Abstract: Underspecification is a good way to deal with partial functions in specification and reasoning. However, when underspecification is used, implementations may unintentionally be forced to depend on parts of the specification that were supposed to be underspecified. We show how to write pre- and postcondition specifications that avoid such problems, by having the precondition "protect" the postcondition from the effects of underspecification. This approach is most practical if the specification... (Update)
