Manipulating Opinion Diffusion in Social Networks

Robert Bredereck (University of Oxford)

We consider opinion diffusion in binary influence networks, where at
each step one or more agents update their opinions so as to be in
agreement with the majority of their neighbors. We consider several ways
of manipulating the majority opinion in a stable outcome, such as
bribing agents, adding/deleting links, and changing the order of
updates, and investigate the computational complexity of the associated
problems, identifying tractable and intractable cases.
