the number of the agents-intruders, but the process of identification and elimination
proceeds slower than in the first case.
A comparison between the development of eliminating the agents-intruders in the
former and the latter case is presented in Fig.
5.20
.
In both systems there are cases of false identification of intruders. It results from
the fact that the normal agent is perceived as an intruder and eliminated from the
system. However, in neither of the cases the number of eliminated normal agents is
significant (a few percent).
In the examples of the operation of the system some delay may be observed at the
start of eliminating the intruders. The time is used by the normal agents for preparing
