Constrained Distributed Nonconvex Optimization over Time-varying Directed Graphs

IEEE Conference on Decision and Control, 2020
This paper addresses a class of constrained distributed nonconvex optimization problems involving univariate objective functions, considering time-varying directed networks. We propose a novel algorithm named Extended-CPCA (E-CPCA), exploiting the notion

Which Link Matters? Maintaining Connectivity of Uncertain Networks Under Adversarial Attack

IEEE Transactions on Mobile Computing
This article studies connectivity maintenance in uncertain networks under adversarial attack, where a defender conceals crucial links to prevent the largest connected component from being decomposed by an attacker. In contrast with its static counterpart,

Computing the Line Index of Balance Using Integer Programming Optimisation

arXiv.org, 2017
An important measure of signed graphs is the line index of balance which has applications in many fields. However, this graph-theoretic measure was underused for decades because of the inherent complexity in its computation which is closely related to ...
