In this method, we: 1.Solve an auxiliary problem, which has a built-in starting point, to determine if the original linear program is feasible. If we succeed, we nd a basic feasible solution to the orignal LP. 2.From that basic feasible solution, solve the linear program the way we’ve done it before. fit financial keswick

"WebbIt enabled solutions of linear programming problems that were beyond the capabilities of the simplex method. In contrast to the simplex method, it reaches a best solution by traversing the interior of the feasible region. The method can be generalized to convex programming based on a self-concordant barrier function used to encode the convex set. " - Simplex method ppt

All the constraints (except those with equality (=) sign) are modified to ‘less-than-equal-to’ sign. Constraints with greater-than-equal-to’ sign are multiplied by -1 through out so that inequality sign gets reversed.
