The canvas below represents either a town, a city, a district or even a whole country. This "world" is populated by "Blobs" and like every other world consists of population centers.
A Blob is a stand-in for a human. It has two characteristics (or properties). A size and an infection radius. I am going to go out on a limb and assume that these are self explanatory terms. A human travels from his "home" location to a population center and back home each day.
A Population Center is a stand-in for somewhere humans go to during everyday of their existence. It could be a school, a workplace, or even a movie theatre. Population centers of of two types.
- Primary: Where a human MUST visit each day. This is like a school or a workplace
- Secondary: Where a human only visits once a while. This is akin to a coffee shop, or grocery, or movie theatre.
At the start of every simulation only one Blob is infected. Everytime this Blob comes within the infectivity radius of
another Blob the infection spreads.
Infections also have a fatality rate. A higher fatality rate results in the Blob "Dying" sooner.
It is also possible to socially distance Blobs. To our surprise this indeed results in the more Blobs "Surviving".
Each parameter is controlled with sliders below the simulation. We were most surprised with controlling the Social Distancing Complaince Rate slider. Social Distancing isn't supposed to curb infections; it only slows the infection rate at a rate which hospitals can cope up with. And this is exactly what happens in the simulation.
| Variable | Value Range | Value |
| Population Density | 50 - 500 | |
| Blob Size | 2 - 10 | |
| Infectivity (R0) | 1 - 20 | |
| Social Distancing Complaince Rate | 0 - 100 | |
| Fatality Rate | 0.01 - 1 | |
