SUB

• Definition: This is a "meta"-generator which takes a subsequence out of another generator.
• Name (as given to prng_new): "sub(gen,s,i)".

  The output of "gen" is spliced into s streams, and the i-th is used. (0 <= i < s)

• Properties:
  • Period length: Typically the period of "gen".
  • Generally speaking, most properties of PRNG are preserved when taking subsequence.
  • prng_is_congruential and prng_can_seed depend on "gen".
  • prng_can_fast_sub and prng_can_fast_con are FALSE.
