We discuss two approximation approaches, the primal-dual schema and the local-ratio technique. We present two relatively simple frameworks, one for each approach, which extend know...
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...
We study the Maximum Flow Network Interdiction Problem (MFNIP). We present two classes of polynomially separable valid inequalities for Cardinality MFNIP. We also prove the integr...
Abstract. Nested if-then-else statements is the most common programming schema in applications like data transformation or data analysis. In most cases, these can be replaced by hi...
Agile methodologies can be enhanced by the use of shadows as this feature because of its inherent ability to dynamically change the behavior of classes and objects, provides mecha...
