Defeasible Logic is extended to programming languages for cognitive agents with preferences and actions for planning. We define rule-based agent theories that contain preferences ...
In reasoning tasks involving logical formulas, high expressiveness is desirable, although it often leads to high computational complexity. We study a simple measure of expressiven...
Real-Time Logic is a formal notation for reasoning about temporal behaviour. Z is a general purpose specification language, but lacks explicit features for expressing real-time co...
We sketch a methodology for the verification of compiler correctness based on the LF Logical Framework as realized within the Elf programming language. We have applied this techni...
Abstract. We present a lightweight, automated tool for specificationbased testing of declarative programs written in the functional logic programming language Curry and emphasize t...
