Both, unlike a line search that enforces the so-called Wolfe condition (see the book by Nocedal and Wright), do not guarantee that y k T s k >0 (here we use notation of Nocedal and Wright). So the equation I am trying to solve is : $$ f^{k+1}_{i,j}= f^k_{i,j}+\alpha^k G^k (i,j) $$ Below is a back tracking line search algorithm to find $\alpha_k$ but it is not being computed correctly I realize.

Find the treasures in MATLAB Central and discover how the community can help you! Pick an initial iterate x0 by educated guess, set k = 0. Matlab - Exact Line Search. Line Search Algorithm help. The following Matlab project contains the source code and Matlab examples used for newton method with line search. You are now following this Submission. Line Search Methods Shefali Kulkarni-Thaker Consider the following unconstrained optimization problem min f(x) x2R Any optimization algorithm starts by an initial point x 0 and performs series of iterations to reach the optimal point x.

Until xk has converged, i) Calculate a search direction pk from xk, ensuring that this direction is a descent direction, that is, [gk]Tpk < 0 if gk 6= 0 , so that for small enough steps away from xk in the direction pk the objective function will be reduced.

This is an implementation of an interior-point algorithm with a line-search method for nonlinear optimization. Vote. At each iteration, our algorithm works with a scalar function and uses an inner solver designed to nd a step-size satisfying the strong scalar-valued Wolfe conditions. % function [xk,k] = line_search(fun,R,x0,kup,epsilon,maxtol) % Calculation of function root with the quasi-Newton-Raphson method % accelerated by a line search algorithm % % Description % The equation fun(x)=R is solved for x, with R not equal to 0. 0. At any kth iteration the next point is given by the sum of old point and the
