In this paper we define the notion of a compatibility relation so as to have a common framework for three nonmonotonic reasoning systems: normal logic programming, extended logic ...
Because of irreversibility of movements, motion planning on directed graphs is much more intricate than that on graphs. Recently we showed that the feasibility of motion planning o...
The Conceptual Programming environment, CP, being developed at the Computing Research Laboratory (CRL), is a complete knowledge representation visual programming environment for u...
In the field of structural pattern recognition graphs constitute a very common and powerful way of representing patterns. In contrast to string representations, graphs allow us to ...
An object-oriented approach to program specification and verification was developed by Ole-Johan Dahl with the long-term Abel project. Essential here was the idea of reasoning abou...
