A Generalization of the Minisum and Minimax Voting Methods
A Generalization of the Minisum and Minimax Voting Methods Shankar N. Sivarajan Undergraduate, Department of Physics Indian Institute of Science Bangalore 560 012, India [email protected] Faculty Advisor: Prof. Y. Narahari Deparment of Computer Science and Automation Revised Version: December 4, 2017 Abstract In this paper, we propose a family of approval voting-schemes for electing committees based on the preferences of voters. In our schemes, we calcu- late the vector of distances of the possible committees from each of the ballots and, for a given p-norm, choose the one that minimizes the magni- tude of the distance vector under that norm. The minisum and minimax methods suggested by previous authors and analyzed extensively in the literature naturally appear as special cases corresponding to p = 1 and p = 1; respectively. Supported by examples, we suggest that using a small value of p; such as 2 or 3, provides a good compromise between the minisum and minimax voting methods with regard to the weightage given to approvals and disapprovals. For large but finite p; our method reduces to finding the committee that covers the maximum number of voters, and this is far superior to the minimax method which is prone to ties. We also discuss extensions of our methods to ternary voting. 1 Introduction In this paper, we consider the problem of selecting a committee of k members out of n candidates based on preferences expressed by m voters. The most common way of conducting this election is to allow each voter to select his favorite candidate and vote for him/her, and we select the k candidates with the most number of votes. -
1 Introduction 2 Condorcet and Borda Tallies
1 Introduction General introduction goes here. 2 Condorcet and Borda Tallies 2.1 Definitions We are primarily interested in comparing the behaviors of two information aggregation methods, namely the Condorcet and Borda tallies. This interest is motivated by both historical and practical concerns: the relative merits of the two methods have been argued since the 18th century, and, although variations on the Borda tally are much more common in practice, there is a significant body of theoretical evidence that the Condorcet tally is in many cases superior. To begin, we provide formal definitions of both of these methods, and of a generalized information aggregation problem. An information aggregation problem, often referred to simply as a voting problem, is a problem which involves taking information from a number of disparate sources, and using this information to produce a single output. Problems of this type arise in numerous domains. In political science, they are common, occurring whenever voters cast votes which are used to decide 1 the outcome of some issue. Although less directly, they also occur in fields as diverse as control theory and cognitive science. Wherever there is a system which must coalesce information from its subsystems, there is potentially the need to balance conflicting information about a single topic. In any such circumstance, if there is not reason to trust any single source more than the others, the problem can be phrased as one of information aggregation. 2.1.1 Information Aggregation Problems To facilitate the formalization of these problems, we only consider cases in which a finite number of information sources (which shall henceforth be re- ferred to as voters) provide information regarding some contested issue. -
Stable Voting
Stable Voting Wesley H. Hollidayy and Eric Pacuitz y University of California, Berkeley ([email protected]) z University of Maryland ([email protected]) September 12, 2021 Abstract In this paper, we propose a new single-winner voting system using ranked ballots: Stable Voting. The motivating principle of Stable Voting is that if a candidate A would win without another candidate B in the election, and A beats B in a head-to-head majority comparison, then A should still win in the election with B included (unless there is another candidate A0 who has the same kind of claim to winning, in which case a tiebreaker may choose between A and A0). We call this principle Stability for Winners (with Tiebreaking). Stable Voting satisfies this principle while also having a remarkable ability to avoid tied outcomes in elections even with small numbers of voters. 1 Introduction Voting reform efforts in the United States have achieved significant recent successes in replacing Plurality Voting with Instant Runoff Voting (IRV) for major political elections, including the 2018 San Francisco Mayoral Election and the 2021 New York City Mayoral Election. It is striking, by contrast, that Condorcet voting methods are not currently used in any political elections.1 Condorcet methods use the same ranked ballots as IRV but replace the counting of first-place votes with head- to-head comparisons of candidates: do more voters prefer candidate A to candidate B or prefer B to A? If there is a candidate A who beats every other candidate in such a head-to-head majority comparison, this so-called Condorcet winner wins the election. -
Single-Winner Voting Method Comparison Chart
Single-winner Voting Method Comparison Chart This chart compares the most widely discussed voting methods for electing a single winner (and thus does not deal with multi-seat or proportional representation methods).

A Treasury System for Cryptocurrencies: Enabling Better Collaborative Intelligence ⋆
A Treasury System for Cryptocurrencies: Enabling Better Collaborative Intelligence ? Bingsheng Zhang1, Roman Oliynykov2, and Hamed Balogun3 1 Lancaster University, UK [email protected] 2 Input Output Hong Kong Ltd. [email protected] 3 Lancaster University, UK [email protected] Abstract. A treasury system is a community controlled and decentralized collaborative decision- making mechanism for sustainable funding of the blockchain development and maintenance. During each treasury period, project proposals are submitted, discussed, and voted for; top-ranked projects are funded from the treasury. The Dash governance system is a real-world example of such kind of systems. In this work, we, for the first time, provide a rigorous study of the treasury system. We modelled, designed, and implemented a provably secure treasury system that is compatible with most existing blockchain infrastructures, such as Bitcoin, Ethereum, etc. More specifically, the proposed treasury system supports liquid democracy/delegative voting for better collaborative intelligence. Namely, the stake holders can either vote directly on the proposed projects or delegate their votes to experts. Its core component is a distributed universally composable secure end-to-end verifiable voting protocol. The integrity of the treasury voting decisions is guaranteed even when all the voting committee members are corrupted. To further improve efficiency, we proposed the world's first honest verifier zero-knowledge proof for unit vector encryption with logarithmic size communication. This partial result may be of independent interest to other cryptographic protocols. A pilot system is implemented in Scala over the Scorex 2.0 framework, and its benchmark results indicate that the proposed system can support tens of thousands of treasury participants with high efficiency. -

Foregrounding Female Agency in the Dance Culture of Nigeria
WHAT I DO WHEN I DANCE: FOREGROUNDING FEMALE AGENCY IN THE DANCE CULTURE OF NIGERIA Oladoyin Abiona A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF ARTS August 2021 Committee: Angela Nelson, Advisor Jeremy Wallach Rahdika Gajjala © 2021 Oladoyin Abiona All Rights Reserved iii ABSTRACT Angela Nelson, Advisor Scholarship on female representations in hip hop has been predominantly premised on the sexualization of the female body. By focusing mainly on this singular aspect of the genre, we reduce the whole essence of womanhood in the industry to such interpretations. The limited scope of such discussions deprives the women of opportunities to tell their own stories of what they do when they dance. Seeing the cultural significance of dance as a form of popular culture in the Nigerian context, this essay, from a feminist perspective, closes this gap by engaging in a qualitative exploration of the lives of three female dancers in Nigeria telling their stories through dance. They are Kaffayat Oluwatoyin Shafau (Kaffy), Odumewu Debbie (Debbiepinkie), and Usiwo Orezinena Jane (Janemena). Exploring their social media archives, interviews granted to TV stations and a published autobiography “Alajoota” by Kaffy, this essay contextualizes and complicates the interpretations of sexualization in the Nigerian hip hop dance industry. Through dance Nigerian women performers are able to negotiate the heavily male-dominated hip hop scene. For them, dance is a coping strategy, a profession, a space for redefining self and embracing sexuality and femininity, and a form of youthful identity and inclusion. -
Game Theory and Democracy Homework Problems
Game Theory and Democracy Homework Problems PAGE 82 Challenge Problem: Show that any voting model (such as the Unit Interval Model or the Unit Square Model) which has a point symmetry always has a Condorcet winner for every election, namely the candidate who is closest to the point of symmetry! PAGE 93 Exercise: Show that if there are not any cycles of any length in the preferences of the voters, then there must be a Condorcet winner. (Don’t worry about making your proof rigorous, just convince yourself of this fact, to the point you could clearly explain your ideas to someone else.) PAGE 105 Exercise: Prove that the strongest chain strength of a chain from Candidate Y to Candidate X is 3. (If you can convince a skeptical friend that it is true, then that is a proof.) Exercise: Prove that it is never necessary to use a candidate more than once to find a chain with the strongest chain strength between two candidates. Hint: Show that whenever there is a loop, like the one shown in red Y (7) Z (3) W (9) Y (7) Z (3) W (11) X, we can consider a shortened chain by simply deleting the red loop Y (7) Z (3) W (11) X which is at least as strong as the original loop. Exercises: Prove that all of the chains above are in fact strongest chains, as claimed. Hint: The next figure, which has all of the information of the margin of victory matrix, will be useful, and is the type of figure you may choose to draw for yourself for other elections, from time to time. -

Fifty years in the Northwest http://www.loc.gov/resource/lhbum.01070 Library of Congress At the age of nineteen years, I landed on the banks of the Upper Mississippi, pitching my tent at Prairie du Chien, then (1836) a military post known as Fort Crawford. I kept memoranda of my various changes, and many of the events transpiring. Subsequently, not, however, with any intention of publishing them in book form until 1876, when, reflecting that fifty years spent amidst the early and first white settlements, and continuing till the period of civilization and prosperity, itemized by an observer and participant in the stirring scenes and incidents depicted, might furnish material for an interesting volume, valuable to those who should come after me, I concluded to gather up the items and compile them in a convenient form. -

However, modern implementations of democracy are based on outdated infor- mation technology and must adapt to the changing technological landscape. This thesis explores the relationship between computer science and democracy, which is, crucially, a two-way street—just as principles from computer science can be used to analyze and design democratic paradigms, ideas from democracy can be used to solve hard problems in computer science. Question 1: What can computer science do for democracy? To explore this first question, we examine the theoretical foundations of three democratic paradigms: liquid democracy, participatory budgeting, and multiwinner elections. -
