WebbNow we can use the dual simplex method to solve this tableau, getting: x y s 1 s 2 s 3 y 0 1 3=2 0 1=2 1 x 1 0 2 0 1 1 s 2 0 0 1=2 1 3=2 1 1z 0 0 =2 0 1=2 5 In this example, we got the integer solution (x;y) = (1;1), so we are done. This is not always guaranteed to happen; it’s possible that more fractional cuts will be necessary. 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.
