Patent US 9,715,664

A technique for detecting missing rules (mr) with most general conditions in a rule project (1) having a given scope with a fixed number of objects of a given type, wherein each rule (r) is defined by at least one test (t) in respect to at least one condition of at least one attribute (age, value) of the object, the method comprising the steps of finding at least one missing case not covered by the rules (r), identifying a list of tests (t) that occur in the rules (r), generalizing the missing case into a family of missing cases (mc) in terms of the tests (t) occurring in the rules (r), generalizing the family of missing cases (mc) into a missing rule (mr), and generating missing rules (mr) with most general conditions.
