Abstract

Conditional importance networks (CI-nets) provide a formal framework for modeling and reasoning with qualitative preferences over sets of many variables. Existing approaches for verifying the satisfiability of a CI-net operate on a complete model of the CI-net’s semantics, but the time required to construct this model limits the practical usefulness of CI-nets. We present an algorithm that decides a CI-net’s satisfiability by analyzing a sufficient partial model of its semantics, and we show how to efficiently construct such a model. Our method significantly reduces the average time needed to verify the satisfiability of CI-nets.
