AbstractA choice function is (weakly) width-maximizing if there exists a dissimilarity- i.e. an irreflexive symmetric binary relation- on the underlying object set such that the choice sets are (include, respectively) dissimilarity chains of locally maximum size. Width-maximizing and weakly width-maximizing choice functions on an arbitrary domain are characterized relying on the newly introduced notion of a revealed dissimilarity relation.
