Cutting Plane Algorithms are Exact for Euclidean Max-Sum Problems
Hoa T. Bui, Sandy Spiers, Ryan Loxton
This paper studies binary quadratic programs in which the objective is defined by a Euclidean distance matrix, subject to a general polyhedral constraint set. This class of nonconc…
An exact cutting plane method for solving p-dispersion-sum problems
Sandy Spiers, Hoa T. Bui, Ryan Loxton
This paper aims to answer an open question recently posed in the literature, that is to find a fast exact method for solving the p-dispersion-sum problem (PDSP), a nonconcave quadr…
Cutting plane algorithms for nonlinear binary optimization
Hoa T. Bui, Qun Lin, Ryan Loxton
Current state-of-the-art methods for solving discrete optimization problems are usually restricted to convex settings. In this paper, we propose a general approach based on cutting…
A Note on the Finite Convergence of Alternating Projections
Hoa T. Bui, Ryan Loxton, Asghar Moeini
We establish sufficient conditions for finite convergence of the alternating projections method for two non-intersecting and potentially nonconvex sets. Our results are based on a…
Dynamic Optimization of Trajectory for Ramp-up Current Profile in Tokamak Plasmas
Zhigang Ren, Chao Xu, Yongsheng Ou
In this paper, we consider an open-loop, finite-time, optimal control problem of attaining a specific desired current profile during the ramp-up phase by finding the best open-loop…
A Gradient-based Kernel Optimization Approach for Parabolic Distributed Parameter Control Systems
Zhigang Ren, Chao Xu, Qun Lin +1
This paper proposes a new gradient-based optimization approach for designing optimal feedback kernels for parabolic distributed parameter systems with boundary control. Unlike trad…
Optimal Boundary Control for Water Hammer Suppression in Fluid Transmission Pipelines
Tehuan Chen, Chao Xu, Zhigang Ren +1
When fluid flow in a pipeline is suddenly halted, a pressure surge or wave is created within the pipeline. This phenomenon, called water hammer, can cause major damage to pipelines…
Bi-objective Optimization for Robust RGB-D Visual Odometry
Tao Han, Chao Xu, Ryan Loxton +1
This paper considers a new bi-objective optimization formulation for robust RGB-D visual odometry. We investigate two methods for solving the proposed bi-objective optimization pro…
