Optimality, Belief and Preference
Dick de Jongh, Fenrong Liu

Abstract:
We define preference in terms of a constraint sequence, a concept from
optimality theory. In case agents only have incomplete information,
beliefs are introduced. We propose three definitions to describe
dierent procedures agents may follow to get a preference relation
using the incomplete information. Changes of preference are explored
w.r.t their sources: changes of the constraint sequence, and changes
in beliefs.
