In the matrix simplex tableau, suppose that X = (X I , X II ) T ,
Question:
In the matrix simplex tableau, suppose that X = (XI, XII)T, where XII corresponds to a typical starting basic solution (consisting of slack and/or artificial variables) with B = I, and let C = (CI, CII) and A = (D, I) be the corresponding partitions of C and A, respectively. Show that the matrix simplex tableau reduces to the same form used in Chapter 3—namely,
