Probabilistic Finite State Machines (PFSMs) describing the microscopic behaviour of an agent in average.
Here, the notation is a shorthand for (A) PFSM describing the basic commitment dynamics. Spontaneous transitions are represented by solid lines, interactive transitions by dashed lines. For a complete version with n + 1 states, see panel A in S1 Fig (B) PFSM describing the dynamics of activity change as agents switch from latent to interactive states. Latent states are indicated in grey, while changes in the activity state are represented by dash-dotted arrows. (C) PFSM describing the coupled dynamics of commitment and activity change. For a complete version with 2(n + 1) states, see panel B in S1 Fig.
