Abstract. The process through which disordered components spontaneously arrange themselves into patterns is called self-assembly. Molecular self-assembly describes the process by w...
Abstract. We consider the problem of query containment for conjunctive queries with safe negation property. A necessary and sufficient condition for two queries to be in containmen...
Modernlarge real-time systems are becoming more complex. Whilst Ada 2005 provides a comprehensive set of programming mechanisms that allow these systems to be implethe abstraction...
Abstract. We study the problem of determining the complexity of optimal comparison-based in-place sorting when the key length, k, is not a constant. We present the first algorithm...
Abstract. We outline a general theory of graph polynomials which covers all the examples we found in the vast literature, in particular, the chromatic polynomial, various generaliz...
