Split Closure and Intersection Cuts
In the seventies, Balas introduced intersection cuts for a Mixed Integer Linear Program (MILP), and showed that these cuts can be obtained by a closed form formula from a basis of the standard linear programming relaxation. In the early nineties, Cook, Kannan and Schrijver introduced the split closure of an MILP, and showed that the split closure is a polyhedron. In this paper, we show that the...
متن کاملIntersection Algorithms and a Closure Operator on Unordered Trees
Link-based data may be studied formally by means of unordered trees. On a dataset formed by such link-based data, a natural notion of support-based closure can be immediately defined. Abstracting information from subsets of such data requires, first, a formal notion of intersection; second, deeper understanding of the notion of closure; and, third, efficient algorithms for computing intersectio...
متن کاملComparison of Primary Wound Closure with Vacuum Drainage and Delayed Closure in Perforated Appendicitis
Open wound managment after perforated appendicitis has been a common practice but recently, primary closure has been advocated to reduce costs and morbidity. For comparing delayed closures against primary closure with vacuum drainage, a randomized experimental study was designed. in Kerman. Sixty patients with perforated appendicitis divided randomly in two groups and evaluated on day of discha...
متن کاملIntravenous Paracetamol and Patent Ductus Arteriosus Closure
Background: Standard medical treatments for patent ductus arteriosus (PDA) closure are, including indomethacin/ibuprofen and surgical ligation. Nowadays, a new strategy to close PDA is the use of paracetamol. The present study aimed to describe the use of intravenous (IV) paracetamol for PDA closure in neonates who present a contraindication to ibuprofen or ibuprofen failure with no possibility...
