Multi-Objective Optimization Strategy of Integrated Electric-Heat System Based on Energy Storage Situation Division

open access: yesIEEE Access, 2021
There are the transmission loss of the electric power network, the delay and loss of the heating network, the insufficient utilization of flexible resources such as energy storage in the integrated electric-heat system, which may lead to the imbalance of

Full-Duplex Amplify-and-Forward MIMO Relaying: Design and Performance Analysis Under Erroneous CSI and Hardware Impairments

open access: yesIEEE Open Journal of the Communications Society, 2021
Full-duplex amplify-and-forward multiple-input multiple-output relaying has been the focus of several recent studies, due to the potential for achieving a higher spectral efficiency and lower latency, together with inherent processing simplicity. However,

Quadratically adjustable robust linear optimization with inexact data via generalized S-lemma: Exact second-order cone program reformulations

open access: yesEURO Journal on Computational Optimization, 2021
Adjustable robust optimization allows for some variables to depend upon the uncertain data after its realization. However, the uncertainty is often not revealed exactly.

Lifted Convex Quadratic Programming

open access: yesCoRR, 2016
Symmetry is the essential element of lifted inference that has recently demon- strated the possibility to perform very efficient inference in highly-connected, but symmetric probabilistic models models. This raises the question, whether this holds for optimisation problems in general.

On convex relaxations for quadratically constrained quadratic programming [PDF]

open access: yesMathematical Programming, 2012
A quadratically constrained (possibly non-convex) quadratic programming problem is considered. The efficiency, for this problem, of several known convex underestimating methods is analyzed. The underestimates, obtained by means of the considered methods, are ranked according to their tightness.

An Accelerated Proximal Gradient Algorithm for Singly Linearly Constrained Quadratic Programs with Box Constraints

open access: yesThe Scientific World Journal, 2013
Recently, the existed proximal gradient algorithms had been used to solve non-smooth convex optimization problems. As a special nonsmooth convex problem, the singly linearly constrained quadratic programs with box constraints appear in a wide range of ...

On the minimum-norm solution of convex quadratic programming [PDF]

open access: yesRAIRO - Operations Research, 2021
We discuss some basic concepts and present a numerical procedure for finding the minimum-norm solution of convex quadratic programs (QPs) subject to linear equality and inequality constraints. Our approach is based on a theorem of alternatives and on a convenient characterization of the solution set of convex QPs.

An efficient beamforming design for multipair full-duplex relaying systems

open access: yesICT Express, 2017
We consider a decode-and-forward full-duplex relaying system for multiple pairs of users. Our objective is to maximize the minimum achievable rate for all user pairs under the transmit power constraints.
