  2. Factorization of polynomials over finite fields - Wikipedia

    en.wikipedia.org/wiki/Factorization_of...

    Like distinct-degree factorization algorithm, Rabin's algorithm [5] is based on the Lemma stated above. Distinct-degree factorization algorithm tests every d not greater than half the degree of the input polynomial. Rabin's algorithm takes advantage that the factors are not needed for considering fewer d. Otherwise, it is similar to distinct ...

  3. Miller–Rabin primality test - Wikipedia

    en.wikipedia.org/wiki/Miller–Rabin_primality_test

    Miller–Rabin primality test. 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 ...

    en.wikipedia.org/wiki/Rabin_fingerprint

    Given an n-bit message m 0,...,m n-1, we view it as a polynomial of degree n-1 over the finite field GF(2). = + + … +We then pick a random irreducible polynomial ⁠ ⁠ of degree k over GF(2), and we define the fingerprint of the message m to be the remainder () after division of () by () over GF(2) which can be viewed as a polynomial of degree k − 1 or as a k-bit number.

  5. Five-point stencil - Wikipedia

    en.wikipedia.org/wiki/Five-point_stencil

    Five-point stencil. An illustration of the five-point stencil in one and two dimensions (top, and bottom, respectively). In numerical analysis, given a square grid in one or two dimensions, the five-point stencil of a point in the grid is a stencil made up of the point itself together with its four "neighbors".

  6. Irreducibility (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Irreducibility_(mathematics)

    Irreducibility (mathematics) In mathematics, the concept of irreducibility is used in several ways. A polynomial over a field may be an irreducible polynomial if it cannot be factored over that field. In abstract algebra, irreducible can be an abbreviation for irreducible element of an integral domain; for example an irreducible polynomial.

    Likewise, ⁠ θ / 5 ⁠ has a sine that is one of the five real roots of the equation 16 y 5 − 20 y 3 + 5 y − sin ⁡ ( θ ) = 0. {\displaystyle 16y^{5}-20y^{3}+5y-\sin(\theta )=0.} In either case, if the rational root test yields a rational root x 1 , then the quintic is reducible since it can be written as a factor ( x—x 1 ) times a ...

  8. Primality test - Wikipedia

    en.wikipedia.org/wiki/Primality_test

    The Solovay–Strassen test is an Euler probable prime test (see PSW [3] page 1003). For each individual value of a, the Solovay–Strassen test is weaker than the Miller–Rabin test. For example, if n = 1905 and a = 2, then the Miller-Rabin test shows that n is composite, but the Solovay–Strassen

  9. Fermat's little theorem - Wikipedia

    en.wikipedia.org/wiki/Fermat's_little_theorem

    The Miller–Rabin primality test uses the following extension of Fermat's little theorem: [14] If p is an odd prime and p − 1 = 2 s d with s > 0 and d odd > 0, then for every a coprime to p, either a d ≡ 1 (mod p) or there exists r such that 0 ≤ r < s and a 2 r d ≡ −1 (mod p).
