Sharp Thresholds for Temporal Motifs and Doubling Time in Random Temporal Graphs

Henry Austin, George B. Mertzios, Paul G. Spirakis

In this paper we study two natural models of random temporal graphs. In the first, the continuous model, each edge is assigned labels, each drawn uniformly at random from…

Enumerating Inclusion-Maximal Arithmetic Progressions

Brian Bemman, Maximilien Gadouleau, Oliver W. Gnilke +1

We present a simple enumeration algorithm for solving a problem from mathematical and computational music analysi…

Round-Delayed Amnesiac Flooding

Oluwatobi Alafin, George B. Mertzios, Paul G. Spirakis

We present a comprehensive analysis of Round-Delayed Amnesiac Flooding (RDAF), a variant of Amnesiac Flooding that introduces round-based asynchrony through adversarial delays. We…

Maintaining Bipartite Colourings on Temporal Graphs on a Budget

Duncan Adamson, George B. Mertzios, Paul G. Spirakis

Graph colouring is a fundamental problem for networks, serving as a tool for avoiding conflicts via symmetry breaking, for example, avoiding multiple computer processes simultaneou…

Amnesiac Flooding: Easy to break, hard to escape

Henry Austin, Maximilien Gadouleau, George B. Mertzios +1

Broadcast is a central problem in distributed computing. Recently, Hussak and Trehan [PODC'19/DC'23] proposed a stateless broadcasting protocol (Amnesiac Flooding), which was surpr…

Temporal Graph Realization With Bounded Stretch

George B. Mertzios, Hendrik Molter, Nils Morawietz +1

A periodic temporal graph, in its simplest form, is a graph in which every edge appears exactly once in the first time steps, and then it reappears recurrently every time…
