Abstract

In a multi-agent context where a set of agents declares their preferences over a common set of candidates, it is often the case that agents may influence each others. Recent work has modelled the influence phenomenon in the case of voting over a single issue. Here we generalize this model to account for preferences over combinatorially structured domains including several issues. When agents express their preferences as CP-nets, we show how to model influence functions and how to aggregate preferences by interleaving voting and influence convergence.
