A society is a medium with a complex structure of one-to-one relations between people. Those could be relations between friends, wife–husband relationships, relations between business partners, and so on. At a certain level of analysis, a society can be regarded as a gigantic maze constituted...

In the Cont–Bouchaud model [cond-mat/9712318] of stock markets, percolation clusters act as buying or selling investors and their statistics controls that of the price variations. Rather than fixing the concentration controlling each cluster connectivity artificially at or close to the...

Monte Carlo simulations are investigated to study the effects of the nutrient releasing source (NRS) on fractal patterns developed by a generalized dynamic fractal growth model (GDFGM). The morphology of the simulated structures reveals, in cylinder geometry, a strong correlation with the source...

The partitioning of random graphs is investigated numerically using “simulated annealing” and “extremal optimization”. While generally in an NP-hard problem, it is shown that the optimization of the graph partitions is particularly difficult for sparse graphs with average connectivities...
