On the Structure of Higher Order Voronoi Cells
Juan Enrique Martínez-Legaz, Vera Roshchina, Maxim Todorov
The classic Voronoi cells can be generalized to a higher-order version by considering the cells of points for which a given -element subset of the set of sites consists of the $…
Comparing Averaged Relaxed Cutters and Projection Methods: Theory and Examples
R. Díaz Millán, Scott B. Lindstrom, Vera Roshchina
We focus on the convergence analysis of averaged relaxations of cutters, specifically for variants that---depending upon how parameters are chosen---resemble \emph{alternating proj…
VADU 2018 Open Problem Session
Bui Thi Hoa, Scott Lindstrom, Vera Roshchina
We state the problems discussed in the open problem session at Variational Analysis Down Under (VADU2018) conference held in honour of Prof. Asen Dontchev's 70th birthday on 19--21…
A data-independent distance to infeasibility for linear conic systems
Javier Pena, Vera Roshchina
We offer a unified treatment of distinct measures of well-posedness for homogeneous conic systems. To that end, we introduce a distance to infeasibility based entirely on geometric…
Refining the partition for multifold conic optimization problems
Héctor Ramírez, Vera Roshchina
In this paper we give a unified treatment of two different definitions of complementarity partition of multifold conic programs introduced independently in [J. F. Bonnans and H. Ra…
The Demyanov-Ryabova conjecture is false
Vera Roshchina
It was conjectured by Vladimir Demyanov and Julia Ryabova in 2011 that the minimal cycle in the sequence obtained via repeated application of Demyanov converter to a finite family…
