Introduction to Primality Test and School Method

Near the beginning of the 20th century, it was shown that a corollary of Fermat's little theorem could be used to test for primality. This resulted in the Pocklington primality test. However, as this test requires a partial factorization of n − 1 the running time was still quite slow in the worst case. The first deterministic primality test significantly faster than the naive methods was the cyclotomy test; its runtime can be proven to be O((log n) ), where n is the number to test for primality and … WebLucas-Lehmer test for Mersenne numbers. Deterministic. A deterministic algorithm gives a de nitive result every time it is run. The opposite of deterministic is probabilistic, which gives an answer with some probability of being correct. For example, the Miller-Rabin test can correctly identify a number as composite over 75% of the time. Such WebI believe that the asymptotically fastest current (non-probabilistic) primality test is the "Lenstra/Pomerance improved AKS", which has complexity that is essentially O (n^6). … how many blaze rods are needed to get to end
