For problems where you solve an LP using a version of the simplex method, you can use Vanderbei's pivot tool to help with the arithmetic. But in your solutions, record the pivots in the form the problem expects. So record your dual simplex pivots as tableaux (dictionaries are acceptable) and record your revised simplex pivots using the layout presented in the lecture slides. 2. Solve the following LP using the dual simplex method. At each iteration, choose the most negative primal variable to leave the basis. minimize 5x1 + 3x2 < -2 < 2 < -3 subject to -x1 X2 X1 + X2 -x1 X1, x2 > 0
