Belief Revision via PS-Merge under constraints belief merging operator
Belief revision is a central topic in knowledge representation and reasoning. It consists in incorporating a new belief, changing as few as
possible of the original beliefs while preserving consistency.
Revision always considers new evidence as a better belief. Such new evidence is usually
represented in the form of a propositional formula which must be preserved after the
revision.
Here, the Δps (PS-Merge) belief merging operator is extended in order to consider constraints, and ...
Semantic query optimization (SQO) is the process of finding equivalent rewritings of an input query given constraints that hold in a database instance. We present a Chase & Backchase (C&B) algorithm strategy that generalizes and improves on well-known methods in the field. The implementation of our approach, the pegasus system, outperforms existing C&B systems an average by two orders of magnitude. This gain in performance is due to a combination of novel methods that lower the complexity...
A platform which hosts battles between Fruit War robots - special java programs. The platform accepts source code as robot, and ranks all robots according to battle result. This project has been totally refined and is now hosted at http://robotypo.appspot.com
The project is about turn-based, networked multiplayer, non-cooperative, zero-sum, abstract strategy board games (e.g. Chess, Go, Reversi variants, etc.) on 3D-visualized polyhedra and related recreational (discrete, computational) mathematics.
