its contribution if the agent chooses to violate the norm (
Algorithm
4 line 16). There-
fore,
Algorithm
3 should be used to evaluate the contribution of the fulfilment of the
norm to the agents' desires/intentions and
Algorithm
4 should be used to calculate the
contribution of the violation of the norm to the agents' desires/intentions.
If the contribution for fulfilling the norm is greater than or equal to the contribution
for violating the norm, the norm is selected to be fulfilled and added to the sub-set
Fulfill
of the activated norms. Such step is represented in
Algorithm
5 from line 4 to 6.
Otherwise, it is selected to be violated and added to the sub-set
Violate
of the activated
norms. Such step is represented in
Algorithm
5 from line 6 to 8.
In order to exemplify the applicability of the EN task, let's consider the rescue oper-
ation scenario. The evaluation of the benefits of fulfilling and violating the three norms
