“…For general directed network topologies with self-loop, the sufficient conditions for consensus were closely related to the uniform quasi-strong connectivity of the graphs [23]. VOLUME 4, 2016 In the past few decades, various deformations of the De-Groot model have also been extensively studied [9], [14]- [16], [24], [25].
