We propose a line search algorithm for nding a step-size satisfying the strong vector-valued Wolfe conditions. This package contains several subdirectories corresponding to COIN-OR projects. Active 5 months ago. Start Hunting! 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). 0. At any kth iteration the next point is given by the sum of old point and the Ask Question Asked 5 months ago.

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. Line Search Algorithm help.

This is an implementation of an interior-point algorithm with a line-search method for nonlinear optimization. Matlab - Exact Line Search. The following Matlab project contains the source code and Matlab examples used for newton method with 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. The AUTHORS, LICENSE and README files in each of the … Generic Line Search Method: 1. 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.
