However, it is our opinion that the results of Lustig, Marsten and Shanno (hereafter LMS) somewhat overstate the performance of these methods relative to the simplex method. We will present a sightly different view of progress in linear programming, one in which barrier methods do not dominate in the solution of large-scale problems.20 ppengTechnical reportTR93-40
