In computer science, the term “agent” usually denotes a software abstraction of a real entity which is capable of acting with a certain degree of autonomy. For example, in artificial societies, agents are software abstractions of real people, interacting in an artifical, simulated environment. Various authors have proposed different definitions of agents. Most of them would agree on the following set of agent properties:

  • Persistence: Code is not executed on demand but runs continuously and decides autonomously when it should perform some activity.

  • Social ability: Agents are able to interact with other agents.

  • Reactivity: Agents perceive the environment and are able to react.

  • Proactivity: Agents exhibit goal-directed behavior and can take the initiative.
