Figure 4: Life cycle of a meso-agent (Duchene 2001).
Galanda (2003) introduced a strategy for evaluation of an agent plan. It
evaluates constraint violations based on agent situation. The minimum vio-
lation demonstrates that the state of an agent satisfies the constraint. The
violation is larger, the situation of agent is worse and it needs another plan
for generalization. Then, it calculates the sum of violations of all con-
straints. The smaller the sum, the better the plan. The agent records the
amount of violation for each plan and chooses the one with the minimum
violation. The advantage of this method is that it can quantify the effect of
each constraint so that the agent can find the balance between different
constraints.
