no code implementations31 Jul 2023 Timothy Parker, Umberto Grandi, Emiliano Lorini

This can be used in a multi-agent planning setting to allow agents to anticipate responsibility in the plans they consider.

Logic-Based Ethical Planning

no code implementations1 Jun 2022 Umberto Grandi, Emiliano Lorini, Timothy Parker, Rachid Alami

In this paper we propose a framework for ethical decision making in the context of planning, with intended application to robotics.

Collective discrete optimisation as judgment aggregation

no code implementations1 Dec 2021 Linus Boes, Rachael Colley, Umberto Grandi, Jerome Lang, Arianna Novaro

Many important collective decision-making problems can be seen as multi-agent versions of discrete optimisation problems.

Unravelling multi-agent ranked delegations

no code implementations25 Nov 2021 Rachael Colley, Umberto Grandi, Arianna Novaro

We introduce a voting model with multi-agent ranked delegations.

Social Choice Methods for Database Aggregation

no code implementations22 Jul 2019 Francesco Belardinelli, Umberto Grandi

Knowledge can be represented compactly in multiple ways, from a set of propositional formulas, to a Kripke model, to a database.

Aggregation in Value-Based Argumentation Frameworks

no code implementations22 Jul 2019 Grzegorz Lisowski, Sylvie Doutre, Umberto Grandi

Value-based argumentation enhances a classical abstract argumentation graph - in which arguments are modelled as nodes connected by directed arrows called attacks - with labels on arguments, called values, and an ordering on values, called audience, to provide a more fine-grained justification of the attack relation.

Agent-Mediated Social Choice

no code implementations19 Jun 2018 Umberto Grandi

Direct democracy is often proposed as a possible solution to the 21st-century problems of democracy.

Relaxing Exclusive Control in Boolean Games

no code implementations27 Jul 2017 Francesco Belardinelli, Umberto Grandi, Andreas Herzig, Dominique Longin, Emiliano Lorini, Arianna Novaro, Laurent Perrussel

We introduce Concurrent Game Structures with Shared Propositional Control (CGS-SPC) and show that they ac- count for several classes of repeated games, including iterated boolean games, influence games, and aggregation games.

Graph Aggregation

no code implementations13 Sep 2016 Ulle Endriss, Umberto Grandi

Graph aggregation is the process of computing a single output graph that constitutes a good compromise between several input graphs, each provided by a different source.

Strategic disclosure of opinions on a social network

no code implementations5 Feb 2016 Umberto Grandi, Emiliano Lorini, Laurent Perrussel

We study the strategic aspects of social influence in a society of agents linked by a trust network, introducing a new class of games called games of influence.
