HW #5 Solution Adding slack variables we get the following initial tableau: The basis is . We only have one choice for entering variable which is . The ratios are . Thus either or can leave the basis, but we choose to leave by the smallest subscript rule. This tableau corresponds to the basic feasible solution . This BFS is DEGENERATE since a basic variable is zero. Iteration 1 The basis is . We only have one choice for entering variable which is . The ratios are . Thus will leave the basis. This tableau corresponds to the basic feasible solution . This BFS is DEGENERATE since a basic variable is zero. The pivot performed in this iteration is DEGENERATE since the BFS remains unchanged. Iteration 2 The basis is . We only have one choice for entering variable which is . The ratios are . Thus either or can leave the basis, but we choose to leave by the smallest subscript rule. This tableau corresponds to the basic feasible solution . This BFS is DEGENERATE since a basic variable is zero. The pivot performed in this iteration is
