Fast Landmark Reconfiguration for Highway Cover Indexes
Conference Paper
David Coudert, Andrea D Ascenzo, Mattia d'Emidio, Giuseppe F Italiano
The highway cover labeling (HCL) is an indexing method for weighted digraphs that enables fast queries on important graph properties such as distances and constrained shortest paths. Originally introduced by [Farhan et al., EDBT 2019], the HCL has gained popularity in the field…
Conception et implémentation d'une ontologie des facteurs psychosociaux liés aux attitudes et comportements alimentaires dysfonctionnels chez les sportifs
Conference Paper
Sara Taoufiq, Molka Tounsi Dhouib, Amandine Daubresse, Catherine Faron, Meggy Hayotte, Stéphanie Scoffier-Mériaux
Les attitudes et comportements alimentaires dysfonctionnels (ACAD) représentent des phénomènes complexes liés à de multiples facteurs psychosociaux dans le contexte sportif. Les recherches actuelles dans ce domaine présentent une forte complexité et des inconsistances…
Algorithms and Lower Bounds for the Maximum Overlap of Two Polygons Under Translation
Conference Paper
Mikkel Abrahamsen, Sujoy Bhore, Maike Buchin, Jacobus Conradi, Ce Jin, André Nusser, Carolin Rehs
A fundamental problem in shape matching and geometric similarity is computing the maximum area overlap between two polygons under translation. For general simple polygons, the best-known algorithm runs in $O((nm)^2 \log(nm))$ time [Mount, Silverman, Wu 96], where $n$ and $m$…
Toughness Properties of Arbitrarily Partitionable Graphs
Journal Article
Julien Bensmail
Drawing inspiration from a well-known conjecture of Chv\'atal on a toughness threshold guaranteeing graph Hamiltonicity, we investigate toughness properties of so-called arbitrarily partitionable (AP) graphs, which are those graphs that can be partitioned into arbitrarily many…
Neighbor selection strategies in the wild for CDN/V2V WebRTC live streaming: Can we learn what a good neighbor is?
Journal Article
Zhejiayu Ma, Frédéric Giroire, Guillaume Urvoy-Keller, Soufiane Rouibia
A hybrid CDN/Viewer-to-Viewer (V2V) architecture is an attractive solution for HTTP (HLS) and MPEG-DASH-based live streaming providers. It combines a traditional CDN with a V2V overlay for exchanging video fragments, reducing the CDN costs while maintaining the quality of…
The Harmonious Coloring Game
Journal Article
Cláudia Linhares Sales, Thiago Marcilon, Nicolas Martins, Nicolas Nisse, Rudini Sampaio
A harmonious k-coloring of a graph G is a 2-distance proper k-coloring of its vertices such that each edge is uniquely identified by the colors of its endpoints. Here, we introduce its game version: the harmonious coloring game. In this two-player game, Alice and Bob…
