We present a constructive approach to correctness and exemplify it by describing a generator for certified Java Card applets that we are building. A proof of full functional correctness is generated, along with the code, from the specification; the proof can be independently checked by a simple proof checker, so that the larger and more complex generator(More)
Over the last few years, technologies for the formal description, construction, analysis, and validation of software - based mostly on logics and formal reasoning - have matured. We can expect them to complement and partly replace traditional software engineering methods in the future. Formal methods in software engineering are an increasingly important(More)
NASA is using model-based languages and risk analysis methodologies to raise software development to the level of hardware development. Ultimately, it hopes to achieve a fusion of systems and software engineering by replacing conventional software development techniques with capability engineering, which focuses on a system's full set of functionalities.
Executive Summary In August 1998 the President's Information Technology Advisory Committee (PITAC) submitted an Interim Report emphasizing the importance of sottw~se l:o the nation and calling for a significant new federal investment in software researck ~ An NSF workshop subsequently brought together representatives of a broad segment of the software(More)
This paper shows how an extension of the resolution proof procedure can be used to construct problem solutions. The extended proof procedure can solve problems involving state transformations. The paper explores several al ternate problem representations and provides a discussion of solutions to sample problems including the "Monkey and Bananas " puzzle and(More)
In the effort to construct intelligent computer systems, a primary consideration is how to represent large amounts of knowledge in a fashion that permits their effective use and interaction. Indeed, many researchers in the field of artificial intelligence have come to believe that knowledge representation is the fundamental issue in the attempt to(More)
The 1983 KBSA (Knowledge-Based Software Assistant) report led to the founding of the KBSE (Knowledge-Based Software Engineering conference series. The KBSE conference then changed into the ASE conference in 1997. And this year marks the 25th anniversary of the conference series. As an author of the KBSA report I was invited to talk here about the report(More)
This session focuses on the continuing effort to develop automatic techniques for transforming a specification of “what” is to be done into a specification of “how” the “what” is to be done. One presentation deals with programming tasks, where the results of the transformation are executable computer programs. The other(More)
