YapOr is an or-parallel system that extends the Yap Prolog system to exploit implicit or-parallelism in Prolog programs. It is based on the environment copying model, as first imp...
We present three approaches to revision of belief bases, which are also examined in the case in which the sentences in the base are partitioned between those which can and those wh...
We present two models of hierarchical structured multi-agents, and we describe how to obtain a modal knowledge base from distributed sources. We then propose a computationally orie...
OPL is a modeling language for mathematical programming and combinatorial optimization problems. It is the first modeling language to combine high-level algebraic and set notation...

In this paper we propose a hybrid system that bridges the gap between traditional image processing methods, used for low-level object recognition, and abductive constraint logic pr...
We introduce a resource adaptive agent mechanism which supports the user of an interactive theorem proving system. The mechanism, an extension of 5 , uses a two layered architectur...
