(b) (i) Solve the MCNFP given in Figure 5 given the following initial basic feasible solution. Assume y_5 = 0. Note changes from the MCNFP given in Figure 4. Basic arcs = {(5, 1), (1, 2), (3, 4), (2, 3)}, where flow on these arcs is set to (4, 4, 3, 3), respectively. Nonbasic are at its lower bound = {(1, 3)}. All remaining arcs are nonbasic at their upper bounds. (ii) How much worse than optimal in terms of the objective function is the initial BFS? How about the initial BFS you created in part (b)? (iii) Consider the ease where two or more arcs hit their upper or lower bounds simultaneously during the process of determining the leaving basic arc in the created cycle during the steps of Network Simplex. Can we allow both arcs to leave the basis simultaneously? Explain
