Algorithms for Influence Maximization in Socio-Physical Networks
Hemant Gehlot, Shreyas Sundaram, Satish V. Ukkusuri
Given a directed graph (representing a social network), the influence maximization problem is to find k nodes which, when influenced (or activated), would maximize the number of re…
Ignoring Extreme Opinions in Complex Networks: The Impact of Heterogeneous Thresholds
Shreyas Sundaram
We consider a class of opinion dynamics on networks where at each time-step, each node in the network disregards the opinions of a certain number of its most extreme neighbors and…
Robustness and Algebraic Connectivity of Random Interdependent Networks
Ebrahim Moradi Shahrivar, Mohammad Pirani, Shreyas Sundaram
We investigate certain structural properties of random interdependent networks. We start by studying a property known as -robustness, which is a strong indicator of the ability…
Robustness of Complex Networks with Implications for Consensus and Contagion
Haotian Zhang, Elaheh Fata, Shreyas Sundaram
We study a graph-theoretic property known as robustness, which plays a key role in certain classes of dynamics on networks (such as resilient consensus, contagion and bootstrap per…
Robustness of Information Diffusion Algorithms to Locally Bounded Adversaries
Haotian Zhang, Shreyas Sundaram
We consider the problem of diffusing information in networks that contain malicious nodes. We assume that each normal node in the network has no knowledge of the network topology o…
