Pick an initial iterate x0 by educated guess, set k = 0. Start Hunting! This package contains several subdirectories corresponding to COIN-OR projects. 2. Vote. 0 ⋮ Vote. Tags linesearch; See Also. 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. 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. 0. % 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. This is an implementation of an interior-point algorithm with a line-search method for nonlinear optimization. Active 5 months ago. Learn more about line search programming At any kth iteration the next point is given by the sum of old point and the 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. Generic Line Search Method: 1. Matlab programming (line search). 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.
