Collective behavior & pseudo-stable states in complex networks dynamics
In every society there is a common question; what happens tomorrow, or what comes next? You cannot answer this question unless you gain insight on the A to Z of the hidden paths put forward for that society. But sometimes networks have to change in some paths in special conditions. Apparently in societies, although there are no external controllers, the societies do not evolve randomly. This evolution is self-organized in a sense that the system, in every evolving step, finds the lower energy state towards obtaining balance. As a matter of fact, a society consists of a collection of members that are not exactly independent of each other. In fact they might very much influence each other, in a sense that the evolution of societies take a trend that leads to the reduction of the stress between the members of the society. With this introduction I go ahead and state the aims of the present talk. My intention is to emphasis the characteristics and features of pseudo-stable (jammed) states. The question to be answered is that although we know that the balance state implies a minimum stress condition and hence a minimum energy state, why do the jammed (Local energy) states come in to play?
