GALaC team at LRI, Paris-Sud
GALaC is a research group at LRI, Paris-Sud University. We are focused on graph theory, combinatorics and network distributed systems algorithmic.
A global presentation of research activities in GALaC was made in 2013 for the AERES evaluation: Slides AERES 2013 and projet.

Descentes et inversions dans les permutations
summary: On peut identifier une permutation avec son ensemble d'inversions. Si deux ensembles d'inversions sont disjoints et que leur union est aussi un ensemble d'inversions, on obtient donc une nouvelle permutation. C'est un cas assez rare et intéressant et on démontre un résultat sur le nombre ...
Decision-Theoretic Approaches in Learning-Augmented Algorithms
summary: We initiate the systematic study of decision-theoretic metrics in the design and analysis of algorithms with machine-learned predictions. We introduce approaches based on both deterministic measures such as distance-based evaluation, that help us quantify how close the algorithm is to an ideal solution, as well as stochastic measures that ...
Packing many dominating sets in a graph
summary: Given a graph G, a dominating set of G is a subset of vertices S such that every vertex not in S is adjacent to at least one vertex in S. While classical studies focus on finding the smallest dominating set of G, our focus shifts to finding the ...
