Moduleco 2 - Concepts of the multi-agent's dynamics 2.1.c Diffusion and Criticality in Marketing : Neural Adaptive Social Network

In this model, social network is formalized as a neural network with a small degree of connectivity (say in average 1,5%). After learning, some people will became the center of larger network (say in average 10%) as act as kind of "leader of opinion". as a result, we have an inhomogeneous process of diffusion, with classical S- shaped curve, but non classical increments, which are following a power law distribution.
