Function malachite_base::num::random::striped::striped_random_bool_vecs

pub fn striped_random_bool_vecs(
    seed: Seed, 
    mean_stripe_numerator: u64, 
    mean_stripe_denominator: u64, 
    mean_length_numerator: u64, 
    mean_length_denominator: u64
) -> StripedRandomBoolVecs<GeometricRandomNaturalValues<u64>>

Generates random striped Vec<bool>s.

See here for more information.

The lengths of the Vecs are sampled from a geometric distribution with a specified mean $m$, equal to mean_length_numerator / mean_length_denominator. $m$ must be greater than 0.

The mean run length (before the bit sequences are truncated) is $m$ = mean_stripe_numerator / mean_stripe_denominator.

Expected complexity per iteration

$T(n) = O(n)$

$M(n) = O(n)$

where $T$ is time, $M$ is additional memory, and $n$ is mean_length_numerator / mean_length_denominator.

Panics

Panics if mean_stripe_denominator is zero, if mean_stripe_numerator <= mean_stripe_denominator, if mean_length_numerator or mean_length_denominator are zero, or, if after being reduced to lowest terms, their sum is greater than or equal to $2^{64}$.
