Generalization, also called anti-unification, is the dual of unification. Given terms t and t′, a generalization is a term t′′ of which t and t′ are substitution instances. The dual of a most general unifier (mgu) is that of least general generalization (lgg). In this work, we extend the known untyped generalization algorithm to an order-sorted typed setting with sorts, subsorts, and subtype po...
