Abstract:We consider bi-criteria optimization problems for decision rules and rule systems relative to length and coverage. We study decision tables with many-valued decisions in which each row is associated with a set of decisions as well as single-valued decisions where each row has a single decision. Short rules are more understandable; rules covering more rows are more general. Both of these problems -minimization of length and maximization of coverage of rules are NP-hard. We create dynamic programming algorithms … Show more
