Optimally Frugal Foraging
O. Benichou, U. Bhat, P. L. Krapivsky +1
We introduce the \emph{frugal foraging} model in which a forager performs a discrete-time random walk on a lattice, where each site initially contains food units. The…
Structural Transitions in Dense Networks
R. Lambiotte, P. L. Krapivsky, U. Bhat +1
We introduce an evolving network model in which a new node attaches to a randomly selected target node and also to each of its neighbors with probability . The resulting network…
Exotic phase transitions of k-cores in clustered networks
Uttam Bhat, Munik Shrestha, Laurent Hébert-Dufresne
The giant -core --- maximal connected subgraph of a network where each node has at least neighbors --- is important in the study of phase transitions and in applications of…
Emergence of Clustering in an Acquaintance Model without Homophily
Uttam Bhat, P. L. Krapivsky, S. Redner
We introduce an agent-based acquaintance model in which social links are created by processes in which there is no explicit homophily. In spite of the homogeneous nature of the soc…
