A Coordinate-Free Condition Number for Convex Programming
We introduce and analyze a natural geometric version of Renegar’s condition number R, which we call Grassmann condition number, for the homogeneous convex feasibility problem associated with a regular cone C ⊆ R. Let Grn,m denote the Grassmann manifold of m-dimensional linear subspaces of R with the Riemannian distance metric dg. The set of ill-posed instances Σm ⊂ Grn,m consists of the linear ...
متن کاملMinimizing Condition Number via Convex Programming
In this paper we consider minimizing the spectral condition number of a positive semidefinite matrix over a nonempty closed convex set Ω. We show that it can be solved as a convex programming problem, and moreover, the optimal value of the latter problem is achievable. As a consequence, when Ω is positive semidefinite representable, it can be cast into a semidefinite programming problem. We the...
متن کاملRobust smoothed analysis of a condition number for linear programming
We perform a smoothed analysis of the GCC-condition number C (A) of the linear programming feasibility problem ∃x ∈ R Ax < 0. Suppose that Ā is any matrix with rows ai of euclidean norm 1 and, independently for all i, let ai be a random perturbation of ai following the uniform distribution in the spherical disk in S of angular radius arcsinσ and centered at ai. We prove that E(ln C (A)) = O(mn/...
متن کاملUniform Smoothed Analysis of a Condition Number for Linear Programming
Bürgisser, Cucker, and Lotz [arxiv:math.NA/0610270] proved a general theorem providing smoothed analysis estimates for conic condition numbers of problems of numerical analysis. Applications to linear and polynomial equation solving were given. We show that a suitable modification of the general theorem in that paper, adapted to a spherical convex setting, allows to analyze condition numbers of...
متن کاملCondition number and eccentricity of a closed convex cone
We discuss some extremality issues concerning the circumradius, the inradius, and the condition number of a closed convex cone in Rn. The condition number refers to the ratio between the circumradius and the inradius. We also study the eccentricity of a closed convex cone, which is a coefficient that measures to which extent the circumcenter differs from the incenter.
