Convergence properties of the SOR Weierstrass method for the simultaneous approximation of polynomial roots are considered. The choice of acceleration parameter is discussed.

✦ Synopsis
Many problems in mathematics and other natural sciences and techniques reduce themselves to determining all roots of generalized polynomial equations. We consider in this paper the situations in which the critical initial approximations {z:}, i = 1,. ,n, fail, when the iterative methods of Newton-Weierstrsss type are applied.

In this paper, we give the convergence analysis of the Euler-like iterative method for the simultaneous inclusion of all simple real or complex zeros of a polynomial. The established initial conditions provide the safe convergence of the considered method and the fourth order of convergence. These c
