A parabola method formula with super-quadratic convergence. (Chinese. English summary) Zbl 1212.65200

Summary: The study introduces multipoint iteration into the memory single-point Muller’s method, and establishes a memory multipoint iterative parabola method with super-quadratic convergence. The order of convergence of this new method is 2.414, which is higher than that of Muller’s method. Numerical examples show that the new method is more efficient than Muller’s method and Newton’s method.
