WebApr 27, 2024 · Closed 3 years ago. To check if n is prime, one only need to try dividing n by numbers up to n, meaning that the complexity would be O ( n). In my opinion, O ( n) < O ( n) so this simple algorithm is already P. But why did people think that primality test is NP, and were surprised by the AKS primality test? WebA primality test is an algorithm for determining whether an input number is prime. Among other fields of mathematics, it is used for cryptography. Unlike integer factorization, primality tests do not generally give prime factors, only stating whether the input number is …
