11.2.1 Newton’s method for single-variable optimization Instead of using Newton’s method to find \ ( f (x)=0 \), we can use it to find \ ( f' (x) = 0 \) and thus find extrema more directly. Check for yourself that now the iteration is \ [ x_ {t+1} = x_t - \frac {f' (x_t)} {f'' (x_t)}. \]

notes on newton’s method for optimization The roots of rf correspond to the critical points of f But in optimization, we will be looking for a specific type of critical point (e.g. minima and maxima) rf = 0 is only a necessary condition for optimization. We must check the second derivative to confirm the type of critical point.

• One can view Newton’s method as trying successively to solve ∇f(x)=0 by successive linear approximations. • Note from the statement of the convergence theorem that the iterates of Newton’s method are equally attracted to local minima and local maxima. Indeed, the method is just trying to solve ∇f(x)=0.

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 known as the critical points of f.

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 known as the critical pointsof f. These solutions may be minima, maxima, or saddle point…
