Altering Network Connections
Note: in order to run the simulation referred to in this slide, go here, to the Java Applet version. You will be directed to download the latest version of the Java plug-in.
In this slide, we recreate the same simulation, including the semi-random network connections. Thus, simply clicking "Go" should produce results similar to those in the previous slide.
The difference is that you - the user - are allowed to alter the network connections, just like in the main Simulator console. To do that, click and drag the mouse between the two agents that you would like to connect or disconnect. Note that the total number of links is displayed below the graph. It is reset to the original 50 every time you press the "Restart" button.
Reducing the total number of connections certainly helps eradicate the infection. For instance, if you remove about 10 links throughout the network, the defect will almost certainly die out after the first 100 steps. Conversely, increasing the network's connectivity makes it more difficult to keep the deficiency under control.
However, perhaps it is possible to keep the total number of connections intact, but rearrange them in such a way that helps the situation without disconnecting the graph. In the next slide, we present just such an arrangement, and offer the intuition behind its effect.
