• Page 135, problem 13: At the bottom of the page, in the final tableau, in the list of basic variables, the x_2 and x_3 and interchanged.
• Page 137, problem 15: Under x_5 in the second table, the 15 should be 3/2.
• Both problems 8 and 9 on pgs 197-199 appear to have problems.
  Prob 8: I am not sure how to prove statement b rigorously. (I would appreciate an answer if someone else has one.) In addition, the line:
  "Assume that the initial ......so that y_0^* > 0 " is not quite right - the statement should just read:
  "Assume that y_0^* > 0." (since strict complementarity does not have to hold)
  Prob 9: The hint DOES work with the assumption that the optimal value Vn > = 0 in problem 8.
• Page 358, #17: the shadow prices given in the text are wrong.
• Page 361 #22: The value of the solution (66.8) does not agreed to the objective value of the given solution. It should have been 74.8.
• Page 361 #23: the current solution is NOT optimal. Therefore, part c) where they ask you to show that this solution is optimal seems to be wrong.
• Page 411, # 12: This problem is trivial under the current assumptions of integrality. It should be changed to $x_4,x_5$ integral.
