In all cases, assume the letter carriers must return to the post office.
1. List and informally define five desirable properties of the
negotiation protocol.
2. Consider the letter carrier domain. For the situation to the
right, in which currently agent 1 delivers to cities (A,B,D)
and agent 2 deliver to cities (A,B,C,D), show the
negotiation set (individually rational and pareto optimal
deals). Assume the distances are drawn to scale
Is there any lie that will increase an agent's utility?
Explain.
3. Consider the diagram to the right. Suppose Agent 1
delivers to {d, c} and A2 delivers to {b,e}. If g is a decoy
task of A2, show how A2 wins in all or nothing deals.
Specifically, show how much the utility of A2 is improved
by lying.
4. Consider the diagram to below over pure deals (each
person is assigned a specific set of tasks to try to equalize
the utility, but no probability is involved). A1 is assigned
to {b,a,d}. A2 is assigned to {b,a,d}. The distance to b is
