Newton method maximization
In calculus, Newton's method is an iterative method for finding the roots of a differentiable function F, which are solutions to the equation F (x) = 0. As such, Newton's method can be applied to the derivative f ′ of a twice-differentiable function f to find the roots of the derivative (solutions to f ′(x) = 0), also … Zobacz więcej The central problem of optimization is minimization of functions. Let us first consider the case of univariate functions, i.e., functions of a single real variable. We will later consider the more general and more … Zobacz więcej The geometric interpretation of Newton's method is that at each iteration, it amounts to the fitting of a parabola to the graph of $${\displaystyle f(x)}$$ at the trial value $${\displaystyle x_{k}}$$, having the same slope and curvature as the graph at that point, and then … Zobacz więcej Newton's method, in its original version, has several caveats: 1. It does not work if the Hessian is not invertible.
