Thus, the time required to […]

In my last blog, I investigated the time taken for a giant component to develop in a social network.In that experiment, when the largest component contained the majority of people in the population, I stopped the simulation and recorded the time taken. If I were to continue the simulation, we’ll observe that the giant component […]
