Three power-law classes characterized by the power-law exponents 3/2, 2 and 5/2 are identified and the process is generalized to networks. In the network context the merging can be viewed as a consequence of optimization related to more efficient signaling.Physica A: Statistical Mechanics and its Applications, In PressDisordered Systems and Neural NetworksStatistical Mechanicstext
