Abstract. Over the past years, a number of increasingly expressive languages for modelling constraint and optimisation problems have evolved. In developing a strategy to ease the c...
We use computational systems to express a completion with constraints procedure that gives priority to simpliļ¬cations. Computational systems are rewrite theories enriched by stra...
We address the learning of trust based on past observations and context information. We argue that from the truster's point of view trust is best expressed as one of several ...
