Consensus Reaching Through Adding Minimum Interactions

In this chapter, we consider the optimization-based consensus model to reach a consensus by adding minimum interactions in the SNDG model. Then, we propose algorithms to obtain the optimal solution using two steps: network partition and edge addition. Furthermore, we extend the optimization-based consensus model to manage the consensus with an established target. Finally, we provide numerical analysis to aid in understanding the optimization-based consensus model in the SNDG model.
