Optimal (degree+1)-Coloring in Congested Clique (2023)
Presentation / Conference Contribution
Coy, S., Czumaj, A., Davies, P., & Mishra, G. (2023, July). Optimal (degree+1)-Coloring in Congested Clique. Presented at ICALP 2023: 50th EATCS International Colloquium on Automata, Languages and Programming, Paderborn, Germany

We consider the distributed complexity of the (degree+1)-list coloring problem, in which each node u of degree d(u) is assigned a palette of d(u) + 1 colors, and the goal is to find a proper coloring using these color palettes. The (degree+1)-list co... Read More about Optimal (degree+1)-Coloring in Congested Clique.

Uniting General-Graph and Geometric-Based Radio Networks via Independence Number Parametrization (2023)
Presentation / Conference Contribution
Davies, P. (2023, June). Uniting General-Graph and Geometric-Based Radio Networks via Independence Number Parametrization. Presented at PODC 2023: ACM Symposium on Principles of Distributed Computing, Orlando, Florida

In the study of radio networks, the tasks of broadcasting (propagating a message throughout the network) and leader election (having the network agree on a node to designate ‘leader’) are two of the most fundamental global problems, and have a long h...

Optimal Message-Passing with Noisy Beeps (2023)
Presentation / Conference Contribution
Davies, P. (2023, June). Optimal Message-Passing with Noisy Beeps. Presented at PODC 2023: ACM Symposium on Principles of Distributed Computing, Orlando, Florida

Beeping models are models for networks of weak devices, such as sensor networks or biological networks. In these networks, nodes are allowed to communicate only via emitting beeps: unary pulses of energy. Listening nodes only the capability of carrie...

Improved Distributed Algorithms for the Lovász Local Lemma and Edge Coloring (2023)
Presentation / Conference Contribution
Davies, P. (2023, January). Improved Distributed Algorithms for the Lovász Local Lemma and Edge Coloring. Presented at ACM-SIAM Symposium on Discrete Algorithms (SODA23), Florence, Italy

The Lovász Local Lemma is a classic result in probability theory that is often used to prove the existence of combinatorial objects via the probabilistic method. In its simplest form, it states that if we have n ‘bad events’, each of which occurs wit... Read More about Improved Distributed Algorithms for the Lovász Local Lemma and Edge Coloring.
