THE SIMPLEST, BUT NO SIMPLER, AGENT-BASED MODEL

In this paper, we describe what we believe to be the simplest agent-based model. More specifically we define the class of the simplest agent-based simulation model formulations, referred to as SABM. We describe the nine essential elements of agent-based simulation models in the class SABM and give an example of such a model. We find that the simplest ABM formulation provides a basis for a transparent, compact and elegant description of agent-based modeling. The design illustrates the essential characteristics of agent-based modelling as a field of research and application and facilitates the explanation of agent-based modeling. We hope that the simplest formulation demystifies agent-based modeling for those within the simulation community, as well as those new to the field such as researchers from other disciplines and application communities.
