Abstract:Two modifications of the family of Chebyshev–Halley methods are given. The first is to improve the rate of convergence to a multiple zero of an analytic function. The second is to find simultaneously all distinct zeros of a polynomial.
Keywords:Chebyshev&ndash  Halley method  Multiple zero  Chebyshev&ndash  Halley-like method  Zero finding  Simultaneous  Analytic function  Decreasing ratio
