Abstract. We review key constraints in the context of XML as introduced by Buneman et al. We show that one of the proposed inference rules is not sound in general, and the axiomati...
Automated control of a virtual camera is useful for both linear animation and interactive virtual environments. We have constructed a knowledge-based system that allows users to e...
We address the problem of verifying planning domains as used in model-based planning, for example in space missions. We propose a methodology for testing flight rules of planning...
This paper shows that program algebra (PGA) [8] offers a mathematical and systematic framework for reasoning about correctness and equivalence of algorithms and transformation rul...
Based on inductive definitions, we develop a tool that automates the definition of partial recursive functions in higher-order logic (HOL) and provides appropriate proof rules for ...
