Semidefinite approximation for mixed binary quadratically constrained quadratic programs [PDF]
, 2014 Motivated by applications in wireless communications, this paper develops semidefinite programming (SDP) relaxation techniques for some mixed binary quadratically constrained quadratic programs (MBQCQP) and analyzes their approximation performance.

International Journal of Robust and Nonlinear Control, Volume 35, Issue 6, Page 2142-2155, April 2025.ABSTRACT Steering a nonlinear system from an initial state to a desired one is a common task in control. While a nominal trajectory can be obtained rather systematically using a model, for example, via numerical optimization, heuristics, or reinforcement learning, the design of a computationally fast and reliable feedback control law that guarantees ...

A Convex Optimization Approach to Compute Trapping Regions for Lossless Quadratic Systems
International Journal of Robust and Nonlinear Control, Volume 35, Issue 6, Page 2425-2436, April 2025.ABSTRACT Quadratic systems with lossless quadratic terms arise in many applications, including models of atmosphere and incompressible fluid flows. Such systems have a trapping region if all trajectories eventually converge to and stay within a bounded set.

Optimal Control for a Class of Chaotic Systems
Journal of Applied Mathematics, 2012 This paper proposes the optimal control methods for a class of chaotic systems via state feedback. By converting the chaotic systems to the form of uncertain piecewise linear systems, we can obtain the optimal controller minimizing the upper bound on ...

IET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.This paper presents a novel solution for a constrained H∞$H_\infty$ optimal tracking control problem for LTI systems with unknown models. The proposed approach consists of two novel algorithms including an input constraint model‐based algorithm, and a data‐based algorithm for systems with completely unknown models.

Layout Decomposition for Quadruple Patterning Lithography and Beyond
, 2014 For next-generation technology nodes, multiple patterning lithography (MPL) has emerged as a key solution, e.g., triple patterning lithography (TPL) for 14/11nm, and quadruple patterning lithography (QPL) for sub-10nm. In this paper, we propose a generic

Energy efficiency maximization in IRS‐aided cooperative WPCN with non‐linear EH users
Electronics Letters, Volume 61, Issue 1, January/December 2025.The paper investigates energy efficiency maximization in intelligent reflecting surfaces aided wireless‐powered communication network with hybrid access point and non‐linear energy harvesting users. The focus is on maximizing energy efficiency at the hybrid access point by jointly optimizing transmit time allocation, power allocation at users, and ...

Bounding Option Prices Using SDP With Change Of Numeraire [PDF]
Recently, given the first few moments, tight upper and lower bounds of the no arbitrage prices can be obtained by solving semidefinite programming (SDP) or linear programming (LP) problems.

Exact Solution Methods for the $k$-item Quadratic Knapsack Problem
, 2016 The purpose of this paper is to solve the 0-1 $k$-item quadratic knapsack problem $(kQKP)$, a problem of maximizing a quadratic function subject to two linear constraints. We propose an exact method based on semidefinite optimization.
