In this paper, we study the complexity of model-checking formulas of three important real-time logics (MTL, MITL, and TCTL) over restricted sets of timed paths. The classes of rest...
A vector algorithm is an algorithm that applies a bounded number of vector operations to an input vector, regardless of the length of the input. In this paper, we describe the link...
In this paper, an algorithm for obtaining consistent answers to queries posed to inconsistent relational databases is presented. The algorith is proven to be sound, terminating and...
Abstract. An object-oriented language that permits changing the behavior of a class or of a single object is said to support computational reflection. Existing reflective facilitie...
We prove old and new results on the complexity of computing the dimension of algebraic varieties. In particular, we show that this problem is NP-complete in the Blum-Shub-Smale mo...
