WebThe Miller–Rabin and the Solovay–Strassen primality tests are simple and are much faster than other general primality tests. One method of improving efficiency further in some cases is the Frobenius pseudoprimality test ; a round of this test takes about three times as long as a round of Miller–Rabin, but achieves a probability bound comparable to seven rounds of … WebThe key mathematical object in the test is called a "witness". Roughly speaking, a "witness" is just another integer that satisfies some modular arithmetic conditions that depend on the …
Web$\begingroup$ But 294409 doesn't pass the Miller-Rabin test with base 2. The question has a bit of ambiguity about Fermat vs. Miller-Rabin -- you're answering for his first portion (Fermat) vs. his second ("give false positives to the Rabin-Miller test") which is more difficult (but possible as my comment to the question indicates). $\endgroup$ The 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 Fermat primality test and the Solovay–Strassen primality test. It is of historical significance in the search for a polynomial-time … See more Similarly to the Fermat and Solovay–Strassen tests, the Miller–Rabin primality test checks whether a specific property, which is known to hold for prime values, holds for the number under testing.

We write n − 1 as 2 × 55, so that we have s = 2 and d = 55. We randomly select a number a such … See more The algorithm can be written in pseudocode as follows. The parameter k determines the accuracy of the test. The greater the number of rounds, the more accurate the result. See more By inserting greatest common divisor calculations into the above algorithm, we can sometimes obtain a factor of n instead of merely determining that n is composite. This occurs for example when n is a probable prime to base a but not a strong probable … See more

Probabilistic tests are more rigorous than heuristics in that they provide provable bounds on the probability of being fooled by a composite number. Many popular primality tests are probabilistic tests. These tests use, apart from the tested number n, some other numbers a which are chosen at random from some sample space; the usual randomized primality tests never report a prime number as composite, but it is possible for a composite number to be reported as prime.
