Multi-Agent Modeling: Black Hole Bounce and Grass Growth Variations in NetLogo

This course by Prof. Harry Howard at Tulane University focuses on multi-agent modeling using NetLogo. Students create simulations where black holes interact with moving objects on a 2D grid. The project requires coding a yellow box representing a black hole, which alters the heading of balls when they enter. Additionally, students explore how variations in rules affect turtle movements and grass growth through parameters and code adjustments. These projects help develop skills in coding and understanding complex systems.

  1. Q4 Day 19 COLQ 201 Multiagent modeling Harry Howard Tulane University

  2. Course organization • http://www.tulane.edu/~howard/Multiagent/ COLQ 201, Prof. Howard, Tulane University

  3. Black hole bounce

  4. Create the black hole to draw-black-hole ask patches with [abs pxcor < 5 and abs pycor < 5] [set pcolor yellow] ;; i created a yellow box in the center of the billiard table (black hole) end COLQ 201, Prof. Howard, Tulane University

  5. Bounce to bounce if abs [pxcor] of patch-ahead 0.1 < 5 and abs [pycor] of patch-ahead 0.1 < 5 [ set heading (random(145)) ] ;; the procedure was changed, and if a ball enters the box in the center (black hole), the balls heading changes to a new number between 1 and 145 end COLQ 201, Prof. Howard, Tulane University

  6. Variations • Go through everyone's. COLQ 201, Prof. Howard, Tulane University

  7. Q5 • In Tutorial #3: Procedures, right before "What's next?" at the end there are the following questions: • Finally, what other slider could you add to vary how often grass grows back? • Are there rules you can add to the movement of the turtles or to the newly hatched turtles that happen only at certain times? • Q5: Add code to answer both questions. Document your additions by comments alongside the code, AS WELL AS in the Information tab. (so you have to figure out how it works.) • The best way to do this is to follow the instructions step by step, so you understand everything! • Name your program: Q5-YourLastName-Tut3. • Drop it into the dropbox by class on Wednesday, March 3. COLQ 201, Prof. Howard, Tulane University

  8. Next time • Q5 due by class on Wed. • Evolutionary biology: social factors COLQ 201, Prof. Howard, Tulane University
