Introduction to NetLogo
NetLogo is a powerful agent-based modeling environment widely used in education and research. It allows users to create and analyze complex systems through simple code and visual models. As you advance in your studies, the challenges you face in NetLogo programming can become more sophisticated, requiring a deep understanding of the platform's capabilities.
In this blog, we will tackle two master-level NetLogo programming questions. These examples will demonstrate the level of detail and expertise our team brings to each assignment.
Question 1: Predator-Prey Model with Environmental Factors
Problem Statement
Develop a predator-prey model in NetLogo that includes environmental factors such as food availability and habitat quality. The model should simulate the interactions between predators (e.g., wolves) and prey (e.g., rabbits) over time. Additionally, incorporate seasonal changes that affect food availability and habitat quality.

[ifelse season = "Summer" [set pcolor scale-color yellow food-level 0 1]

]
end
; Predators hunt prey to gain energy
to hunt-prey

if target != nobody [
ask target [die]

]
end
; Turtles reproduce if they have enough energy

set energy energy / 2

end
; Turtles die if they run out of energy
to death
if energy <= 0 [die]
end
; Turtles move randomly

set energy energy - 0.1
end
Explanation
This model simulates the interactions between predators and prey, considering environmental factors like food availability and habitat quality. The model includes seasonal changes, affecting food levels and habitat quality. Predators hunt prey to gain energy, while prey consumes grass. Both predators and prey reproduce if they have enough energy, and they die if their energy levels fall to zero.
Question 2: Disease Spread in a Population
Problem Statement
Create a NetLogo model to simulate the spread of a contagious disease within a population. The model should include different infection rates, recovery rates, and the possibility of reinfection. Additionally, incorporate measures like vaccination and quarantine to study their effects on disease spread.
Solution
; Define turtles' properties
turtles-own [infected? immune? days-infected]
; Setup procedure
to setup
clear-all
setup-patches
setup-turtles
reset-ticks
end
; Setup patches
to setup-patches
ask patches [
set pcolor white
]
end
; Setup turtles with some initial infections
to setup-turtles
create-turtles 200 [
setxy random-xcor random-ycor
set infected? false
set immune? false
set days-infected 0
if random-float 1 < 0.1 [set infected? true set color red]
else [set color blue]
]
end
; Main simulation procedure
to go
if not any? turtles with [infected?] [stop]
ask turtles [
move
spread-disease

]
tick
end
; Turtles move randomly
to move
rt random 360
fd 1
end
; Turtles spread disease
to spread-disease
if infected? [
ask turtles-on neighbors4 [
if not infected? and not immune? [
if random-float 1 < 0.2 [ ; Infection rate
set infected? true
set color red
]
]
]
]
end
; Turtles recover from disease
to recover
if infected? [
set days-infected days-infected + 1
if days-infected > 10 [
set infected? false
set immune? true
set color green
]
]
end
; Apply vaccination
to vaccinate
ask n-of 50 turtles [
if not infected? [
set immune? true
set color green
]
]
end
; Apply quarantine
to quarantine
ask turtles with [infected?] [
setxy random-xcor random-ycor
ask patch-here [set pcolor black]
]
end
Explanation
This model simulates the spread of a contagious disease within a population of turtles. The turtles can be in one of three states: susceptible (blue), infected (red), or immune (green). The disease spreads through contact with infected turtles, and infected turtles can recover and become immune after a certain period. The model also includes functions for vaccination and quarantine to observe their effects on disease spread.
