Definition

An agent-based model is a computational model of various processes such as social, economic, and physical. Agents are autonomous, follow specific rules of behavior, and interact. Agents in such models may have zero-intelligence, so that behave randomly, or be purposeful (or goal oriented) and learn. Learning agents are those who modify their behaviors in response to the past outcomes, and they are embedded in a model where agents make decision repeatedly.

Theoretical Background

The basic units of an Agent-Based Model are agents, which are entities characterized by autonomy and by adaption. The former means that there is no central or “top-down” control over their behaviors, and the latter represents the idea that they are reactive to the environment. It is a model of a decentralized system consisting of rather simple agents...
