the project

Collective decision methods (elections, participatory budgeting, matching, comittee voting, judgment aggregation…), as traditionally studied in the field of (computational) social choice, do not take into account the existence of a network relating the decision-makers. The objective of this ANR jeune chercheur/jeune chercheuse project is the conception of algorithms for opinion diffusion and vote computation in the presence of a social network, and its assessment in terms of computational and communication complexity, axiomatic properties, including game-theoretic ones such as resistance to strategic actions by voters or external agents.

The SCONE project is conducted at the Institut d’Informatique de Toulouse (IRIT) at Université Toulouse 1 Capitole, from 2019 to 2023.
