Necessary and sufficient optimality conditions in DC semi-infinite programming

R Correa, MA López, P Pérez-Aros - SIAM Journal on Optimization, 2021 - SIAM
This paper deals with particular families of DC optimization problems involving suprema of
convex functions. We show that the specific structure of this type of function allows us to …

Formulae for the conjugate and the subdifferential of the supremum function

P Pérez-Aros - Journal of Optimization Theory and Applications, 2019 - Springer
This paper aims at providing some formulae for the subdifferential and the conjungate
function of the supremum function over an arbitrary family of functions. The work is …

Qualification Conditions-Free Characterizations of the -Subdifferential of Convex Integral Functions

R Correa, A Hantoute, P Pérez-Aros - Applied Mathematics & Optimization, 2021 - Springer
We provide formulae for the ε ε-subdifferential of the integral function I_f (x):= ∫ _T f (t, x) d μ
(t) I f (x):=∫ T f (t, x) d μ (t), where the integrand f: T * X → R f: T× X→ R¯ is measurable in (t …

New extremal principles with applications to stochastic and semi-infinite programming

BS Mordukhovich, P Pérez-Aros - Mathematical Programming, 2021 - Springer
This paper develops new extremal principles of variational analysis that are motivated by
applications to constrained problems of stochastic programming and semi-infinite …

Duality-based single-level reformulations of bilevel optimization problems

S Dempe, P Mehlitz - arXiv preprint arXiv:2405.07672, 2024 - arxiv.org
Usually, bilevel optimization problems need to be transformed into single-level ones in order
to derive optimality conditions and solution algorithms. Among the available approaches, the …

Robustness in nonsmooth nonconvex optimization problems

F Mashkoorzadeh, N Movahedian, S Nobakhtian - Positivity, 2021 - Springer
In this paper, the robust approach (the worst case approach) for nonsmooth nonconvex
optimization problems with uncertainty data is studied. First various robust constraint …

[HTML][HTML] Fuzzy multiplier, sum and intersection rules in non-Lipschitzian settings: Decoupling approach revisited

M Fabian, AY Kruger, P Mehlitz - Journal of Mathematical Analysis and …, 2024 - Elsevier
We revisit the decoupling approach widely used (often intuitively) in nonlinear analysis and
optimization and initially formalized about a quarter of a century ago by Borwein & Zhu …

Moreau envelope of supremum functions with applications to infinite and stochastic programming

P Pérez-Aros, E Vilches - SIAM Journal on Optimization, 2021 - SIAM
In this paper, we investigate the Moreau envelope of the supremum of a family of convex,
proper, and lower semicontinuous functions. Under mild assumptions, we prove that the …
