WebMay 11, 2016 · Testing a full primality test is a bit harder. It gets very hard when the test is unreasonably slow, such as many AKS implementations that have little testing done if they take minutes or hours to run every tiny inputs. Test the individual components separately. That includes M-R, Lucas, pre-tests, etc. Make sure those parts all work. WebThere are more general primality tests for N + 1 based on (partial) knowledge of the factorisation of N, but they tend to be less elegant. For example, this was snipped from "Factorizations of bn ± 1, b = 2, 3, 5, 6, 7, 10, 11, 12 Up to High Powers" by Brillhart, Lehmer, Selfridge, Tuckerman, and Wagstaff, Jr.: Theorem 11.
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…
