Run Example

If you download the NetLogo application, this model is included. You can also Try running it in NetLogo Web

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 command in NetLogo, which enables the runtime execution of different commands that are encoded as text. This is often useful if you want to construct turtle commands on the fly.

HOW IT WORKS

The model initially creates 100 agents and a list of commands, such as bk 1, lt 90, etc. It then sets the strategy for each of the agents to a random set of five of those commands. 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 commands and see how that affects the results of the model.

RELATED MODELS

Sandpile Simple demonstrates the use of the run primitive with tasks instead of strings.
