WebThe first deterministic primality test significantly faster than the naive methods was the cyclotomy test; its runtime can be proven to be O((log n) c log log log n), where n is the number to test for primality and c is a constant independent of n. Many further improvements were made, but none could be proven to have polynomial running time. WebThe benefits of the sieve technique include simple handling, low cost of operation, accurate and reproducible tests in comparatively short time and the probability of separating the fractions of particle size.
