Newtonian Method软件

The algorithm summarizes Newton’s Method.

软件应用简介

Newton’s method uses information from the Hessian and the Gradient i.e. convexity and slope to compute optimum points. For most quadratic functions it returns the optimum value in just a single search or 2 iterations which is even faster than Conjugate Gradient method. This can be verified by comparing the results with Conjugate Gradient algorithm previously posted by me. However, in some cases for higher order or non-quadratic functions the method might diverge or it may converge to non-minimum stationary points. To guarantee convergence at minima often pre-conditioners are used. The pre-conditioners limit step size increasing the number of computations, but ensuring minimum solution.
