Social learning moderates the tradeoffs between efficiency, stability, and equity in group foraging
Collective foragers, from animals to robotic swarms, must balance exploration and exploitation to locate sparse resources efficiently. While social learning is known to facilitate this balance, how th...

Graph entropy, degree assortativity, and hierarchical structures in networks
We connect several notions relating the structural and dynamical properties of a graph. Among them are the topological entropy coming from the vertex shift, which is related to the spectral radius of ...
