the project (2019-2023)

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.
