Query Languages for Real Number Databases Based on Descriptive Complexity over Rour approach is based on real number complexity theory as introduced in [.] and descriptive complexity for the latter developed in [.]. Using this formal framework a uniform treatment of query languages for such databases is obtained. Precise results about both the data- and the expression-complexit

Efficiency of Fast Parallel Pattern Searching in Highly Compressed Textstially large with respect to its compressed version, and . means .. Given an uncompressed pattern . and a compressed version of a text ., the . problem is to test if . occurs in .. Two types of closely related compressed representations of 1-dimensional texts are considered: the Lempel-Ziv encodings

Computing and Comparing Semantics of Programs in Four-Valued Logicsnot be inferred from the rules. Thus, the well founded semantics corresponds to the assumption that every such atom is false, while the Kripke-Kleene semantics corresponds to the assumption that every such atom is unknown. In this paper, we propose to unify and extend this assumption-based approach

Message Sequence Graphs and Decision Problems on Mazurkiewicz Tracesision problems concerning the correctness and the consistency of a design based by MSC graphs. Both problems are shown to be undecidable, in general. Using a natural connectivity assumption from Mazurkiewicz trace theory we show both problems to be EXPSPACE-complete for locally synchronized graphs.

On the Complexity of Recognizing the Hilbert Basis of a Linear Diophantine Systemeger programming. In automated deduction, the Hilbert basis of a corresponding system serves to compute the minimal complete set of associative-commutative unifiers, whereas in integer programming the Hilbert bases are tightly connected to integer polyhedra and to the notion of total dual integralit
