WebbCheck all combinations of point-to-point lines for minimum sum of errors; Simplex-based methods are the “preferred” way to solve the least absolute deviations problem. A Simplex method is a method for solving a problem in linear programming. The most popular algorithm is the Barrodale-Roberts modified Simplex algorithm. WebbTo use the simplex algorithm we need our LP in standard form maximise f = c ¯ T x ¯ subject to A x ¯ = b ¯ and x ¯ ≥ 0. The reason for introducing slack variables is solely to convert the constraints A x ¯ ≤ b ¯ to the standard form A x ¯ = b ¯ so that we can apply the simplex algorithm.
