An important question prompted by the modularity of these networks is whether. Its low memory requirements, together with its linear speedup, make it really efficient, even on dense, highly interconnected networks. Percolation, in its most general interpretation, refers to the flow of something a physical agent, data or information in a network, possibly accompanied by some nonlinear dynamical.
