An Inexact Feasible Quantum Interior Point Method for Linearly Constrained Quadratic Optimization

open access: yesEntropy, 2023
Quantum linear system algorithms (QLSAs) have the potential to speed up algorithms that rely on solving linear systems. Interior point methods (IPMs) yield a fundamental family of polynomial-time algorithms for solving optimization problems. IPMs solve a

Accuracy Verification of Surface Models of Architectural Objects from the iPad LiDAR in the Context of Photogrammetry Methods

open access: yesSensors, 2022
The creation of accurate three-dimensional models has been radically simplified in recent years by developing photogrammetric methods. However, the photogrammetric procedure requires complex data processing and does not provide an immediate 3D model, so ...

A Full-Newton step infeasible-interior-point algorithm for P*(k)-horizontal linear complementarity problems [PDF]

open access: yesYugoslav Journal of Operations Research, 2015
In this paper we generalize an infeasible interior-point method for linear optimization to horizontal linear complementarity problem (HLCP). This algorithm starts from strictly feasible iterates on the central path of a perturbed problem that is

Automatic orientation of historical terrestrial images in mountainous terrain using the visible horizon

open access: yesISPRS Open Journal of Photogrammetry and Remote Sensing, 2022
Historical terrestrial images are the only visual sources documenting alpine environments shortly after the end of the Little Ice Age. Despite their unique value, they are largely unused for quantifying environmental changes because of the difficult and ...

Counterexample to a Conjecture on an Infeasible Interior-Point Method

open access: yesSIAM Journal on Optimization, 2010
Summary: In [the second author, SIAM J. Optim. 16, No.~4, 1110--1136 (2006; Zbl 1131.90029)], Roos proved that the devised full-step infeasible algorithm has \(O(n)\) worst-case iteration complexity. This complexity bound depends linearly on a parameter \(\bar{\kappa}(\zeta)\), which is proved to be less than \(\sqrt{2n}\).

On the behavior of Lagrange multipliers in convex and nonconvex infeasible interior point methods [PDF]

open access: yesMathematical Programming, 2019
We analyze sequences generated by interior point methods (IPMs) in convex and nonconvex settings. We prove that moving the primal feasibility at the same rate as the barrier parameter $μ$ ensures the Lagrange multiplier sequence remains bounded, provided the limit point of the primal sequence has a Lagrange multiplier.

Convergence Analysis of the Inexact Infeasible Interior-Point Method for Linear Optimization [PDF]

open access: yesJournal of Optimization Theory and Applications, 2008
This article studies the use of a primal-dual interior point method for solving large scale linear programs. The article begins with a presentation of the background to this problem and an overview of the existing literature, including the use of Preconditioned Conjugate Gradients (PCG) for inexact infeasible path-following algorithms.

A penalty barrier framework for nonconvex constrained optimization [PDF]

open access: yesJournal of Nonsmooth Analysis and Optimization
We consider minimization problems with structured objective function and smooth constraints, and present a flexible framework that combines the beneficial regularization effects of (exact) penalty and interior-point methods.
