Robust balanced optimization [PDF]

open access: yesEURO Journal on Computational Optimization, 2018
An instance of a balanced optimization problem with vector costs consists of a ground set X, a cost-vector for every element of X, and a system of feasible subsets over X.

Multipolar robust optimization [PDF]

open access: yesEURO Journal on Computational Optimization, 2018
We consider linear programs involving uncertain parameters and propose a new tractable robust counterpart which contains and generalizes several other models including the existing Affinely Adjustable Robust Counterpart and the Fully Adjustable Robust ...

Robust optimization through neuroevolution.

open access: yesPLoS ONE, 2019
We propose a method for evolving neural network controllers robust with respect to variations of the environmental conditions (i.e. that can operate effectively in new conditions immediately, without the need to adapt to variations). The method specifies

A robust robust optimization result [PDF]

open access: yesOperations Research Letters, 2012
We study the loss in objective value when an inaccurate objective is optimized instead of the true one, and show that "on average" this loss is very small, for an arbitrary compact feasible region.

Optimization and Optimizers for Adversarial Robustness

open access: yesCoRR, 2023
Empirical robustness evaluation (RE) of deep learning models against adversarial perturbations entails solving nontrivial constrained optimization problems. Existing numerical algorithms that are commonly used to solve them in practice predominantly rely on projected gradient, and mostly handle perturbations modeled by the $\ell_1$, $\ell_2$ and $\ell_\

Evaluation of Modeling Approaches for MILD Combustion Systems With Internal Recirculation

open access: yesFrontiers in Mechanical Engineering, 2020
Numerical simulations employing two different modeling approaches are performed and validated against experimental results from a moderate or intense low-oxygen dilution (MILD) system with internal recirculation. The flamelet-generated manifold (FGM) and

Frameworks and Results in Distributionally Robust Optimization

open access: yesOpen Journal of Mathematical Optimization, 2022
The concepts of risk aversion, chance-constrained optimization, and robust optimization have developed significantly over the last decade. The statistical learning community has also witnessed a rapid theoretical and applied growth by relying on these ...

PCAfold: Python software to generate, analyze and improve PCA-derived low-dimensional manifolds

open access: yesSoftwareX, 2020
Many scientific disciplines rely on dimensionality reduction techniques for computationally less expensive handling of multivariate data sets. In particular, Principal Component Analysis (PCA) is a popular method that can be used to discover the ...

Design of High Temperature Ti–Al–Cr–V Alloys for Maximum Thermodynamic Stability Using Self-Organizing Maps

open access: yesMetals, 2019
Data generated for the Ti−Al−Cr−V system of metallic alloys from our previous publication, where the composition of 102 alloys were computationally Pareto optimized with the objective of simultaneously maximizing the Young’s ...

Robust Combinatorial Optimization with Locally Budgeted Uncertainty

open access: yesOpen Journal of Mathematical Optimization, 2021
Budgeted uncertainty sets have been established as a major influence on uncertainty modeling for robust optimization problems. A drawback of such sets is that the budget constraint only restricts the global amount of cost increase that can be distributed
