WebThe Miller-Rabin primality test is a probabilistic test used to determine whether or not a given integer is composite or a "probable prime". Deterministic variants exists (and depending on the size of the input can be quite fast and efficient while being simple to implement) but they are not robust enough to efficiently handle all situations.

"WebIf you run the algorithm 50 times with 50 random numbers, then the probability that your number (of less than 200 digits) is prime is greater than 99.99%. So you might ask: is there a completely deterministic test for primality? That was discovered recently by two undergraduates (and their advisor) in 2000. " - Deterministic primality test
