a. Constraints of type (Q) : for each constraint E of this type, we add a slack variable A Ü, such that A Ü is nonnegative. Example: 3 5 2 T 6 2 translates into 3 5 2 T 6 A 5 2, A 5 0 b. Simplex Algorithm In General 1.Write LP with slack variables (slack vars = initial solution) 2.Choose a variable v in the objective with a positive coe cient to increase 3.Among the equations in which v has a negative coe cient q iv, choose the strictest one This is the one that minimizes p i=q iv because the equations are all of the form x i = p i + q ivx v. The simplex algorithm is the classical method to solve the optimization problem of linear programming. We first reformulate the problem into the standard form in which all constraints are expressed as equalities. Any constraint in inequality form The Simplex Algorithm whose invention is due to George Dantzig in 1947 and in 1975 earned him the National Medal of Science is the main method for solving linear programming problems.

A simplex is the geometrical figure in n dimensions consisting of n+1 vertices. In 2-D it is a triangle, in 3-D a tetrahedron.

The simplex method generates a sequence of feasible iterates by repeatedly moving from one vertex of the feasible set to an adjacent vertex with a A proposal which combines the normal and dual algorithms, with some modifications, in order to determine an optimal solution in fewer iterations than by other large-scale linear programming, simplex algorithm, pivot rule, nested, largest- distance, scaling.
