Envy-free item assignment (EF assignment) is a fair item assignment problem, in which the fairness criterion is envy-freeness - each agent should receive a bundle that he believes to be at least as good as the bundle of any other agent. Since the items are indivisible, an EF assignment may not exist. The simplest case is when there is a single item and at least two agents: if the item is assigned to one agent, the other will envy. Therefore, the division procedures provide various kinds of relaxations.
