SOLVED:Exercise 7.17 Consider a network flow problem and assume that there exists at least one feasible solution. We wish to show that the optimal cost is ~O0 if and only if there exists a negative cost directed cycle such that every arc on the cycle has infinite capacity: (a) Provide proof based on the flow decomposition theorem. (b) For uncapacitated problems, provide proof based on the network simplex method_
