چکیده

The solution of convex Mixed Integer Quadratic Programming (MIQP) problems with a general branch{and{bound framework is considered. It is shown how lower bounds can be computed eeciently during the branch{and{bound process. Improved lower bounds such as the ones derived in this paper can reduce the number of QP problems that have to be solved. The branch{and{bound approach is also shown to be superior to other approaches to solving MIQP problems. Numerical experience is presented which supports these conclusions.

Solving Mixed-Integer Quadratic Programs Via Nonnegative Least Squares

Abstract: This paper proposes a new algorithm for solving Mixed-Integer Quadratic Programming (MIQP) problems. The algorithm is particularly tailored to solving small-scale MIQPs such as those that arise in embedded hybrid Model Predictive Control (MPC) applications. The approach combines branch and bound (B&B) with nonnegative least squares (NNLS), that are used to solve Quadratic Programming ...

Integer Quadratic Programming for Control and Communication

The main topic of this thesis is integer quadratic programming with applications to prob-lems arising in the areas of automatic control and communication. One of the mostwidespread modern control methods is Model Predictive Control (MPC). In each sam-pling time, MPC requires the solution of a Quadratic Programming (QP) problem. Tobe able to use MPC for large systems, and at high...

A Bound Strengthening Method for Optimal Transmission Switching in Power Systems

This paper studies the optimal transmission switching (OTS) problem for power systems, where certain lines are fixed (uncontrollable) and the remaining ones are controllable via on/off switches. The goal is to identify a topology of the power grid that minimizes the cost of the system operation while satisfying the physical and operational constraints. Most of the existing methods for the probl...

Bounds for Multiple-Access Relay Channels with Feedback via Two-way Relay Channel

In this study, we introduce a new two-way relay channel and obtain an inner bound and an outer bound for the discrete and memoryless multiple access relay channels with receiver-source feedback via two-way relay channel in which end nodes exchange signals by a relay node. And we extend these results to the Gaussian case. By numerical computing, we show that our inner bound is the same with o...
