KKT SOLUTION AND CONIC RELAXATION FOR SOLVING QUADRATICALLY CONSTRAINED QUADRATIC PROGRAMMING PROBLEMS

SIAM JOURNAL ON OPTIMIZATION, 21(4), 1475–1490.

By: C. Lu*, S. Fang*, Q. Jin*, Z. Wang & W. Xing

author keywords: quadratically constrained quadratic programming; conic programming; global optimality condition; solvable condition
TL;DR: This study leads to a global optimality condition that is more general than the known positive semidefiniteness condition in the literature and proposes a computational scheme that provides clues of designing effective algorithms for more solvable quadratically constrained quadratic programming problems.

Univariate cubic L-1 interpolating splines based on the first derivative and on 5-point windows: analysis, algorithm and shape-preserving properties

COMPUTATIONAL OPTIMIZATION AND APPLICATIONS, 51(2), 575–600.

By: Q. Jin*, L. Yu n, J. Lavery n & S. Fang n

author keywords: Cubic L-1 spline; First-derivative-based; Interpolation; Locally calculated; Shape preservation
TL;DR: It is shown that cubic L1 splines based on the first derivative and on 5-point windows preserve linearity of the original data and avoid extraneous oscillation. (via Semantic Scholar)

2010 journal article

On the global optimality of generalized trust region subproblems

OPTIMIZATION, 59(8), 1139–1151.

By: Q. Jin n, S. Fang n & W. Xing*

author keywords: global optimization; quadratic programming; generalized trust region subproblems; Lagrangian
TL;DR: The duality property between the primal problem and its Lagrangian dual problem is analysed, and the attainability of the optimal primal solution without the Slater condition is discussed. (via Semantic Scholar)
