Visualization can facilitate the understanding of the structures of a collection of documents that are related to each other by links, such as citations in formal publications. We...
We introduce a geometric process algebra based on affine geometry, with the aim of describing the concurrent evolution of geometric structures in 3D space. We prove a relativity th...
We prove that TAUT has a p-optimal proof system if and only if a logic related to least fixed-point logic captures polynomial time on all finite structures. Furthermore, we show ...
We present compelling evidence that the World Wide Web is a domain in which applications can benefit from using first-order learning methods, since the graph structure inherent in ...
A number of algorithms are available for computing the simulation relation on Kripke structures and on labelled transition systems representing concurrent systems. Among them, the...
