Implementation of interior-point methods for LP based on Krylov subspace iterative solvers with inner-iteration preconditioning [PDF]
Computational optimization and applications, 2016 We apply novel inner-iteration preconditioned Krylov subspace methods to the interior-point algorithm for linear programming (LP). Inner-iteration preconditioners recently proposed by Morikuni and Hayami enable us to overcome the severe ill-conditioning ...

On the Turing Model Complexity of Interior Point Methods for Semidefinite Programming [PDF]
SIAM Journal on Optimization, 2015 It is known that one can solve semidefinite programs to within fixed accuracy in polynomial time using the ellipsoid method (under some assumptions). In this paper it is shown that the same holds true when one uses the short-step, primal interior point ...

Optimal Correction of Infeasible Systems in the Second Order Conic Linear Setting [PDF]
Computer Science Journal of Moldova, 2011 In this paper we consider correcting infeasibility in a second order conic linear inequality by minimal changes in the problem data. Under certain conditions, it is proved that the minimal correction can be done by solving a lower dimensional convex ...

New complexity analysis of full Nesterov-Todd step infeasible interior point method for second-order cone optimization [PDF]
Yugoslav Journal of Operations Research, 2018 We present a full Nesterov-Todd (NT) step infeasible interior-point algorithm for second-order cone optimization based on a different way to calculate feasibility direction. In each iteration of the algorithm we use the largest possible barrier parameter

Interior Point Methods for Massive Support Vector Machines [PDF]
, 2000 We investigate the use of interior point methods for solving quadratic programming problems with a small number of linear constraints where the quadratic term consists of a low-rank update to a positive semi-de nite matrix. Several formulations of the

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

An infeasible interior point methods for convex quadratic problems
Journal of Numerical Analysis and Approximation Theory, 2018 In this paper, we deal with the study and implementation of an infeasible interior point method for convex quadratic problems (CQP). The algorithm uses a Newton step and suitable proximity measure for approximately tracing the central path and ...
