  In this paper we propose a novel control approach for opinion dynamics on
evolving networks. The controls modify the strength of connections in the
network, rather than influencing opinions directly, with the overall goal of
steering the population towards a target opinion. This requires that the social
network remains sufficiently connected, the population does not break into
separate opinion clusters, and that the target opinion remains accessible. We
present several approaches to addressing these challenges, considering
questions of controllability, instantaneous control and optimal control. Each
of these approaches provides a different view on the complex relationship
between opinion and network dynamics and raises interesting questions for
future research.
