This editorial of the special issue “Representing, Processing, and Learning Preferences:
Theoretical and Practical Challenges” surveys past and ongoing research on preferences in …

The study of multi-agent systems (MAS) focuses on systems in which many intelligent agents
interact with each other. These agents are considered to be autonomous entities such as …

After an introductory section, this article will focus on four questions: How should the Kyoto
School be defined? What is meant by its central philosophical concept of “absolute …

There has been a remarkable increase in work at the interface of computer science and
game theory in the past decade. In this article I survey some of the main themes of work in …

Social choice becomes easier on restricted preference domains such as single-peaked,
single-crossing, and Euclidean preferences. Many impossibility theorems disappear, the …

Social choice theory concerns the design and formal analysis of methods for aggregating
the preferences of multiple agents. Examples of such methods include voting procedures …

We study computational aspects of three prominent voting rules that use approval ballots to
elect multiple winners. These rules are satisfaction approval voting, proportional approval …

We study the complexity of influencing elections through bribery: How computationally
complex is it for an external actor to determine whether by paying certain voters to change …

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 …
