Page: The Newton Method
... Q:- Minimize $f(x_1,x_2)=2x_1-2x_2+2x_1^2+2x_1x_2+x_2^2 $ starting from the point $\begin{equation}X_1=\begin{bmatrix}0\\0\end{bmatrix}\end{equation}$ Solution:- $X_{1+i} = X_i-[J_i]^{-1}\nabla f_i$ and $\begin{equation} \nabla f=\begin{bmatrix} \frac{\partial f}{\partial x_1}\\ \frac{\part ...

Page: The Steepest Descent
... The Steepest Descent method, also called the Cauchy Method ,was put forward by Cauchy in 1857. In this method, we choose an initial point $X_1$ and iteratively move along the steepest descent direction to find the optimum point. Minimization occurs in the negative direction of the gradient vector . ...
