behavior of the system in model 1 is similar to the activity of an inseсt, which moves in the
environment filled by a nutrient with variable concentration. Model 2 is, to some extent,
similar to the action of an eye of an animal.

Fig. 3. Architecture of model 2
The modules in this model are similar to those in model 1 but also include a vector of
differences (DV), its functioning is described below. In order to avoid the spurious activity
of modules filled by noise, a threshold of perception is used, i.e. module i is able to
participate in the activity of the system at iteration m only if

The interaction between module i and module j at iteration m occurs if the distance between
the modules, i.e. |(i-j)/z| is less than a certain parameter (p2) and the functional proximity

i and module j is as follows:
