Z X1 x2 x3 s1 1 0 4 0 6 0 0 1/2 1 - 1/2 0 1 1/2 0 1/2 Suppose you obtain the above tableau when solving a minimization LP. What are the values of variables (x1, x2, x3)? N X1 x2 x3 s1 1 0 4 0 6 0 0 1/2 1 2 0 1 1/2 0 4 (Here, si is the slack variable and ei is the excess variable of constraint i.) What is B-1 for the current basis?

How much can the objective coefficient of X2 change without changing the optimal basis?
