ACKNOWLEDGMENT

This model is from Chapter Eight of the book "Introduction to Agent-Based Modeling: Modeling Natural, Social and Engineered Complex Systems with NetLogo", by Uri Wilensky & William Rand.

This model is in the IABM Textbook folder of the NetLogo Models Library. The model, as well as any updates to the model, can also be found on the textbook website: http://www.intro-to-abm.com/.

WHAT IS IT?

This model illustrates how to use the RUN-RESULT command in NetLogo, which enables the runtime execution of different commands that are encoded as text and reports a result.

As opposed to the RUN command which executes procedures the RUN-RESULT command works as a runtime reporter.

HOW IT WORKS

The model initially creates 20 agents and a list of inputs, such as HEADING and XCOR, and operators, such as +, -, etc. It then sets the strategy for each of the agents to a random set of five of input / operators combinations. When the model runs the agents simply executes their strategy.

HOW TO USE IT

Press SETUP to create the agents and strategies.

Press GO to run the agent strategies for some time.

THINGS TO NOTICE

Do all the agents do the same thing? Can you tell the difference between the different strategies?

EXTENDING THE MODEL

Change the list of inputs and operators and see how that affects the results of the model.

RELATED MODELS

The Simple Machine Learning model builds on the present one to demonstrate how you can optimize the agents' strategies by letting them evolve over time.
