We consider unranked trees, that have become an active subject of study recently due to XML applications, and characterize commonly used fragments of firstorder (FO) and monadic ...
Ultraprecision turning is a manufacturing process used to generate a high surface roughness in precision components, and its input-output relationships are highly nonlinear. Surfa...
Abstract. In the paper we present a purely logical approach to estimating computational complexity of potentially intractable problems. The approach is based on descriptive complex...
We introduce choice logic programs as negation-free datalog programs that allow rules to have exclusive-only (possibly empty) disjunctions in the head. Such programs naturally mod...
Code-based metrics such as coupling and cohesion are used to measure a system's structural complexity. But dealing with large systems--those consisting of several millions of...
