Zusammenfassung
Finite domain constraints are one of the most important constraint domains
in constraint logic programming.
Usually, they are solved by local consistency techniques combined
with enumeration.
We argue that, in many cases, ensuring local consistency is not enough for
both theoretical and practical reasons.
We show how to obtain more information from a given constraint set
by computing cutting planes and how to use this information
in constraint solving and constrained optimization.
Focusing on the pseudo-Boolean case \clppb, where all domains are equal to the
two-element
set $\{0,1\}$, we present specialized cutting plane techniques and illustrate
them on a number of examples.
