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

Entropy, 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

Primal-dual interior point QP-free algorithm for nonlinear constrained optimization [PDF]

Journal of Inequalities and Applications, 2017
In this paper, a class of nonlinear constrained optimization problems with both inequality and equality constraints is discussed. Based on a simple and effective penalty parameter and the idea of primal-dual interior point methods, a QP-free algorithm ...

Quantum Interior Point Methods for Semidefinite Optimization [PDF]

Quantum, 2023
We present two quantum interior point methods for semidefinite optimization problems, building on recent advances in quantum linear system algorithms. The first scheme, more similar to a classical solution algorithm, computes an inexact search direction ...

Boundary Matching and Interior Connectivity-Based Cluster Validity Anlysis

Applied Sciences, 2020
The evaluation of clustering results plays an important role in clustering analysis. However, the existing validity indices are limited to a specific clustering algorithm, clustering parameter, and assumption in practice.

Interior Point Methods

Journal of Computational and Applied Mathematics, 2000
The simplex method starts from a basic feasible solution and moves along the boundary of the feasible region until an optimum is reached. At each step, the algorithm brings only one new variable into the basic set, regardless of the total number of variables.

Large-step predictor-corrector interior point method for sufficient linear complementarity problems based on the algebraic equivalent transformation

EURO Journal on Computational Optimization, 2023
We introduce a new predictor-corrector interior-point algorithm for solving P⁎(κ)-linear complementarity problems which works in a wide neighbourhood of the central path.

Predator survival analysis of a Prey-Predator system with prey species pool

Scientific African, 2021
In this paper we study prey-predator relationship in the presence of prey species pool. We describe the set of parameters when the predator will survive and find the threshold when you lose predator survival.
