You must read and use the information provided on NetLogo in this module’s Outline page before attempting this assignment.
1. Run NetLogo application. In File menu, use the Models Library option to find IABM Textbook -> chapter 3 -> Segregation Extensions. There is a simulation called Segregation Simple. Double click on this model to run it.
2. In the Segregation Simple model, use the Info tab to understand what this model is and how to use it. For this model, answer the following questions and save your answer in a Word file:
What happens when you run the model with the default settings? Run it a few times. What do you notice? (2 points)
Keep the population number the same, but change the %-similar-wanted value to run the model at various conditions. At what % -similar-wanted does the model not converge any more? In other words, the model vacillates, and does not stop (or takes a very long time to stop). (1 point)
Now that you find the %-similar-wanted at which the model does not converge, does it make a difference if you keep the %similar-wanted but change the population number? do the vacillating patterns persist? (2 points)
3. In the NetLogo -> File menu -> Models Library -> IABM Textbook -> chapter 3 -> Segregation Extensions, there are three Segregation Simple Extensions. For Extension 1 and Extension 2, use the Info tab to understand what this model is and how to use it. Then answer the following questions for each extension using the following format and save your answer in the same Word file used in Step 2 above:
Segregation Simple Extension #
What happens when you run the model with the default settings? Run it a few times. What do you notice? (2 points)
Keep the population number the same, but change the %-similar-wanted value to run the model at various conditions. At what % -similar-wanted does the model not converge any more? In other words, the model vacillates, and does not stop (or takes a very long time to stop). (1 point)
Now that you find the %-similar-wanted at which the model does not converge, does it make a difference if you keep the %similar-wanted but change the population number? do the vacillating patterns persist? (2 points)
At the end of step 3, explain how the individual preference for %-similar-wanted in Extension 2 affects the system’s ability to reach convergence. (5 points) hint: study the code in the Code tab, understand how individual turtle’s threshold of %-similar-wanted is calculated based on the general %-similar-wanted and how it affects the happiness of individual turtle.
4. In the NetLogo -> File menu -> Models Library -> IABM Textbook -> chapter 3 -> Segregation Extensions, there are three Segregation Simple Extensions. For Extension 3, use the Info tab to understand what this model is and how to use it. Then answer the following questions for each extension using the following format and save your answer in the same Word file used in Step 3 above:
Segregation Simple Extension #
What happens when you run the model with the default settings? Run it a few times. What do you notice? (2 points)
Keep the population number and the %-different-wanted the same, but change the %-similar-wanted value to run the model at various conditions. At what % -similar-wanted does the model not converge any more? In other words, the model vacillates, and does not stop (or takes a very long time to stop). (1 point)
Now that you find the %-similar-wanted at which the model does not converge, can you change the %-different-wanted to make the system converge again? If yes, what’s the %-different-wanted to use? (2 points)
At the end of step 4, explain how the two factors %-similar-wanted and %-different-wanted in Extension 3 affects the system’s ability to reach convergence. (5 points)
5. Build a NetLogo simulation as described in the Mystery PatternLinks to an external site. tutorial.
Complete Tasks 1-4 (15 points). Save the model as CC_Pattern.nlogo
Complete Task 5, question 1 (5 points), question 2 (5 points) by answering the questions and modifying the model your created in Tasks 1-4. Save the new model as myPattern.nlogo.
Write your answer to Task 5 question 3 in the same Word file used the above Step 4. List at least two other interesting combinations of values for n and r and explain why the patterns are interesting to you (5 points).
Submit the Word file containing the answers from Steps 2-5 in this project, and the NetLogo models (the file CC_Pattern.nlogo and myPattern.nlogo) you create.
