May 21,  · My MATLAB code is based on the recent work in interior-point methods, specifically those methods that keep track of both the primal and dual optimization variables (hence primal-dual methods). These methods are special because they are numerically stable under a wide range of conditions, so they should work well for many different types of. Interior-Point-Legacy Linear Programming Introduction. The default interior-point-legacy method is based on LIPSOL (), which is a variant of Mehrotra's predictor-corrector algorithm (), a primal-dual interior-point method. Main Algorithm. The algorithm begins by applying a series of preprocessing steps (see Preprocessing). After preprocessing. •a primal-dual interior point method. The simplex and active-set algorithms are usually used to solve medium-scale linear programming problems. If any one of these algorithms fail to solve a linear programming problem, then the problem at hand is a large scale problem. Moreover, a linear programming problem with several thousands ofCited by: primal-dual interior- point methods for linear Learn more about linear problem, linear programming, interior-point methods, starting point, algorithm.
