Abstract

The complexity of the general inference problem for propositional circumscription in Boolean logic (or equivalently over the two-element domain) has been recently classified. This paper generalizes the problem to arbitrary finite domains. The problem we study here is parameterized by a set of relations (a constraint language), from which we are allowed to build a knowledge base, and a linear order on the domain, which is used to compare models.
We use the algebraic approach provided originally in order to understand the complexity of the constraint satisfaction problem to give first non-trivial dichotomies and tractability results for the minimal inference problem over finite domains.

Fußnoten
1
Recently, three different groups of researchers announced a proof of the dichotomy.
 
2
The paper claims that the dichotomy is for all languages over the three-element domain. However, this is not true since the proof of Theorem 3.6 is flawed for domains with more than two elements [14].
