The focus of this article is to study the effect of diffusion on the dynamics of distributions of particles adsorbed on a surface. The dynamics of particle distributions can be viewed as the change of configurations with time. The configurations are created by adsorption, desorption, or diffusion. This kind of study is not only important for surface-science studies, but it is also very useful in the study of complex system in general.

One important aspect of political dynamics is the fact that people are taking sides. There are times where the available sides are very limited, and the people's preferences are very clear. But there are also times where not only the number of sides is not clear, but the people also keep on changing sides all the time. In our simulation, we define the condition where the number of political sides are limited, and the people's choice is very clear and consistent as the situation where the temperature is low. On the other hand, we define the the situation when the people's choice is always changing, and the preferential attachment is many, as the situation where the temperature is high. This situation is illustrated by Fig. 1.



In many studies it has been shown that connectivity actually increase the probability of damage spreading, hence contributing to the instability of the system. In this report we take a different stand by making a differentiation between positive and negative connectivity.
