Solving large scale linear programming [PDF]

, 1993
The interior point method (IPM) is now well established as a competitive technique for solving very large scale linear programming problems. The leading variant of the interior point method is the primal dual - predictor corrector algorithm due to ...

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 ...

A conjugate direction method for approximating the analytic center of a polytope

Journal of Inequalities and Applications, 1998
The analytic center of an -dimensional polytope with a nonempty interior is defined as the unique minimizer of the logarithmic potential function over . It is shown that one cycle of a conjugate direction method, applied to the potential function at

Worst-Case Linear Discriminant Analysis as Scalable Semidefinite Feasibility Problems

, 2014
In this paper, we propose an efficient semidefinite programming (SDP) approach to worst-case linear discriminant analysis (WLDA). Compared with the traditional LDA, WLDA considers the dimensionality reduction problem from the worst-case viewpoint, which ...

Curvature continuity in arbitrary bicubic Bezier patches [PDF]

Two methods are outlined for imposing interpatch curvature continuity in existing Bezier bicubic patch surfaces. Each method assumes that coordinates of the corners of the patches can not be altered but the interior Bezier control point can.
