Introduction Most of the talk/transportation systems of the veritable world can be represented as complex networks, in which the nodes are the elementary components of the system and the edges connect duet of nodes that mutuall y interact exchanging information. To quote ! a few examples: in the Internet the nodes are the routers and the edges (or arcs) are the cables connecting couples of routers; in an electrical world power grid the nodes are the substations (generators or distribution substations) and the edges are the contagious disease lines; in a city alley system the nodes are the crossings and the ?
