Consider the minimum cost flow problem shown below, where the b values

Consider the minimum cost flow problem shown below, where the b values are given by the nodes, the Cij values are given by the arcs, and the finite u values are given in parentheses by the arcs. [125] 9 (UAD = 100) A 2 6 [0] 5 3 8 [-175] D E (a) Obtain an initial BF solution by solving the feasible spanning tree with basic arcs A C, B A, C D, and C E. All nonbasic arc has xij = 0 except XAD = 100. (b) Use the network simplex method to solve this problem. What is the total cost of the optimal solution? B [200] 00 8 (UBE = 100) [-150]
