WebThe AKS primality test (named after Manindra Agrawal, Neeraj Kayal and Nitin Saxena) was the first deterministic primality test ever that works in polynomial time, i.e. it can test whether a given ... WebHowever, a number of effective algorithms exist that test the primality of a number by using a sequence of randomly chosen integers as input to relatively simple computations. If the sequence is sufficiently long (but far, far less than 10 150), the primality of a number can be determined with near certainty.
