- Abstract:
-
Brownian agents denote a particular class of agents that combines
features of reactive and reflexive agent concepts. A Brownian agent is
characterized by a set of state variables that include also internal
degrees of freedom. The dynamics of these state variables is in general
described by a stochastic equation that further considers direct and
indirect interactions with other agents and external influences. An
important state variable, the internal energy depot, captures the costs
of each action of the agent. In the paper, we discuss two biological
applications of the Brownian agent concept: (i) the formation of swarms
which depends on the active motion of the agents and some appropriate
coupling, (ii) the formation of aggregates based on chemotactic
interaction of the agents. We also demonstrate one of the major
advances of the Brownian agent concept, namely the derivation of
macroscopic equation from the agent dynamics, which can be used to
analyze and predict the behavior of the MAS.
