Data‐Based Refinement of Parametric Uncertainty Descriptions

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 6, Page 3210-3228, April 2026.
ABSTRACT We consider dynamical systems with a linear fractional representation involving parametric uncertainties which are either constant or varying with time. Given a finite‐horizon input‐state or input‐output trajectory of such a system, we propose a numerical scheme which iteratively improves the available knowledge about the involved constant ...

Semidefinite Programming and Ramsey Numbers

open access: yes, 2020
Finding exact Ramsey numbers is a problem typically restricted to relatively small graphs. The flag algebra method was developed to find asymptotic results for very large graphs, so it seems that the method is not suitable for finding small Ramsey ...

Product Rules in Semidefinite Programming [PDF]

open access: yes, 2007
In recent years we witness the proliferation of semidefinite programming bounds in combinatorial optimization [1,5,8], quantum computing [9,2,3,6,4] and even in complexity theory [7]. Examples to such bounds include the semidefinite relaxation for the maximal cut problem [5], and the quantum value of multi-prover interactive games [3,4].

Generalized Gauss Inequalities via Semidefinite Programming

open access: yes
A sharp upper bound on the probability of a random vector falling outside a polytope, based solely on the first and second moments of its distribution, can be computed efficiently using semidefinite programming.

Bounds for codes by semidefinite programming [PDF]

open access: yesProceedings of the Steklov Institute of Mathematics, 2008
Delsarte's method and its extensions allow to consider the upper bound problem for codes in 2-point-homogeneous spaces as a linear programming problem with perhaps infinitely many variables, which are the distance distribution. We show that using as variables power sums of distances this problem can be considered as a finite semidefinite programming ...

Affine scaling algorithm fails for semidefinite programming [PDF]

open access: yes, 1997
In this paper, we introduce an affine scaling algorithm for semidefine programming (SDP), and give an example of a semidefinite program such that the affine scaling algorithm converges to a non-optimal point.

A semidefinite program for distillable entanglement [PDF]

open access: yesIEEE Transactions on Information Theory, 2001
We show that the maximum fidelity obtained by a p.p.t. distillation protocol is given by the solution to a certain semidefinite program. This gives a number of new lower and upper bounds on p.p.t. distillable entanglement (and thus new upper bounds on 2-locally distillable entanglement).

k-Point semidefinite programming bounds for equiangular lines

open access: yes, 2021
We propose a hierarchy of k-point bounds extending the Delsarte–Goethals–Seidel linear programming 2-point bound and the Bachoc–Vallentin semidefinite programming 3-point bound for spherical codes.

On the central paths and Cauchy trajectories in semidefinite programming [PDF]

open access: yes, 2004
summary:In this work, we study the properties of central paths, defined with respect to a large class of penalty and barrier functions, for convex semidefinite programs.
