Generalized rules in incomplete information systems

Marzena Kryszkiewicz

Abstract

In the paper we define a notion of a generalized decision rule in a system with incomplete information. A generalized rule may be indefinite. A definite generalized rule is called certain. A rule is defined as generalized in an incomplete system if it is generalized in every completion of the incomplete system. Careful examination of the dependencies between an incomplete system and its completions allow us to state that all optimal generalized rules can be generated from the initial incomplete system. We show how to compute such rules by means of Boolean reasoning.
