The shape preservation constraint maintains the shape of the objects in
order to preserve the terrain morphology. For line agent, this constraint
preserves its shape and tends to reduce displacements. For feature agent,
this constraint evaluates the elevation and distance between the isobaths in
order to preserve the shape of the feature.

Table 4:
Shape preservation constraint
Structural constraints preserve topological relationships between lines and
features and the data structure consistency by imposing constraints on
actions. The detail of this constraint is shown as

4.2.4. Evaluation method of agent actions
One important characteristic of MAS is that the agent can propose several
plans and choose the best one automatically in this system. This means the
agent has a method to evaluate its situation. This part will introduce the
evaluation method of agent.
In our project, there are four types of constraints and some can be contra-
dictory. The shape constraint opposes the legibility constraint as one tends
