Abstract:

The paper proposes an artificial fishswarm algorithm to determine the real roots of arbitrary polynomials.It uses the Krandom dividing method to optimize the real roots isolator interval for the sake of finding all real roots of arbitrary polynomials.Simulation experiments show that the proposed artificial fishswarm algorithm can fast isolate the real roots of arbitrary polynomials,and the Krandom dividing method can quickly optimize the real roots isolator interval to find all real roots of polynomial.The proposal features high precision and fast convergence.

Key words: polynomial;real roots isolator;Krandom dividing method;artificial fishswarm algorithm
