We refer to social dynamics as collective group dynamics with emergence of self-organization from simple interaction rule of “social type”. Examples include opinion dynamics as in the Hegselmann-Krause model or alignment dynamic as in the Cucker-Smale models. In particular, the interest is on sparse control algorithms to lead a group to consensus. Applications include modeling of animal groups.
