One of the most actively growing subareas in multi-agent systems is computational social choice theory, which provides a theoretical foundation for preference aggregation and collective decision-making in multi-agent domains. It is concerned with the application of techniques developed in computer science, including complexity analysis and algorithm design, in the study of social choice mechanisms, such as voting. It seeks to import concepts from social choice theory into Artificial Intelligence and computing. People often have to reach a joint decision despite conflicting preferences over the alternatives. This joint decision can be reached by an informal negotiating process or by a carefully specified protocol. Over the course of the past decade or so, computer scientists have also become deeply involved in this study. Within computer science, there is a number of settings where a decision must be made based on the conflicting preferences of multiple parties. The paradigms of computer science give a different and useful perspective on some of the classic problems in economics and related disciplines. A natural and very general approach for deciding among multiple alternatives is to vote on them. Voting is one of the most popular ways of reaching common decisions. As such, the study of elections is an area where fields such as computer science, economics, business, operations research, and political science can be brought together. Social choice theory deals with voting scenarios, in which a set of individuals must select an outcome from a set of alternatives. This book focuses on convergence to pure strategy Nash equilibria in plurality voting games and a number of other positional and non-positional scoring rules. In such games, the voters strategically choose a candidate to vote for, and the winner is determined by the plurality (or other) voting rules. Voters take turns modifying their votes; these manipulations are classified according to the way in which they affect the outcome of the election. The focus is on achieving a stable outcome, taking strategic behaviour into account. A voting profile is in equilibrium, when no voter can change his vote so that his more preferable candidate gets elected. The book investigates restrictions on the number of iterations that can be made for different voting rules, considering both weighted and equi-weighted voting settings.

Explore the complex world of runoff voting and its strategic implications in this insightful guide. Aimed at professionals, students, and enthusiasts, this book unveils the subtle tactics that can dramatically shape election outcomes. 1: Tactical Manipulation of Runoff Voting: Grasp how tactical manipulation can shift electoral results, shaping the outcome. 2: Strategic Voting: Understand how voters may cast votes not solely by preference but for favorable outcomes. 3: Independence of Irrelevant Alternatives: Explore how election results are affected by non-winning candidates. 4: Vote Pairing: Learn how voters agree to swap votes to achieve mutually beneficial results. 5: Vote Splitting: Analyze how multiple similar candidates can split votes, affecting results. 6: 2002 French Presidential Election: A case study illustrating tactical voting in the 2002 French presidential election. 7: Coombs' Method: Explore an elimination-based voting system that removes the least popular candidates. 8: Exhaustive Ballot: Understand how this system works by eliminating candidates one by one. 9: Contingent Vote: Explore a hybrid system combining elements of plurality and instant-runoff voting. 10: Instant-Runoff Voting: Learn the mechanics of ranking candidates and how votes transfer in rounds. 11: Approval Voting: Discover a system where voters can approve multiple candidates at once. 12: Plurality Voting: Examine the plurality system, where the most votes win, despite possible manipulation. 13: Two-Round System: Learn about this system, which calls for a second voting round if no majority is achieved. 14: Bullet Voting: Understand the practice of voting for only one candidate despite having more options. 15: 2002 French Legislative Election: Analyze another case study of tactical voting in French legislative elections. 16: Supplementary Vote: Learn about this variation of instant-runoff voting in elections. 17: Plural Left: Study the coalition within the Plural Left and its electoral influence. 18: Borda Count: Explore a ranking system where points are assigned based on candidates' positions. 19: Schulze STV: Learn about this method, which aims to minimize wasted votes. 20: 2016 The Republicans Presidential Primary: A case study on strategic voting in the 2016 French Republican primary. 21: STAR Voting: Understand the STAR voting system, combining scoring and runoff methods. Through this exploration, you’ll unlock the hidden strategies used in elections and gain the tools to analyze or participate in political systems with greater expertise. With in-depth insights into voting systems from around the globe, you’ll be well-equipped to navigate and influence electoral outcomes more strategically. Whether you're involved in political campaigns or academic research, this guide offers a transformative understanding of runoff voting tactics.
