Class 28. Theoretical class 17. Analysis of the complete partner discovery scenario with planning agents

Show that even though the partner discovery agent receives information about three (N) communities of  book publisher representative agents, it is possible that it considers only one (M, 1 =< M < N) of those representative agents.

Show that get_community_members (the action following XXX) must wait until it receives answers from all the questioned secretary general agents or until a specified waiting time elapses (whatever happens first)

This motivates the existence of post-execution waiting conditions.
