Reasoning about unpredicted change and explicit time

no code implementations9 Jul 2024 Florence Dupin de Saint-Cyr, Jérôme Lang

Reasoning about unpredicted change consists in explaining observations by events; we propose here an approach for explaining time-stamped observations by surprises, which are simple events consisting in the change of the truth value of a fluent.

Reasoning About Action and Change

no code implementations27 Jun 2024 Florence Dupin de Saint-Cyr, Andreas Herzig, Jérôme Lang, Pierre Marquis

The purpose of this book is to provide an overview of AI research, ranging from basic work to interfaces and applications, with as much emphasis on results as on current issues.

Thou Shalt not Pick all Items if Thou are First: of Strategyproof and Fair Picking Sequences

no code implementations11 Jan 2023 Sylvain Bouveret, Hugo Gilbert, Jérôme Lang, Guillaume Méroué

When allocating indivisible items to agents, it is known that the only strategyproof mechanisms that satisfy a set of rather mild conditions are constrained serial dictatorships: given a fixed order over agents, at each step the designated agent chooses a given number of items (depending on her position in the sequence).

Multi-winner Approval Voting Goes Epistemic

1 code implementation17 Jan 2022 Tahar Allouche, Jérôme Lang, Florian Yger

Epistemic voting interprets votes as noisy signals about a ground truth.

Truth-tracking via Approval Voting: Size Matters

1 code implementation7 Dec 2021 Tahar Allouche, Jérôme Lang, Florian Yger

Epistemic social choice aims at unveiling a hidden ground truth given votes, which are interpreted as noisy signals about it.

Online Selection of Diverse Committees

no code implementations19 May 2021 Virginie Do, Jamal Atif, Jérôme Lang, Nicolas Usunier

Citizens' assemblies need to represent subpopulations according to their proportions in the general population.

Agenda Separability in Judgment Aggregation

no code implementations22 Apr 2016 Jérôme Lang, Marija Slavkovik, Srdjan Vesic

One of the better studied properties for operators in judgment aggregation is independence, which essentially dictates that the collective judgment on one issue should not depend on the individual judgments given on some other issue(s) in the same agenda.

Boolean Hedonic Games

no code implementations23 Sep 2015 Haris Aziz, Paul Harrenstein, Jérôme Lang, Michael Wooldridge

The assumption of dichotomous preferences means that, additionally, each player's preference relation partitions the set of coalitions of which that player is a member into just two equivalence classes: satisfactory and unsatisfactory.


New Results on Equilibria in Strategic Candidacy

no code implementations7 Jun 2013 Jérôme Lang, Nicolas Maudet, Maria Polukarov, Alice Cohen-Hadria

For four candidates, the message is, roughly, that most scoring rules (with the exception of Borda) do not guarantee the existence of a pure Nash equilibrium but that Condorcet-consistent rules, for an odd number of voters, do.
