We show by examples that optimum and robust controllers, designed by using the H/sub 2/, H/sub /spl infin//, l/sup 1/ and /spl mu/ formulations, can produce extremely fragile controllers, in the sense that vanishingly small perturbations of the coefficients of the designed controller destabilize the closed loop control system.

We address the problem of estimating risk-minimizing portfolios from a sample of historical returns, when the underlying distribution that generates returns exhibits departures from the standard Gaussian assumption. Specifically, we examine how the underlying estimation problem is influenced by marginal heavy tails, as modeled by the univariate Student-

Qualitatively, a filter is said to be ''robust'' if its performance degradation is acceptable for distributions close to the one for which it is optimal, that is, the one for which it has been designed. This paper adapts the signal-processing theory of optimal robust filters to classifiers.

A distributional interpretation of robust optimization
2010 48th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2010Motivated by data-driven decision making and sampling problems, we investigate probabilistic interpretations of robust optimization (RO). We establish a connection between RO and distributionally robust stochastic programming (DRSP), showing that the solution to any RO problem is also a solution to a DRSP problem.

Robust control with optimization of robustness index
2012 IEEE International Conference on Systems, Man, and Cybernetics (SMC), 2012The paper considers a problem of robust control system synthesis based on the modified algorithm of Coefficient Diagram Method (CDM) with robustness index optimization. The proposed solution is expected to enable improvement of system robustness against parametric uncertainty.

Robust Optimization for Clustering
2016In this paper, we investigate the robust optimization for the minimum sum-of squares clustering (MSSC) problem. Each data point is assumed to belong to a box-type uncertainty set. Following the robust optimization paradigm, we obtain a robust formulation that can be interpreted as a combination of MSSC and k-median clustering criteria.

Stability and Continuity in Robust Optimization
SIAM Journal on Optimization, 2017Summary: We consider the stability of robust optimization (RO) problems with respect to perturbations in their uncertainty sets. In particular, we focus on robust linear optimization problems, including those with an infinite number of constraints, and consider uncertainty in both the cost function and constraints.

Optimality and Robustness of the English Auction [PDF]
Games and Economic Behavior, 2001 In \textit{P. R. Milgrom} and \textit{R. J. Weber}'s [``A theory of auctions and competitive bidding'' Econometrica 50, 1089-1122 (1982; Zbl 0487.90017)] ``general symmetric model'', under a few additional regularity conditions, the English auction maximizes the seller's expected profit within the class of all posterior-implementable trading procedures
