#NIST SP 800-90A is a publication with the title Recommendation for #RandomNumber Generation Using Deterministic Random Bit Generators.
The publication contains the specification for three allegedly cryptographically secure #pseudorandom number generators for use in #cryptography : #HashDRBG (based on hash functions), HMAC DRBG (based on HMAC), and CTR DRBG.

Challenge: Given a 33 bit shift register based random number generator, shifting 32 times to make a random integer, we observe that a given value will always appear twice in the sequence. Generally unevenly spaced. How to find a value which has the closest repeat?
We could run for 2^33 iterations and keep a record in a many gigabyte array, but I imagine there's a better way.
Boosts OK!

In March 2021 I was obsessed with Langton's Ant experiments, but eventually after generating thousands of images of various walks I got bored.
This morning, I came up with an idea: how about adding primality check to the algorithm? For example if the current step number is a prime number, reverse walk direction.
Result?
More irregular, more interesting walk paths!
