Abstract. In this paper, we present a major improvement in the search procedures in constraint programming. First, we integrate various search procedures from AI and OR. Second, we...
We present a purely functional implementation of the computational differentiation tools — the well known numeric (i.e., not symbolic) techniques which permit one to compute poin...
We study the complexity of the problem of answering queries using materialized views. This problem has attracted a lot of attention recently because of its relevance in data integ...
Investigating soundness and completeness of verification calculi for imperative programming languages is a challenging task. Incorrect results have been published in the past. We t...
We describe how to express homomorphic translations with an object-oriented design. This includes a uniform approach to the addition of external functionality to data structures. ...
