Definition: In the context of mathematics, a precongruential random number generator is an algorithm that produces pseudo-random numbers by repeatedly applying a fixed rule to generate a sequence. The term "precongruatulating" refers to this process as it was used in the development of the pseudorandom number generator (PRNG) called the Miller-Rabin primality test, which is widely used for generating random numbers with low probability of being prime. It's worth noting that while precongru
