Individuals do not typically reason in isolation when confronted with collectivedecision
making, but rather take into consideration the preferences of likeminded individuals and …

We investigate the effect a social network could have on voting outcomes. We consider a
group of self-interested agents where each agent has a strict preference order over a set of …

Social networks play a central role in individual interactions and decision making. While it is
recognized that networks can correlate behaviors and preferences among connected …

In this paper we present a two-fold generalization of conditional preference networks (CP-
nets) that incorporates uncertainty. CP-nets are a formal tool to model qualitative conditional …

We study the complexity of Destructive Shift Bribery. In this problem, we are given an
election with a set of candidates and a set of voters (each ranking the candidates from the …

We introduce PCP-nets, a formalism to model qualitative conditional preferences with
probabilistic uncertainty. PCP-nets generalise CP-nets by allowing for uncertainty over the …

ABSTRACT PCP-nets generalize CP-nets to model conditional preferences with
probabilistic uncertainty. In this paper we use PCP-nets in a multiagent context to compactly …

How do humans or machines make a decision? Whenever we make a decision, we consider
our preferences over the possible options. Also, in a social context, collective decisions are …

Aggregating preferences over combinatorial domains has many applications in artificial
intelligence (AI). Given the inherent exponential nature of preferences over combinatorial …

We investigate the effects that social influence can have on the behaviour of agents in a
social network in the context of an election. In particular, we study how the structure of a …
