An accelerated version of Newton’s method with convergence order 3+1

A root-finding method is developed that, like Newton’s Method, evaluates both the function and its first derivative once per iteration, but the new method converges at the rate 3+1, and moreover, it’s asymptotic error constant is proportional to the function’s fourth order derivative. By contrast, N...
