The binary relation framework has been shown to be applicable to many real-life preference handling scenarios. Here we study preference contraction: the problem of discarding selected preferences.

Contractions can be further constrained by specifying which preferences should be protected. We consider preference relations that are finite or finitely representable using preference… CONTINUE READING
