(b) At which iterations was the basic feasible solution degenerate? (c) Which of the pivots you performed were degenerate? (d) Sketch a three-dimensional picture of the feasible region. (e) Which, if any, of the four rst constraints is redundant? In other words, which, if any, of these constraints could you delete without changing the feasible region? 1...
