Abstract. We present a well-founded semantics for deductive objectoriented database (dood) languages by applying the alternating- xpoint characterization of the well-founded model ...
Input validation refers to checking user inputs to a program to ensure that they conform to expectations of the program. Input validation is used to check the format of numbers and...
Abstract. We examine to what extent implementation of timed automata can be achieved using the standard semantics and appropriate modeling, instead of introducing new semantics. We...
Abstract. We study the complexity of consistency checking and query answering on incomplete databases for languages ranging from non-recursive Datalog to disjunctive Datalog with n...
Since Findler and Felleisen [2002] introduced higher-order contracts, many variants have been proposed. Broadly, these fall into two groups: some follow Findler and Felleisen in u...
