CP-Nets have proven to be an effective representation for capturing preferences. However, their use in multiagent negotiation is not straightforward. The main reason for this is that CP-Nets capture partial ordering of preferences, whereas negotiating agents are required to compare any two outcomes based on the request and offers. This makes it necessary for agents to generate total orders from...

This paper is a survey of some of the ways in which the representation theory of the symmetric group has been used in voting theory and game theory. In particular, we use permutation representations that arise from the action of the symmetric group on tabloids to describe, for example, a surprising relationship between the Borda count and Kemeny rule in voting. We also explain a powerful repres...

We consider best-reply dynamics for voting games in which all players are strategic and no coalitions are formed. We study the class of scoring rules, show convergence of a suitably restricted version for the plurality and veto rules, and failure of convergence for other rules including k-approval and Borda. In particular, for 3 candidates convergence fails for all rules other than plurality an...

This paper presents an application of voting geometry to individual decision making. We demonstrate that a number of decision anomalies can arise as a natural consequence of the aggregation of preferences of different neural systems. We present a proof of existence of a set of voting procedures that can account for the attraction effect, the similarity effect and the compromise effect, and prov...

We visualize aggregate outputs of popular multiwinner voting rules—SNTV, STV, Bloc, k-Borda, Monroe, Chamberlin– Courant, and PAV—for elections generated according to the two-dimensional Euclidean model. We consider three applications of multiwinner voting, namely, parliamentary elections, portfolio/movie selection, and shortlisting, and use our results to understand which of our rules seem to ...

Here we investigate how strategic adaptation changes our understanding and predictions of voting systems. We model populations of agents voting in multiple elections over time that revise their voting strategies based on electoral outcomes. Using this framework we examine the dynamic formation of electoral outcomes. Allowing agents to adapt their strategies refines the predictions of rational c...

Discussion papers are research materials circulated by their authors for purposes of information and discussion. They have not necessarily undergone formal peer review or editorial treatment. Summary This paper is about measuring social well-being and evaluating policy. Section 1 concerns the links between the two, while Sections 2 and 3, respectively, are devoted to the development of appropri...

The Vision Research Lab at the University of California at Santa Barbara participated in three TRECVID 2007 tasks: rushes summarization, high level feature extraction, and search. This paper describes contributions in the high level feature and search tasks. The high level feature submissions relied on visual features for three runs, audio features exclusively for one, and a fusion of audio and...
