Communicative actions are used to deal with other
agents. There are four classes:
(INFORM
(REQUEST
(UNREQUEST
(REFRAIN
t a fact)
t a action)
t a action)
a action)
(t specifies the time the message is to take place, a is the
agent that receives the message, and action is any action
statement. An INFORM action sends the fact to agent a, a
REQUEST notifies agent a that the requester would like
the action to be realised. An UNREQUEST is the inverse of
a REQUEST. A REFRAIN message asks that an action not
be committed to by the receiving agent.
