An Artificial Fish-Swarm Algorithm to Determine the Real Roots of Polynomial

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.
