Probabilistic tests are more rigorous than heuristics in that they provide provable bounds on the probability of being fooled by a composite number. Many popular primality tests are probabilistic tests. These tests use, apart from the tested number n, some other numbers a which are chosen at random from some sample space; the usual randomized primality tests never report a prime number as composite, but it is possible for a composite number to be reported as prime. The pr… maranatha veglia pasqualeWebIn general, primality tests can only tell you that a number n either ‘is composite’, or ‘can’t tell’. They cannot conﬁrm that n is prime.
