This update rule converges to the square root of S which turns out to be a special case of Newton method This could be the first application of Newton method
How do you know if Newton's method converges?
There are some conditions that must be met for Newton's method to converge:
1The function must be continuous and differentiable at the root. 2) The initial guess must be close enough to the root. 3) The derivative of the function must not be equal to zero at the root.
What is the convergence characteristics of the Newton-Raphson method of solving a load flow problem?
It possesses quadratic convergence characteristics. Therefore, the convergence is very fast. The number of iterations is independent of the size of the system. Solutions to a high accuracy is obtained nearly always in two to three iterations for both small and large systems.
Is the rate of convergence of the Newton-Raphson method generally linear?
Answer: Rate of convergence of the Newton-Raphson method is generally Linear. It states that the value of root through the Newton Raphson method converges slowly.
7Accuracy here is defined as the number of zeros to the right of the decimal place of xn+1 −xn. Generally Newton's method converges quadratically, however, when N (r) = 0 the method will converge only linearly as shown by Lemma 5.3. Lemma 5.3.
The order of convergence of Newton Raphson method is 2 or the convergence is quadratic. It converges if |f(x).f''(x)| < |f'(x)|2.
