WebThe Miller–Rabin primality test or Rabin–Miller primality test is a probabilistic primality test: an algorithm which determines whether a given number is likely to be prime, similar to the … WebAlgorithm 2: Solovay-Strassen primality test The key idea here is that the two methods of computing a n must agree if n is prime. Clearly, if the algorithm outputs “composite”, n ∈ COMPOSITE. What remains is to show that, enough of the time, these two methods of computing the Jacobi symbol with disagree for composite n. Claim 10.
