Computational social choice is an interdisciplinary field of study at the interface of social
choice theory and computer science, promoting an exchange of ideas in both directions. On …

Voting is a general method for aggregating the preferences of multiple agents. Each agent
ranks all the possible alternatives, and based on this, an aggregate ranking of the …

We propose methods for an AI agent to estimate the value preferences of individuals in a
hybrid participatory system, considering a setting where participants make choices and …

Preferences are not always expressible via complete linear orders: sometimes it is more
natural to allow for the presence of incomparable outcomes. This may hold both in the …

A (randomized, anonymous) voting rule maps any multiset of total orders (aka. votes) over a
fixed set of alternatives to a probability distribution over these alternatives. A voting rule f is …

Understanding citizens' values in participatory systems is crucial for citizen-centric policy-
making. We envision a hybrid participatory system where participants make choices and …

Belief merging is often described as the process of defining a base which best represents
the beliefs of a group of agents (a profile of belief bases). The resulting base can be viewed …

Modelling the preferences of a decision maker about alternatives having multiple criteria
usually starts by collecting preference information (comparisons of alternatives, importance …

In a preference aggregation setting, a group of agents must jointly make a decision, based
on the individual agents' privately known preferences. To do so, the agents need some …

This paper deals with preference representation and aggregation in the context of
multiattribute utility theory. We consider a set of alternatives having a combinatorial structure …
