Determining possible and necessary winners given partial orders

L Xia, V Conitzer - Journal of Artificial Intelligence Research, 2011 - jair.org
Usually a voting rule requires agents to give their preferences as linear orders. However, in
some cases it is impractical for an agent to give a linear order over all the alternatives. It has …

Complexity of manipulation and bribery in judgment aggregation for uniform premise-based quota rules

D Baumeister, G Erdélyi, OJ Erdélyi, J Rothe - Mathematical Social …, 2015 - Elsevier
Abstract Endriss et al.(2012) initiated the complexity-theoretic study of problems related to
judgment aggregation. We extend their results on the manipulation of two specific judgment …

Cloning in elections: Finding the possible winners

E Elkind, P Faliszewski, A Slinko - Journal of Artificial Intelligence Research, 2011 - jair.org
We consider the problem of manipulating elections by cloning candidates. In our model, a
manipulator can replace each candidate c by several clones, ie, new candidates that are so …

Large-scale election campaigns: Combinatorial shift bribery

R Bredereck, P Faliszewski, R Niedermeier… - Journal of Artificial …, 2016 - jair.org
We study the complexity of a combinatorial variant of the SHIFT BRIBERY problem in
elections. In the standard SHIFT BRIBERY problem, we are given an election where each …

Algorithms for destructive shift bribery

A Kaczmarczyk, P Faliszewski - Autonomous Agents and Multi-Agent …, 2019 - Springer
We study the complexity of Destructive Shift Bribery. In this problem, we are given an
election with a set of candidates and a set of voters (each ranking the candidates from the …

Multiwinner rules with variable number of winners

P Faliszewski, A Slinko, N Talmon - ECAI 2020, 2020 - ebooks.iospress.nl
We consider voting rules for approval-based elections that select committees whose size is
not predetermined. Unlike the study of rules that output committees with a predetermined …

The complexity of bribery and control in group identification

G Erdélyi, C Reger, Y Yang - Autonomous Agents and Multi-Agent …, 2020 - Springer
The goal of this paper is to analyze the complexity of constructive/destructive bribery and
destructive control in the framework of group identification. Group identification applies to …

On the complexity of bribery and manipulation in tournaments with uncertain information

N Mattei, J Goldsmith, A Klapper, M Mundhenk - Journal of Applied Logic, 2015 - Elsevier
We study the computational complexity of bribery and manipulation schemes for sports
tournaments with uncertain information. We introduce a general probabilistic model for multi …
