS generators are permitted. generatorX may be any valid generator definition, including a compound generator.

• Properties:
  • Period length: Least common multiple of the period length's of the component generators.
  • Generally speaking, most properties of PRNG are preserved if combining generators of the same type.
  • prng_is_congruential is FALSE.
  • prng_can_seed is TRUE.
  • The parameters of prng_seed is used to seed all seedable component generators.
  • prng_can_fast_sub and prng_can_fast_con depend on the underlying generators.
