In the initial step, the analysis of the adjacency matrix of the entire system determines the number of aggregates of each size, n. This is achieved by transforming the adjacency matrix of the system into a block-diagonal form, where each diagonal block represents the individual adjacency matrix of a distinct aggregate in the system. The dimension of this matrix determines the size of the aggregate. In this way, from the number of blocks of identical dimensions and the total number of blocks, we can calculate the population of aggregates of varying sizes.
