Abstract: In discrete-time dynamics, it is frequently assumed that the transition probabilities (e.g., the recovery probability) are independent of the network structure. However, there is a lack of empirical evidence to support this claim in large time intervals. This paper presents the nonlinear relations between the rates (in continuous-time dynamics) and probabilities of the susceptible–infected–susceptible model on annealed and static networks. It is shown that the transition probabilities are affected not only by the rates and the time interval, but also by the network structure. The correctness of the nonlinear relations on networks is verified based on theoretical calculation and Monte Carlo simulation.
