k- and t-optimality algorithms [9, 6] provide solutions to
DCOPs that are optimal in regions characterized by its size
and distance respectively. Moreover, they provide quality
guarantees on their solutions. Here we generalise the k- and
t-optimal framework to introduce C-optimality, a
exible framework that provides reward-independent quality guar-
antees for optima in regions characterised by any arbitrary
criterion. Therefore, C-optimality allows us to explore the
space of criteria (beyond size and distance) looking for those
that lead to better solution qualities. We benet from this
larger space of criteria to propose a new criterion, the so-
called size-bounded-distance criterion, which outperforms k-
and t-optimality.
