Minimum Cost Network Flows


Below is a java applet that will present a set of min-cost network-flow problems for you to solve. You're job is to solve each problem (either by finding an optimal solution or demonstrating that the problem is infeasible or unbounded). After correctly solving a problem, the applet will immediately give you a new one. After you have solved all the problems in the set, press the Submit button to email your score to your instructor (whose email address must be supplied below).
