Identifying Imperfect Clones in Elections

Piotr Faliszewski, Lukasz Janeczko, Grzegorz Lisowski +2

A perfect clone in an ordinal election (i.e., an election where the voters rank the candidates in a strict linear order) is a set of candidates that each voter ranks consecutively.…

Project Submission Games in Participatory Budgeting

Piotr Faliszewski, Łukasz Janeczko, Andrzej Kaczmarczyk +2

We introduce the framework of project submission games, capturing the behavior of project proposers in participatory budgeting (and multiwinner elections). Here, each proposer subm…

Guide to Numerical Experiments on Elections in Computational Social Choice

Niclas Boehmer, Piotr Faliszewski, Łukasz Janeczko +7

We analyze how numerical experiments regarding elections were conducted within the computational social choice literature (focusing on papers published in the IJCAI, AAAI, and AAMA…

Evaluation of Project Performance in Participatory Budgeting

Niclas Boehmer, Piotr Faliszewski, Łukasz Janeczko +5

We study ways of evaluating the performance of losing projects in participatory budgeting (PB) elections by seeking actions that would have led to their victory. We focus on loweri…

Robustness of Participatory Budgeting Outcomes: Complexity and Experiments

Niclas Boehmer, Piotr Faliszewski, Łukasz Janeczko +1

We study the robustness of approval-based participatory budgeting (PB) rules to random noise in the votes. Our contributions are twofold. First, we study the computational complexi…

Ties in Multiwinner Approval Voting

Łukasz Janeczko, Piotr Faliszewski

We study the complexity of deciding whether there is a tie in a given approval-based multiwinner election, as well as the complexity of counting tied winning committees. We conside…

Properties of Position Matrices and Their Elections

Niclas Boehmer, Jin-Yi Cai, Piotr Faliszewski +4

We study the properties of elections that have a given position matrix (in such elections each candidate is ranked on each position by a number of voters specified in the matrix).…

The Complexity of Proportionality Degree in Committee Elections

Łukasz Janeczko, Piotr Faliszewski

Over the last few years, researchers have put significant effort into understanding of the notion of proportional representation in committee election. In particular, recently they…

How to Sample Approval Elections?

Stanisław Szufa, Piotr Faliszewski, Łukasz Janeczko +4

We study the multifaceted question of how to sample approval elections in a meaningful way. Our analysis aims to discern the properties of various statistical cultures (both establ…
