5.3.6. I&I in the animats

The imitation and induction (I&I) model presented in Section 4.1 is used by the animats
to communicate and socialize by imitating and inducing their behaviours.

For example, if animat Paco is hungry, and he is perceiving no food sources, but he is
perceiving animat Pepe executing the behaviour “approach food”, he will imitate him by
approaching to Pepe. Once he perceives the food source Pepe was approaching to, he will
approach to it. Induction occurs in a similar way.

5.4. The Interface

The interface of the BVL allows to perform a wide variety of simulations and
experiments. It consists of one window containing the general controls of the BVL and one
window for each animat created in the BVL, as the ones shown in Figure 24 and Figure 25.

The general controls window allow the user to save, load, and reset animats,
environments, and simulations. Animats are saved with all their properties (internal states,
learning states, parameters, and attributes). Simulations handle animats and environments as
one. This allows to save initial, partial, or final states of experiments easily. In this window, the
user can add and remove external stimuli, randomly or with specific positions and magnitudes;
pause and resume the simulation; adjust the refresh rate of the graphics (time steps / step
painted); and set a delay for each simulation interval in milliseconds.
