(A) Schematic of the generalized model. Parameters summarized in Table 3. (B) Reverse cumulative distributions obtained from simulations for different values of (left, middle, right) and (different colored lines within each panel). Increasing aggregation produces a plateau if the aggregation depends strongly enough on cluster size. (C) The plateau arises only in stochastic simulation of finite systems with size-dependent aggregation. Solid lines are stochastic simulations, dashed lines are the result of numerically integrating the master equation. Parameters: = 0.5 hr-1, , hr-1, , hr-1, , and the number of simulation was replicates = 150 per parameter set. For each value of , we considered values of 0 (no aggregation) and then varied α logarithmically, with the following (min, max) values for : (−4,–2) for , (−4.5,–2.5) for , and (−5,–3) for .
