A notion of robustness in complex networks
H Zhang, E Fata, S Sundaram - IEEE Transactions on Control …, 2015 - ieeexplore.ieee.org
We consider a graph-theoretic property known as r-robustness which plays a key role in a
class of consensus (or opinion) dynamics where each node ignores its most extreme …

Growing a graph matching from a handful of seeds
In many graph--mining problems, two networks from different domains have to be matched.
In the absence of reliable node attributes, graph matching has to rely on only the link …
