Return to the standard-form LP of Exercise 6-34(a).

(a) Solve the model by Primal-Dual Simplex Algorithm 6B starting from dual solution v = 10, 02. At each major step, state the restricted primal, the dual solution v, reduced costs on all primal variables, and the direction of change v. Also verify that each v is complementary with the latest x, and that each v is improving in the dual.

(b) Track your progress with Algorithm 6B on an (x1, x2) plot of the original LP, and comment.
