Lecture Notes on Voting Theory
Davide Grossi
These lecture notes have been developed for the course Computational Social Choice of the Artificial Intelligence MSc programme at the University of Groningen. They cover mathemati…
Credulous Acceptability, Poison Games and Modal Logic
Davide Grossi, Simon Rey
The Poison Game is a two-player game played on a graph in which one player can influence which edges the other player is able to traverse. It operationalizes the notion of existenc…
On the Graded Acceptability of Arguments in Abstract and Instantiated Argumentation
Davide Grossi, Sanjay Modgil
The paper develops a formal theory of the degree of justification of arguments, which relies solely on the structure of an argumentation framework, and which can be successfully in…
When Are Two Gossips the Same? Types of Communication in Epistemic Gossip Protocols
Krzysztof R. Apt, Davide Grossi, Wiebe van der Hoek
We provide an in-depth study of the knowledge-theoretic aspects of communication in so-called gossip protocols. Pairs of agents communicate by means of calls in order to spread inf…
On Rational Delegations in Liquid Democracy
Daan Bloembergen, Davide Grossi, Martin Lackner
Liquid democracy is a proxy voting method where proxies are delegable. We propose and study a game-theoretic model of liquid democracy to address the following question: when is it…
A Note on Nesting in Dyadic Deontic Logic
Agneau Belanyek, Davide Grossi, Wiebe van der Hoek
The paper reports on some results concerning Aqvist's dyadic logic known as system G, which is one of the most influential logics for reasoning with dyadic obligations ("it ought t…
Binary Voting with Delegable Proxy: An Analysis of Liquid Democracy
Zoé Christoff, Davide Grossi
The paper provides an analysis of the voting method known as delegable proxy voting, or liquid democracy. The analysis first positions liquid democracy within the theory of binary…
Liquid Democracy: An Analysis in Binary Aggregation and Diffusion
Zoé Christoff, Davide Grossi
The paper proposes an analysis of liquid democracy (or, delegable proxy voting) from the perspective of binary aggregation and of binary diffusion models. We show how liquid democr…
Epistemic Protocols for Distributed Gossiping
Krzysztof R. Apt, Davide Grossi, Wiebe van der Hoek
Gossip protocols aim at arriving, by means of point-to-point or group communications, at a situation in which all the agents know each other's secrets. We consider distributed goss…
Equilibrium Refinement through Negotiation in Binary Voting
Umberto Grandi, Davide Grossi, Paolo Turrini
We study voting games on binary issues, where voters hold an objective over the outcome of the collective decision and are allowed, before the vote takes place, to negotiate their…
Ceteris Paribus Structure in Logics of Game Forms
Davide Grossi, Emiliano Lorini, Francois Schwarzentruber
The article introduces a ceteris paribus modal logic interpreted on the equivalence classes induced by sets of propositional atoms. This logic is used to embed two logics of agency…
