Exact top-k query processing has caught much attention recently because of its wide use in many research areas. Since missing the truly best answers is inherent and unavoidable due to the user’s subjective judgment, and the cost of processing exact top-k queries is highly expensive for datasets with huge volume, it is intriguing to answer approximate top-k query instead. In this paper, we defin...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
