This paper describes the theoretical framework and an implemented system (Dtre) for the speciication and veriied reenement of speciications using operations on abstract data types. The system is semi-automatic in that users can specify some (possibly none) of the implementations and the system will determine the rest of the implementations. Data types are(More)
Planware is a domain-specific generator of high-performance scheduling software, currently being developed at Kestrel Institute. Architecturally, Planware is an extension of the Specware system with domain-independent and domain-dependent parts. The domain-independent part includes a general algorithm design facility (including mechanisms to synthesize(More)
Computer-assisted instruction (CAI) offers many opportunities for the application of artificial intelligence (AI) techniques. One advantage of doing AI research within the CAI paradigm is that the curriculum provides a ready framework for the evaluation of any AI model that we might propose. In this paper we describe the models of informal mathematical(More)
