Agent Based Models
Transcript of Agent Based Models
agent based models?
They are a method
of simulating a system of
individuals and how they
interact with eachother
and their environment.
What is an agent?
Any individual or
"entity" in the simulation that
performs an action Key Elements and Properties - Individual agents
Agents have internal properties
-these influence behavior
Rules of behavior and interaction
-includes boundaries, obstacles, etc History John Von Neumann -
Conceptually conceived ABMs in the late 1940
Started with a self replicating machine idea
The Von Neumann Machine Cellular Automata Stanislaw Ulam John Conway's
Game of Life Rise of Computers Robert Axelrod's
Competitive demo of Game Theory Craig Reynold's
Biological representation and research ABMs as a means to study social phenomena and economics Christopher

for simulating scenarios that
feature many interactions or
random chance. Examples include
