چکیده

We introduce a concept that generalizes several different notions of a “centerpoint” in the literature. We develop an oracle-based algorithm for convex mixed-integer optimization based on centerpoints. Further, we show that algorithms based on centerpoints are “best possible” in a certain sense. Motivated by this, we establish structural results about this concept and provide efficient algorithms for computing these points. Our main motivation is to understand the complexity of oracle-based convex mixed-integer optimization.

k-Centerpoints Conjectures for Pointsets in ℝd

In this paper, we introduce the notion of k-centerpoints for any set P of n points in Rd. These unify and generalize previous results such as the classical centerpoint theorem 1, and the recently-proven ray-shooting theorem 2. We define two variants: affine k-centerpoints, and topological k-centerpoints. We prove their equivalence in R2, and conjecture that these are in fact equivalent in any d...

Optimum Shape Design of a Radiant Oven by the Conjugate Gradient Method and a Grid Regularization Approach

This study presents an optimization problem for shape design of a 2-D radiant enclosure with transparent medium and gray-diffuse surfaces. The aim of the design problem is to find the optimum geometry of a radiant enclosure from the knowledge of temperature and heat flux over some parts of boundary surface, namely the design surface. The solution of radiative heat transfer is based on the net r...

Optimization of die geometry for tube channel pressing

Since tubes have numerous industrial applications, different attempts are focused on the severe plastic deformation processes of tubes. As an illustration, tube channel pressing (TCP) is an attractive process for this purpose since it can be used for processing of different sizes of tubes. However, more attempts are needed to improve the outcomes of TCP. For example, imposing of a greater strai...

Joint Allocation of Computational and Communication Resources to Improve Energy Efficiency in Cellular Networks

Mobile cloud computing (MCC) is a new technology that has been developed to overcome the restrictions of smart mobile devices (e.g. battery, processing power, storage capacity, etc.) to send a part of the program (with complex computing) to the cloud server (CS). In this paper, we study a multi-cell with multi-input and multi-output (MIMO) system in which the cell-interior users request service...
