Translated by. Hi Munzir, since you are looking to model population infection of a disease, an alternative to a "real-time" approach is a simulated approach that utilizes arbitrary time-steps. A: Math. Preferential attachment is an example of a positive feedback cycle where initially random variations one node initially having more links or having started accumulating links earlier than another are automatically reinforced, thus greatly magnifying differences. Both growth and preferential attachment exist widely in real networks.
