Share. … Web27 de ago. de 2024 · Newton's method has no global convergence guarantee for arbitrary functions, as you just learned. Now, people have posted examples of where Newton's method doesn't converge, but they're all rather "unusual" functions (some being very non-smooth), so it's natural to assume they're pathological and won't happen in practice.

If your f'(x) = 0.0001 (or anywhere close to zero, which has a chance of happening), your xn+1 gets thrown really far away from xn.. Worse yet, this can happen over and over due to f'(x) being a periodic function, … WebIf \(x_0\) is close to \(x_r\), then it can be proven that, in general, the Newton-Raphson method converges to \(x_r\) much faster than the bisection method. However since \(x_r\) is initially unknown, there is no way to know if the initial guess is close enough to the root to get this behavior unless some special information about the function is known a priori … golder-thompson gift
