be left in the system when it shut down at 7:00 p.m. (even

If you are using a ranking-and-selection procedure and two

competitors happen to fall within the indifference-zone, then ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
you don't really care too much which one you end up selecting. -
