You are running a physics experiment with n complicated steps that you must do in order, and students sign-up for some steps to help. Your experiment requires n steps, and each of the m students gives you a list of which steps they can help out with (steps require special skills). From experience, you know things run most smoothly when you have as little switching of shifts as possible. For example, if your experiment has <1, 2, 3, 4, 5,...
