Focus+context visualization techniques aim to give users integrated visual access to both details and overview of a data set. This paper gives a systematic account of such visuali...
Abstract. Existing constraint programming systems offer a fixed set of inference engines implementing search strategies such as single, all, and best solution search. This is unfo...
Abstract. We propose a theory of up-to techniques for proofs by coinduction, in the setting of complete lattices. This theory improves over existing results by providing a way to c...
Abstract. Model verification examines the correctness of a model implementation with respect to a model specification. While being described from model specification, implementatio...
Abstract. Service oriented computing oers a new approach to programming. To be useful for large and diverse sets of problems, eective service selection and composition is crucial. ...
