Problem

These two papers both try to describe the human or social behavior by modelling, though the ways to modelling are different. The first paper tries to apply an unseen network to a visible result. The result could be virus propagation, news spread, etc. The model is to maximize the possibility of the set of cascades over all possible graphs of at most k edges. Such graph is considered as the most likelihood underlying graph. The second paper, uses maths, computer simulation and real data to prove that, in the assumption of people following the pattern of doing tasks with highest priority first, will lead to the conclusion that most of the tasks will be rapidly executed and a few will have long waiting times, which is called the heavy-tail process.
