  In a process of aggregation, a finite number of particles merge irreversibly
to create growing clusters. In this work, impact of particular initial
conditions: monodisperse, power-law, exponential, and inspired by condensation
nuclei was tested against several aggregation processes: constant, additive,
product, electrorheological, anti-social, Berry's, Brownian, shear, and
gravitational kernels. Coagulating systems consisting of a thousand monomers
were observed in the late time of the evolution, for the moment when only fifty
clusters were left in the system. In this way, the impact of particular initial
condition was revealed in relation to other initial conditions. Several
similarities between different kernels were observed, among others, strong
correspondence between the constant and the Brownian kernel was confirmed. In
case of the product kernel, unexpected behaviour related to the condensation
nuclei initial conditions was revealed and explained. According to the results,
it is doubtful that a phase transition can be triggered by appropriate setting
of initial condition.
