ON OPTIMUM DESIGN OF FRAME STRUCTURES

open access: yesActa Polytechnica CTU Proceedings, 2020
Optimization of frame structures is formulated as a non-convex optimization problem, which is currently solved to local optimality. In this contribution, we investigate four optimization approaches: (i) general non-linear optimization, (ii) optimality ...

On the Embed and Project Algorithm for the Graph Bandwidth Problem

open access: yesMathematics, 2021
The graph bandwidth problem, where one looks for a labeling of graph vertices that gives the minimum difference between the labels over all edges, is a classical NP-hard problem that has drawn a lot of attention in recent decades. In this paper, we focus

Distributionally Robust Joint Chance Constrained Problem under Moment Uncertainty

open access: yesJournal of Applied Mathematics, 2014
We discuss and develop the convex approximation for robust joint chance constraints under uncertainty of first- and second-order moments. Robust chance constraints are approximated by Worst-Case CVaR constraints which can be reformulated by a ...

Proximal-stabilized semidefinite programming [PDF]

open access: yesComputational Optimization and Applications
Abstract A regularized version of the primal-dual Interior Point Method (IPM) for the solution of Semidefinite Programming Problems (SDPs) is presented in this paper. Leveraging on the proximal point method, a novel Proximal Stabilized Interior Point Method for SDP (PS-SDP-IPM) is introduced.

A Rank-Two Feasible Direction Algorithm for the Binary Quadratic Programming

open access: yesJournal of Applied Mathematics, 2013
Based on the semidefinite programming relaxation of the binary quadratic programming, a rank-two feasible direction algorithm is presented. The proposed algorithm restricts the rank of matrix variable to be two in the semidefinite programming relaxation ...

The algebraic degree of semidefinite programming [PDF]

open access: yesMathematical Programming, 2008
Given a generic semidefinite program, specified by matrices with rational entries, each coordinate of its optimal solution is an algebraic number. We study the degree of the minimal polynomials of these algebraic numbers. Geometrically, this degree counts the critical points attained by a linear functional on a fixed rank locus in a linear space of ...
