Restless reachability problems in temporal graphs

Suhas Thejaswi, Juho Lauri, Aristides Gionis

We study a family of reachability problems under waiting-time restrictions in temporal and vertex-colored temporal graphs. Given a temporal graph and a set of source vertices, we f…

Finding large balanced subgraphs in signed networks

Bruno Ordozgoiti, Antonis Matakos, Aristides Gionis

Signed networks are graphs whose edges are labelled with either a positive or a negative sign, and can be used to capture nuances in interactions that are missed by their unsigned…

Improved mixing time for k-subgraph sampling

Ryuta Matsuno, Aristides Gionis

Understanding the local structure of a graph provides valuable insights about the underlying phenomena from which the graph has originated. Sampling and examining k-subgraphs is a…
