Table 3. Parameters Modifiable in the BVL

Both controls have a display to inform of the states of the simulation, environment, or
animat. The animat controls can display the actual state of the blackboard levels, of the
coupling strengths involved in the learning processes, of the

internal behaviour, and of the - ’s that regulate the imitation of behaviours.

5.5. About the BVL

All the presented properties of the BVL allow a wide variety of possibilities in order to
produce interesting experiments and simulations.

As with real animals, the animats in the BVL often present non obvious behaviours. But,
in difference with real animals, we can easily observe and change the internal states and
mechanisms of the animats, providing understanding of their behaviours, and also about
adaptive behaviour in animals. This is, not only it provides artificial adaptive behaviour, basing
ourselves in ethology, but it gives ethology back a greater understanding of adaptive behaviour
and its internal processes.

Our BVL at the present stage may be limited. But indeed it seems that you can never
stop counting the small details of animal behaviour you can simulate. For our present purposes,
all the properties of the BVL, enhanced by the ones of BeCA and the I&I model, seem to be
a good start.
