# 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.

## Designing truthful mecanism

summary: In this presentation, we will focus on the generalization of knapsack budgeting. Given a set of projects and a budget, each voter selects a subset of projects; we want to maximize social welfare. Different measures can describe this (maximizing the minimum utility of the players, maximizing the sum of ...

## Classification of truth revealing social choice algorithms

summary: The talk will be on the field of social choices. A group of players

want to choose a subset of a set of objects respecting some properties

(maximal weight of the subset, maximal amount of objects in the subset, ...).
To do so, they vote and use a social choice ...

## Block gluing in Hom shifts and path reconfiguration in graphs

summary: We study some tilings spaces that are defined from graph homomorphisms, called Hom shifts. Compared to general tiling spaces, they look the same in every direction (invariance by rotation and symmetry) and many undecidable problems or questions in tiling spaces seem to become easier for these objects, using graph-theoretical ...
