included in a more general Ag 1 's plan aimed at achieving goal g through a complex action α .

Reduction of help

Here the delegee provides less help on τ than delegated .If

Adopts ( Ag 2 Ag 1 τ 1 ) ∧ Dom - c ( αα 1 ) (7.9)

with α 1 ,g 1 ) , the delegee reduces the task to a subpart of the requested one (see Fi-

gure 7.13). For example Ag 1 delegates Ag 2 to prepare a main course for a dinner and bring it
to her house. Ag 2 only buys the ingredients but does not cook them.
A sub-help is not necessary a help (although lower than expected). Maybe the realized
action and the achieved subgoal are completely useless (in a plan the coordination among the
actions and their results are also very important).
For example, in the case of the previous example, maybe the ingredients cannot be cooked
at Ag 1 's house because of a problem with the kitchen.

changing the delegator's plan (Figure 7.14). In fact, the delegee chooses a task that satisfies a
