Agreement, Diversity, and Polarization Indices for Approval Elections
Piotr Faliszewski, Jitka Mertlová, Krzysztof Sornat +2
An index is a function that given an election outputs a value between 0 and 1, indicating the extent to which this election has a particular feature. We seek indices that capture a…
Outer Diversity of Structured Domains
Piotr Faliszewski, Krzysztof Sornat, Stanisław Szufa +1
An ordinal preference domain is a subset of preference orders that the voters are allowed to cast in an election. We introduce and study the notion of outer diversity of a domain a…
How Similar Are Two Elections?
Piotr Faliszewski, Piotr Skowron, Arkadii Slinko +3
We introduce and study isomorphic distances between ordinal elections (with the same numbers of candidates and voters). The main feature of these distances is that they are invaria…
Participatory Budgeting Project Strength via Candidate Control
Piotr Faliszewski, Łukasz Janeczko, Dušan Knop +4
We study the complexity of candidate control in participatory budgeting elections. The goal of constructive candidate control is to ensure that a given candidate wins by either add…
Diversity of Structured Domains via k-Kemeny Scores
Piotr Faliszewski, Krzysztof Sornat, Stanisław Szufa +1
In the k-Kemeny problem, we are given an ordinal election, i.e., a collection of votes ranking the candidates from best to worst, and we seek the smallest number of swaps of adjace…
An Experimental Comparison of Multiwinner Voting Rules on Approval Elections
Piotr Faliszewski, Martin Lackner, Krzysztof Sornat +1
In this paper, we experimentally compare major approval-based multiwinner voting rules. To this end, we define a measure of similarity between two equal-sized committees subject to…
