Although we are not working directly on the spread of COVID-19 in neighborhoods, the above program is a computational model and is similar to what we will be using to create our model for research. This is a great practice model and a wonderful way to experiment with a computational model. So, just for now, imagine that you are observing a neighborhood using a drone that is hovering over the roof tops. Each green patch represents a house. A blue patch represents a house with positive COVID-19.
Play around with the model. Try to make some observations of what is happening.
