@#$#@#$#@## WHAT IS IT?

Disease Solo is a one-player version of the HubNet activity Disease. It simulates the spread of a disease through a population. One agent in the population isa person controlled by the user; the others are "androids" controlled by the computer.

## HOW IT WORKS

The user controls the blue agent via the buttons and slider on the right side ofthe view. The infection is started by pressing the "infect" button.

Sick agents are indicated by a red circle.

Androids can move using a few different simple strategies. By default they simply move randomly, however, using the AVOID? and CHASE? switches you can indicate


9/23

that uninfected androids should run from infected ones or infected androids should chase uninfected ones.

The person may also catch the infection.

Healthy "agents" on the same patch as sick agents have an INFECTION-CHANCE chance of becoming ill.

## HOW TO USE IT

### Buttons

SETUP/CLEAR - sets up the world and clears plots.SETUP/KEEP - sets up the world without clearing the plot; this lets you compareresults from different runs.GO - runs the simulation.INFECT - infects one of the androids

### Sliders

NUM-ANDROIDS - determines how many androids are created at setupINFECTION-CHANCE - a healthy agent's chance at every time step to become sick ifit is on the same patch as an infected agent

### Monitors

NUMBER SICK - the number of sick agents

### Plots

NUMBER SICK - the number of sick agents versus time

### Switches

AVOID? - when this switch is on each uninfected android checks all four directions to see if it can move to a patch that is safe from infected agents.CHASE? - when this switch is on each infected androids checks all four direction

s to see if it can infect another agent.

### User controls

UP, DOWN, LEFT, and RIGHT - move the person around the world, STEP-SIZE determines how far the person moves each time one of the control buttons is pressed.

## THINGS TO NOTICE

Think about how the plot will change if you alter a parameter. Altering the infection chance will have different effects on the plot.

## THINGS TO TRY

Do several runs of the model and record a data set for each one by using the setup/keep button. Compare the different resulting plots.

What happens to the plot as you do runs with more and more androids?

## EXTENDING THE MODEL

Currently, the agents remain sick once they're infected. How would the shape ofthe plot change if agents eventually healed? If, after healing, they were immu


10/23

ne to the disease, or could still spread the disease, how would the dynamics bealtered?

The user has a distinct advantage in this version of the model (assuming that the goal is either not to become infected, or to infect others), as the user can see the entire world and the androids can only see one patch ahead of them. Tryto even out the playing field by giving the androids a larger field of vision.

Determining the first agent who is infected may impact the way disease spreads through the population. Try changing the target of the first infection so it canbe determined by the user.

## NETLOGO FEATURES

You can use the keyboard to control the person. To activate the keyboard shortcuts for the movement button, either hide the command center or click in the white background.

The plot uses temporary plot pens, rather than a fixed set of permanent plot pens, so you can use the setup/keep button to overlay as many runs as you want.
